Adapter,PC Adapter,PC Adapter CN

Adapter

An adapter or adaptor is a device that converts attributes of one device or system to those of an otherwise incompatible device or system.

Some adapters may only affect physical attributes:

  • An electrical adapter may enable connection of a socket used in one region to a plug used in another by offering connections for the disparate contact arrangements, while not changing the voltage. For more, see: AC power plugs and sockets.
  • A garden hose adapter can convert between threads and quick-release, "snap"-type connections.
  • One kind of serial port adapter enables connections between 25-contact and nine-contact connectors, but does not affect electrical power- and signalling-related attributes.

Other adapters may affect electrical attributes:

  • A transformer adapts household electric current from high voltage (100 to 240 volts AC) to low voltage suitable for consumer electronics. These adapters will warm through converting alternating current to direct current, but are safe to the environment and can withstand months of continuous prolonged activity. 

                  PC Adapter CN is one of them.

How to Install a Wireless Communication Card on a Laptop

Instructions

Installing a Communication Card

  • 1

    Open the panel labeled PCMCIA on the left side of the computer

  • 2

    Insert the card into the slot. The edge of the card with the roll of connection holes must go in first. Check the card's markings to determine which side should face up. If the card doesn't have any markings, slide the card in label up.

  • 3

    Do not force the card into the slot. If it doesn't go in easily, then you have not inserted it correctly. The card is fully inserted if the Eject button to the right of the slot pops out. Within a few seconds after the card has been inserted, the computer will make a confirmation sound. If there is no sound, then you have turned off the computer's speaker or the basic PCMCIA drivers have not been properly loaded.

Ejecting the Card

  • 4

    Press the PCMCIA card Eject button. The card should pop out slightly.

  • 5

    Gently slide it out the rest of the way. Within a few seconds the computer will make a sound confirming that the system recognizes that the card has been ejected.

  • Tips & Warnings

  •  

    Some types of PCMCIA cards may require you to install special drivers. These drivers are supplied by the card manufacturer.

  •  

    When inserting a PCMCIA card into one of the PCMCIA slots, the computer will go to sleep. This is necessary to maintain a link between the system and the card just inserted.

How Does a Wireless Communication Card Work?Communication card, CP5611 card, CP5611/CP5611-A2

How Does a Wireless Communication Card Work?

How wireless cards connect with a computer

  • A wireless communication card works with a USB or PC card slot to connect a computer to the Internet. The card is inserted into the USB port on a computer or a slot. The slots on old computers are for PCMCIA cards, which are roughly 2 inches in width. The newer computers have Express cards, which are only a little wider than an inch. Both the PCMCIA and Express card are more convenient than the USB wireless cards because they don't protrude very far out of the slot on your computer. USB wireless cards can be bumped into things, especially when connected to a laptop. The upside to the USB style of wireless card is the fact that newer computers are coming out with more USB ports. Still, the PCMCIA and Express cards are most durable for anyone traveling with wireless Internet.

 

How infrastructure mode works with wireless cards

  • Infrastructure mode is the most common type of wireless communication card type, often referred to as Wi-Fi. The infrastructure mode requires that a hotspot be present. Typically, today's home Internet connection may consist of a connection to the internet via DSL or cable, a computer for each occupant of the home and a wireless router. The wireless signal is broadcast up to about 100 feet. Each family member can access the Internet from the hotspot or wireless router via a wireless card connected to each computer. Individual IP addresses are assigned to each computer on the home network.

How ad-hoc mode works with wireless cards

  • Ad-hoc wireless mode has become one alternative to DSL or cable ISP providers. With ad-hoc wireless communication type cards, the user accesses the Internet through his wireless provider without a hotspot. This means no messy cables or phone lines in the house. The wireless card working in ad-hoc mode uses the signal from nodes sharing the same frequency by the wireless carrier supplying the wireless ISP service. Ad-hoc doesn't need a LAN line or a wireless router. In fact, ad-hoc mode doesn't need DSL or cable either.

    Wireless cards using the ad-hoc mode require a data plan. This plan can be made through a wireless carrier, such as a mobile phone company. Before signing up with a wireless carrier, one should request a data map from each carrier, because different parts of the United States have better wireless data coverage than others. Using a cellular network is great for anyone who travels a lot. It is a much more affordable alternative to using satellite.

    The wireless card can be connected to any computer but will only work with one computer at a time. Alternatively, the ad-hoc wireless card can be made into a hotspot to share connectivity with nearby computers. For privacy and security reasons, it is best not to create a hotspot with your ad-hoc wireless connection.

mitsubushi,usb adapter, usb-sc09

Mitsubushi

Mitsubishi_logo.svgThe Mitsubishi Group (三菱グループ, Mitsubishi Gurūpu) (also known as the Mitsubishi Group of Companies or Mitsubishi Companies) is a group of autonomous Japanese multinational companies covering a range of businesses which share the Mitsubishi brand, trademark, and legacy.

The Mitsubishi group of companies form a loose entity, the Mitsubishi Keiretsu, which is often referenced in Japanese and US media and official reports; in general these companies all descend from the zaibatsu of the same name. The top 25 companies are also members of the Mitsubishi Kin'yōkai, or "Friday Club", and meet monthly. In addition the Mitsubishi.com Committee exists to facilitate communication and access of the Mitsubishi brand through a portal web site.

USB adapter

A USB adapter is a type of protocol converter which is used for converting USB data signals to and from other communications standards. Commonly, USB adaptors are used to convert USB data to standard serial port data and vice versa.

Most commonly the USB data signals are converted to either RS232, RS485, RS422 or TTL serial data. The older serial RS423 protocol is rarely used any more, so USB to RS423 adapters are hard to find.

Uses

USB to serial RS232 adapters are often used with consumer, commercial and industrial applications and USB to serial RS485/RS422 adapters are usually mainly used only with industrial applications.

Adapters for converting USB to other standard or proprietary protocols also exist; however, these are usually not referred to as a serial adapter.

The primary application scenario is to enable USB based computers to access and communicate with serial devices featuring D-Sub (usually DB9 or DB25) connectors or screw terminals, where security of the data transmission is not generally an issue.

USB serial adapters can be isolated or non-isolated. The isolated version has opto-couplers and/or surge suppressors to prevent static electricity or other high-voltage surges to enter the data lines thereby preventing data loss and damage to the adapter and connected serial device. The non-isolated version has no protection against static electricity or voltage surges, which is why this version is usually recommended for only non-critical applications and at short communication ranges.

Mitsubishi PLC Programming Replacement Cable USB SC09
USB Cable for Mitsubishi MELSEC FX and A series PLC. 8 pin DIN connector and DB-25 connector. Designed for computers without a serial port. This cable is an OEM replacement and not made by Mitsubishi.

Introduction
USB-SC09 is the programming cable in which USB interface provides both the serial connection and RS422 signal conversion. Under the control of computer-driven driver, the programming cable makes it possible for the computer's USB interface to simulate the traditional serial (known as COM interface), thus various existing programming software such as communications software, monitoring software and other applications can be normally used. The working power supply of this cable is directly from the USB port, but not the PLC programming interface. The two-color LED on the converter box indicates data�s transceiving status.

USB-SC09 principle and figure structure:

Functions
● Support USB-SC09 operating system: Windows2000/XP(WinNT4/95/98/Me/DOS not support )
● Support USB-SC09 programming software version: FXGP / WIN V1.0,GPP V4.0, GX Developer V7.0 and above.
● Fully compatible with USB V1.1 norms and USB CDC V1.1
● USB-bus powered, with current consumption of 50 mA
● Baud rate: 300 bps ~ 1Mbps automatically adapt to the standard baudrate
● Support UART data format: data bits: 7-8; stop bit: 1, 2; check-bit: odd /even / no parity
● Each PC only supports one USB cable programming
● Working temperature: -20 ~ +75 ℃

●Color: black

Usage:

USB device drivers should be installed before using USB-SC09 programming cable. After completing Driver installation, the corresponding COM port for the USB-SC09 programming cable will be displayed in the "Device Manager" of Window. The step next is just to choose this COM port in the programming software and other application software and keep other communication parameters as in the Default settings. And the following steps are exactly the same as in the traditional programming cables with RS232 interfaces.


Note: DB25M plugs and MD8M plugs of the RS422 interface can not be used at the same time.

PLC Automation, PLC Logic, Omron PLC

PLC Automation, PLC Logic, Omron PLC

Recent years, PLC Automation is more and more necessary in Industrial, or in our daily life. So we need to talk about something named PLC Logic. As follows, I will take Omron PLC for example.

PLC Automation

plc-automated-systemplc automation

 

PLC automation is used for control of many types of machines. The subject of automation is vast. Automation is the combination mechanization and intelligence. Intelligence of using sensors and data with a logic or computing device to eliminate the need of human control.

Much of automation does not rely on PLCs. Take for instance business automation. Here the mechanization is much less "machine" and really a process. Custom software and other applications are implemented after studying processes to link information together and streamline operations.

Machines assist Humans with many tasks that require strength and repetition. Automation makes machines smart,well as least as smart as the programmer makes them. To add automation to a machine you need a brain of some sort…a PLC for instance. With a PLC, a machine can handle things that a human cannot. Whether the process is too fast, slow, small, big, cold, hot or just too dangerous for humans then an automated machine is the solution.

You also need a bunch of sensors/transducers for sensory data for the PLC. The eyes, ears, and touch if you will of the PLC. The sensors are your PLC inputs which it uses within its program to process and select the outputs. The PLC outputs can be valves, motors, solenoids, servos, lights, pneumatic or hydraulic cylinders. Basically, any device that you would use to give a machine motion or alert an operator you would connect to a PLC output.

Other systems that enable automation are embedded processors or micro-controllers. These are used in your homes washer/dyer, microwave oven, dishwasher, and may even your toaster. These hard goods are massed produced and therefore the smaller, less expensive micro- controllers are used. Speaking of homes what about using a PLC for home automation?

PLC Logic

Before the advent of solid-state logic circuits, logical control systems were designed and built exclusively around electromechanical relays. Relays are far from obsolete in modern design, but have been replaced in many of their former roles as logic-level control devices, relegated most often to those applications demanding high current and/or high voltage switching.

Systems and processes requiring "on/off" control abound in modern commerce and industry, but such control systems are rarely built from either electromechanical relays or discrete logic gates. Instead, digital computers fill the need, which may be programmed to do a variety of logical functions.

In the late 1960's an American company named Bedford Associates released a computing device they called the MODICON. As an acronym, it meant Modular Digital Controller, and later became the name of a company division devoted to the design, manufacture, and sale of these special-purpose control computers. Other engineering firms developed their own versions of this device, and it eventually came to be known in non-proprietary terms as a PLC, or Programmable Logic Controller. The purpose of a PLC was to directly replace electromechanical relays as logic elements, substituting instead a solid-state digital computer with a stored program, able to emulate the interconnection of many relays to perform certain logical tasks.

A PLC has many "input" terminals, through which it interprets "high" and "low" logical states from sensors and switches. It also has many output terminals, through which it outputs "high" and "low" signals to power lights, solenoids, contactors, small motors, and other devices lending themselves to on/off control. In an effort to make PLCs easy to program, their programming language was designed to resemble ladder logic diagrams. Thus, an industrial electrician or electrical engineer accustomed to reading ladder logic schematics would feel comfortable programming a PLC to perform the same control functions.

PLCs are industrial computers, and as such their input and output signals are typically 120 volts AC, just like the electromechanical control relays they were designed to replace. Although some PLCs have the ability to input and output low-level DC voltage signals of the magnitude used in logic gate circuits, this is the exception and not the rule.

Signal connection and programming standards vary somewhat between different models of PLC, but they are similar enough to allow a "generic" introduction to PLC programming here. The following illustration shows a simple PLC, as it might appear from a front view. Two screw terminals provide connection to 120 volts AC for powering the PLC's internal circuitry, labeled L1 and L2. Six screw terminals on the left-hand side provide connection to input devices, each terminal representing a different input "channel" with its own "X" label. The lower-left screw terminal is a "Common" connection, which is generally connected to L2 (neutral) of the 120 VAC power source.

PLC Automation, PLC Logic, Omron PLC

Inside the PLC housing, connected between each input terminal and the Common terminal, is an opto-isolator device (Light-Emitting Diode) that provides an electrically isolated "high" logic signal to the computer's circuitry (a photo-transistor interprets the LED's light) when there is 120 VAC power applied between the respective input terminal and the Common terminal. An indicating LED on the front panel of the PLC gives visual indication of an "energized" input:

Output signals are generated by the PLC's computer circuitry activating a switching device (transistor, TRIAC, or even an electromechanical relay), connecting the "Source" terminal to any of the "Y-" labeled output terminals. The "Source" terminal, correspondingly, is usually connected to the L1 side of the 120 VAC power source. As with each input, an indicating LED on the front panel of the PLC gives visual indication of an "energized" output:

In this way, the PLC is able to interface with real-world devices such as switches and solenoids.

The actual logic of the control system is established inside the PLC by means of a computer program. This program dictates which output gets energized under which input conditions. Although the program itself appears to be a ladder logic diagram, with switch and relay symbols, there are no actual switch contacts or relay coils operating inside the PLC to create the logical relationships between input and output. These are imaginary contacts and coils, if you will. The program is entered and viewed via a personal computer connected to the PLC's programming port.

Consider the following circuit and PLC program:

When the pushbutton switch is unactuated (unpressed), no power is sent to the X1 input of the PLC. Following the program, which shows a normally-open X1 contact in series with a Y1 coil, no "power" will be sent to the Y1 coil. Thus, the PLC's Y1 output remains de-energized, and the indicator lamp connected to it remains dark.

If the pushbutton switch is pressed, however, power will be sent to the PLC's X1 input. Any and all X1 contacts appearing in the program will assume the actuated (non-normal) state, as though they were relay contacts actuated by the energizing of a relay coil named "X1". In this case, energizing the X1 input will cause the normally-open X1 contact will "close," sending "power" to the Y1 coil. When the Y1 coil of the program "energizes," the real Y1 output will become energized, lighting up the lamp connected to it:

It must be understood that the X1 contact, Y1 coil, connecting wires, and "power" appearing in the personal computer's display are all virtual. They do not exist as real electrical components. They exist as commands in a computer program — a piece of software only — that just happens to resemble a real relay schematic diagram.

Equally important to understand is that the personal computer used to display and edit the PLC's program is not necessary for the PLC's continued operation. Once a program has been loaded to the PLC from the personal computer, the personal computer may be unplugged from the PLC, and the PLC will continue to follow the programmed commands. I include the personal computer display in these illustrations for your sake only, in aiding to understand the relationship between real-life conditions (switch closure and lamp status) and the program's status ("power" through virtual contacts and virtual coils).

The true power and versatility of a PLC is revealed when we want to alter the behavior of a control system. Since the PLC is a programmable device, we can alter its behavior by changing the commands we give it, without having to reconfigure the electrical components connected to it. For example, suppose we wanted to make this switch-and-lamp circuit function in an inverted fashion: push the button to make the lamp turn off, and release it to make it turn on. The "hardware" solution would require that a normally-closed pushbutton switch be substituted for the normally-open switch currently in place. The "software" solution is much easier: just alter the program so that contact X1 is normally-closed rather than normally-open.

In the following illustration, we have the altered system shown in the state where the pushbutton is unactuated (not being pressed):

In this next illustration, the switch is shown actuated (pressed):

One of the advantages of implementing logical control in software rather than in hardware is that input signals can be re-used as many times in the program as is necessary. For example, take the following circuit and program, designed to energize the lamp if at least two of the three pushbutton switches are simultaneously actuated:

To build an equivalent circuit using electromechanical relays, three relays with two normally-open contacts each would have to be used, to provide two contacts per input switch. Using a PLC, however, we can program as many contacts as we wish for each "X" input without adding additional hardware, since each input and each output is nothing more than a single bit in the PLC's digital memory (either 0 or 1), and can be recalled as many times as necessary.

Furthermore, since each output in the PLC is nothing more than a bit in its memory as well, we can assign contacts in a PLC program "actuated" by an output (Y) status. Take for instance this next system, a motor start-stop control circuit:

The pushbutton switch connected to input X1 serves as the "Start" switch, while the switch connected to input X2 serves as the "Stop." Another contact in the program, named Y1, uses the output coil status as a seal-in contact, directly, so that the motor contactor will continue to be energized after the "Start" pushbutton switch is released. You can see the normally-closed contact X2 appear in a colored block, showing that it is in a closed ("electrically conducting") state.

If we were to press the "Start" button, input X1 would energize, thus "closing" the X1 contact in the program, sending "power" to the Y1 "coil," energizing the Y1 output and applying 120 volt AC power to the real motor contactor coil. The parallel Y1 contact will also "close," thus latching the "circuit" in an energized state:

Now, if we release the "Start" pushbutton, the normally-open X1 "contact" will return to its "open" state, but the motor will continue to run because the Y1 seal-in "contact" continues to provide "continuity" to "power" coil Y1, thus keeping the Y1 output energized:

To stop the motor, we must momentarily press the "Stop" pushbutton, which will energize the X2 input and "open" the normally-closed "contact," breaking continuity to the Y1 "coil:"

When the "Stop" pushbutton is released, input X2 will de-energize, returning "contact" X2 to its normal, "closed" state. The motor, however, will not start again until the "Start" pushbutton is actuated, because the "seal-in" of Y1 has been lost:

An important point to make here is that fail-safe design is just as important in PLC-controlled systems as it is in electromechanical relay-controlled systems. One should always consider the effects of failed (open) wiring on the device or devices being controlled. In this motor control circuit example, we have a problem: if the input wiring for X2 (the "Stop" switch) were to fail open, there would be no way to stop the motor!

The solution to this problem is a reversal of logic between the X2 "contact" inside the PLC program and the actual "Stop" pushbutton switch:

When the normally-closed "Stop" pushbutton switch is unactuated (not pressed), the PLC's X2 input will be energized, thus "closing" the X2 "contact" inside the program. This allows the motor to be started when input X1 is energized, and allows it to continue to run when the "Start" pushbutton is no longer pressed. When the "Stop" pushbutton is actuated, input X2 will de-energize, thus "opening" the X2 "contact" inside the PLC program and shutting off the motor. So, we see there is no operational difference between this new design and the previous design.

However, if the input wiring on input X2 were to fail open, X2 input would de-energize in the same manner as when the "Stop" pushbutton is pressed. The result, then, for a wiring failure on the X2 input is that the motor will immediately shut off. This is a safer design than the one previously shown, where a "Stop" switch wiring failure would have resulted in an inability to turn off the motor.

In addition to input (X) and output (Y) program elements, PLCs provide "internal" coils and contacts with no intrinsic connection to the outside world. These are used much the same as "control relays" (CR1, CR2, etc.) are used in standard relay circuits: to provide logic signal inversion when necessary.

To demonstrate how one of these "internal" relays might be used, consider the following example circuit and program, designed to emulate the function of a three-input NAND gate. Since PLC program elements are typically designed by single letters, I will call the internal control relay "C1" rather than "CR1" as would be customary in a relay control circuit:

In this circuit, the lamp will remain lit so long as any of the pushbuttons remain unactuated (unpressed). To make the lamp turn off, we will have to actuate (press) all three switches, like this:

This section on programmable logic controllers illustrates just a small sample of their capabilities. As computers, PLCs can perform timing functions (for the equivalent of time-delay relays), drum sequencing, and other advanced functions with far greater accuracy and reliability than what is possible using electromechanical logic devices. Most PLCs have the capacity for far more than six inputs and six outputs. The following photograph shows several input and output modules of a single Allen-Bradley PLC.

PLC Automation, PLC Logic, Omron PLC

With each module having sixteen "points" of either input or output, this PLC has the ability to monitor and control dozens of devices. Fit into a control cabinet, a PLC takes up little room, especially considering the equivalent space that would be needed by electromechanical relays to perform the same functions:

One advantage of PLCs that simply cannot be duplicated by electromechanical relays is remote monitoring and control via digital computer networks. Because a PLC is nothing more than a special-purpose digital computer, it has the ability to communicate with other computers rather easily. The following photograph shows a personal computer displaying a graphic image of a real liquid-level process (a pumping, or "lift," station for a municipal wastewater treatment system) controlled by a PLC. The actual pumping station is located miles away from the personal computer display:

Introduction

USB-CIF02 programming cable simulates USB port as traditional serial port (usually COM3).The working power supply of this cable is directly from the USB port, but not the PLC programming interface. The two-color LED on the converter box indicates data’s transceiving status.

USB-CIF02 is applicable to Omron PLC,which can directly connect with CPM1,CPM1A,CPM2A,CPM2AH,C200HS,C200HX/HG/HE and SRM1 series PLC; for CS / CJ, CQM1H and CPM2C series PLC , please choose USB-CN226 programming cable, but also can connect with CS / CJ, CQM1H and CPM2C series PLC via CS1W-CN114 cable adapter.

 

Note: USB-CIF02 can not be used to the old model C200H, C_ _ H, C500-AP003, 3G2A5-AP003 series PLC.

Usage:

USB device drivers should be installed before using USB-CIF02 programming cable, which are available on the CD-ROM sold together with the cable. And for the specific installation steps, please refer to the instruction files on the CD-ROM drivers, and details are not necessarily listed here.

After completing Driver installation, the corresponding COM port for the USB-CIF02 programming cable will be displayed in the “Device Manager” of Window. The step next is just to choose this COM port in the programming software and other application software and keep other communication parameters as in the Default settings. And the following steps are exactly the same as in the traditional programming cables with RS232 interfaces.

Long-distance communications:

 USB-CIF02 programming cable does not support long-distance communication. For long-distance communication, RS485/422 communication module can be chosen (model: FS-CIF11), which makes dozens of PLC communicate, with the largest communication range of up to 2 Km.  
Please Note: USB interface cannot be extended.
