Mitsubishi PLC Cable Layout

Mitsubishi PLC

Melsec Mitsubishi PLC Cable from Mitsubishi can be connected to PC’s running Medoc programming software using various cables. Each different I/O module uses a different pin assignment.

Mitsubishi PLCMitsubishi PLC

Main Unit

All-in-one power supply, CPU, and I/O main unit. Built-in features include high-speed counters and positioning outputs.

I/O Extension

Both [I/O Extension Units] with a built-in power supply and [I/O Extension Blocks] without a power supply are available in various I/O sizes and configurations.

 Analog Control:

Options for analog inputs and outputs, temperature sensor inputs, and temperature control are available.

 High-Speed Counting

Options are available to increase the performance of the built-in high-speed counters or provide additional high-speed counting capacity. etc

Mitsubishi PLC Cable

Not all Mitsubishi PLCs can be connected directly to a programming PC. The signal levels of the A series CPU units are not RS232 compatible and must be converted with a SC-02N or SC-05 converter. The serial cable layout to connect this converter to a PC is shown in this diagram.

If more than one serial port is necessary on an A series melsec PLC, the AJ71C24 or AJ71C21 serial communication modules can be plugged into the system. These modules provide RS232 compatible serial ports, so no signal conversion is necessary to connect these modules with a PC. Both modules are equipped with a DB25 connector. The cable layout for these two modules is shown below.

aj71c24The A1SJ71C24-R2 can also be used to connect computers and devices to a melsec series A PLC. This plug-in module contains two serial ports, each with a DB9 connector. The wiring layout is in fact identical to the RS232 null modem cable with loopback handshaking.
