PLC programming cables for several brands
- Omron PLC cables
- Mitsubishi PLC cables
- Siemens PLC cables
- Idec / Izumi PLC cables
- Unitronics PLC cables
- Z-World micro-controller cables
Most PLC’s can be programmed from a PC via a serial cable. Unfortunately, many of these cables have a non standard layout. The cables shown here can be bought from the regular sales channels, but it is often much cheaper to solder them yourself.
Idec / Izumi PLC’s
Idec / Izumi PLC series FA2, FA2J and FA3J all require a special communication adapter for programming. This communication link adapter (CLA) is a small box that converts the RS232 electrical signals into a compatible level for the PLC. The cable to connect the PC to a CLA uses a DB25 connector at the PLC side. The layout for a cable with a DB9 connector at the PC side is shown here.
Z-World is an American company specialized in developing micro-controller boards based on the Z180 and Rabbit series micro-controllers. Where PLCs are often used in single piece environments, micro-controllers are mainly present in the OEM world where multiple controllers are needed.
The main difference in programming a PLC is that most micro-controllers, including those from Z-World, are programmed in C. The Z-World programming package runs on a normal PC and the connection with the controller is made using a serial cable. This cable needs a DB9 connector at one and, and a RJ14 plug at the other. The pin out of a programming cable is shown here.
