What is the PRO-RS485 Cable Used For?
The PRO-RS485 cable plugs into the programming port of any CPU and provides RS485 capability for it.
You can therefore use this to provide RS485 communications to CPU’s that do not support expansion modules, such as PR-6 and PR-12 Series.
Furthermore, if you use it with a CPU which has a built-in RS485 port, such as PR-14 and PR-24, then it provides a second independant isolated RS485 connection for the CPU.
