How to add a RS232 to RS485 converter to a ACE PLC?
It is sometimes useful to be able to connect the ACE PLC to an RS485 network.
- connect hundreds ACE PLC on the same RS485 network
- connect a HMI to a ACE PLC far away from the each other where the RS232 is not enough (10 meters about)
- connect an ACE PLC to an external sensor or device: Small display, variable-frequency drive, smart sensor,..
The ACE 1430 and 1450 already have a built-in RS232/485 port, but for the others a small RS232 to RS485 signal converter must be added. It’s not the ideal solution, but it can be useful as our industrial ACE are very powerful and cheap.

The RS232/485 converter is powered via the RS485 network. It is not necessary to power it.
