prebone Posted May 26, 2015 Report Share Posted May 26, 2015 Is it possible to use the UAC-02RS2 IO module for Modbus communication? I would like to communicate on a RS232 port with a Radio. Link to comment Share on other sites More sharing options...
s.pratt Posted May 26, 2015 Report Share Posted May 26, 2015 Hello, As of now, the two ports capable of Modbus communication are COM1 (RS485 port on CPU) and the Ethernet port on the panel. Is it possible to use RS485 communication with the radio? Link to comment Share on other sites More sharing options...
prebone Posted May 26, 2015 Author Report Share Posted May 26, 2015 Thank's for quick response, mr Pratt! I found in the documentation on the radio (SATEL EASy 869) that they are programmable to RS422, I'll check further with my dealer on this. Else I usually use modbus TCP on the ethernet port, but this time I need to go on the air. Sorry I didn't check if modbus worked on the Uni-COM modules before ordering, I took it for granted and was fooled again. ;-) Regards Preben Link to comment Share on other sites More sharing options...
