Hi Guys,
I'm trying to connect a non-brand LED display to the 1756-L63 ControlLogix. The display can communicate via RS232 (one direction), RS422, RS485, and TCP/IP (both directions). According to the manual available protocols are: Serial RGB and Modbus RTU (Modbus RTU only on RS485). I am able to display messages on the display using Hercules Setup Utility app. I tried RS232 and TCP/IP and both works. But I don't know how to make it work with the PLC. I assume the MSG instruction could be helpful, but i don't know how to configure it. I was trying to broadcast the message (CIP Generic, Parameter Write) over the RS232, but i'm getting the error 16#00f2 "Broadcasting not supported for current system protocol or data size invalid". I was trying all available system protocols, but always the same error. I also have the HMS Anybus Communicator AB7007-C which, i'm guessing, could be useful, but i have never play with it. Any ideas on how to make the display work with PLC?
