Hello, very sry you have still problems. If you can, use also that termination. Pls make tests as I've sugested to you before: 1. omit real device and connect PC with suitable adapter and some MB SW simulated Slave to your PLC CB module. You can check on short distance if your code working correctly. 2. connect PC with MB RTU master SW and make test to real HW if you can receive data due needed requests. Look, you must make tests, also look to www.simplymodbus.ca for help about Modbus and useful SW, also on first topic post here is Smiffy's good Modbus description which can be also helpful. |
With best regards... |
