Set up Mudbus RTU to Servo Drive to read and write holding registers. I can run "Test Modbus" without any issues, all requested input and outputs read and write correctly. I have setup my Modbus configuration using the same parameters. Created and Enabled a simple Brain that compares the CFG(0) Modbus input to turn off/on an output but I only get 0.0000 in my Modbus Reading. Have also tried similer ouput (CFG)'s and Brains, it only wants to send 0.0000. Any ideas what I am missing???
Thank You,
Brandon
