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
