I am communicating from a micro 820 to ignition edge through modbus tcp. My coil is working but my holding register values are not connecting. I dont know what I am doing wrong. Does anyone see anything wrong with these values?
Micro 820:
Ignition Modbus Mapping Table:
Looks like Modicon addressing, which uses a numeric prefix to indicate the area to read from, and your Modbus Address in both cases should just be 1.
Hey Kevin, I do not follow. The Modbus address coming out of the PLC is 40001. If its only a 16bit address then that should also appear in ignition as 40001. Is that not right?
Nevermind, I got it to work. I just changed the 40001 address to HR1
