For the first time I have a load of analog signals being transferred into my Control Logix system via Modbus. I have sent analog to a DCS via Modbus by a COP instruction with the analog address/tagname copied to the Modbus Transfer file for 2 - 16 bit words. The DCS reassembles the data to read the analog signal.
Is there a tried and true method for receiving analog signals from a DCS? My blind attempt has been the following:
COP:
Source DCS_2_CAL[100}
Destination TIT_12345
Length 2
I'm sure this has been done before but I'm not sure and will not be traveling to debug this system, I'd like to have it right before I ship it.
