Wonderware DASMBTCP with ABB CM30 Modbus TCP
The communication work very well.
I can switch from manual mode to auto and vice-versa.
The item adress i use is "1".
But im having some trouble to find the right adresses for PV, SP, CV variables.
I know that Holding Register begin at 40001.
But in the ABB manual the adress for SP is 6639 so i try 46639 as item name but no succes ?
I did same for:
6779 Loop 1 Proportional Band 1
6781 Loop 1 Integral Time 1
6783 Loop 1 Derivative Time 1
Nothing work with holding register.
Help appreciate :)
ok i find the solution.
1 - have to set the ABB CM30 Communication: Reverse IEEE Data = YES
2 - have to use Absolute Notation Item Names (help of MBTCP DAS server)
to read Loop1 PB - Register 6779
i have to write item name (In Intouch) like that: 6778 HRF
