I need to control ABB Drives via Modbus TCP (AC800M). Does ABB have any tested library for this?
I have done some logics for this but they are not fully tested and I am not confident at all with them.
In another hand, for me is quite surprising that it seems that no libraries for controlling drives (with their standard profidrive sequence) via Profibus or Modbus are available.
For controlling drives by ProfiBus there are several libraries. Besides all specific libraries for pulp&paper, minerals, metals and so on, you have ProcessObjDriveLib which I beleive is contained within the standard package.
I bet that some unit within ABB also has a solution for ModBus communication. Check with your local representative.
