Connecting between Hysys, ControlLogix and Intouch Wonderware


Thread Starter


I'm successfully connecting between intouch wonderware 10 and Hysys 3.2 via excel file, PID algorithm is based on hysys software.
Now I'm try to connect Hysys, intouch and Real PLC (controllogix). I want PID algorithm based on controllogix not Hysys anymore.

So please help me what a component palette in hysys that can be used as a transmitter (process variable) and what component palette that can be used to feed manipulate variable at control valve. thank you

Use the Wonderware IO Server DASABCIP to connect InTouch to ControlLogix. You will need an IO Server license on your InTouch node (InTouch with IO).
you can use OPC, the order is as follows:

data of process variable from hsysy plant is transfered to OPC. then from OPC you can give directly to PLC(hardware). in PLC is used in PID algorithm. the manipulated variable then must be transfered to hysys plant or valve in hysys via OPC again from OPC to hysys. that finish.
