hello guys

i am working on a project in which i am using Quantum PLC and WinCC 7.2 SCADA system.

i have done the addressing part using MODBUS technique.

now the problem is how would i know that my scada is connected to plc on MODBS TCP/IP.

i have assigned the ip to PLC and modbus driver in winCC.

but i can't make it work.

can anyone help me on this....

Closed, cause question posted twice.

The second thread is published with the subject Trying to communicate WinCC 7.2 with Modicon Quantum PLC using MODBUS.

Best regards
