Hello mz.nap; If you look at the attached document, which is extracted from an (old) WinCC v.6 communication manual I still have on my harddisk, you will see the available channels to exchange between WinCC and a PLC (in those days, a Siemens PLC). The opened page relates to MPI communications, aRS-485 based network; there exists a RS-232 to MPI converter named a PC-Adapter (nowadays probably a USB-Adapter). The PC-Adapter is often used to program and monitor the S7 PLC, when Ethernet connections are not available. However, if you look at the drawing on the opened page of the pdf you will see a notice that for connection to WinCC over MPIyou would need a "MPI ISA card", at the time this would be refering to a CP 5611. There was no option for linking WinCC to a S7 PLC using the PC-Adapter. I believe there is still no option of the kind for newer versions of WinCC. The WinCC V. 6 communications manual is still available on Siemens Support site, if you want to check out your options: WinCC V6 Communication Manual Hope this helps, Daniel Chartier |
