The original project used Simatic net v8.0 and I can see on S7 connections that the two S7-1200 have two-way communications. The S7 connection shows twice per device. On the virtual machine, with WinCC v7.5, I have installed the Simatic Net v16, and on the PG with TIA portal I changed the device version of the OPC server from v8.0 to v16, now I can only have one of the PLC's with two-way communication, the other PLC it's only one way and the options on special connection properties are grayed out (inactive). What's he limitation that I will have having one way communication? With OPC v8 I have imported the XDB configuration file to WinCC v7.5 and did not have any error. I have to change the version of OPC v8 to v16 since on the machine that will run WinCC has that version? ------------------------------------------------------------------------------------------ |
