Is it possible to configure two Named connections between the same S7 400 communication processor and the WinCC app; the first Named connection will be ISO communication and the second Named connection will be TCP? i want by this configuration to work by both connections at the same time , if one of the connections has a problem the other will work.

Hi Sowma, this will not work. Because when you compile your OS you have to select one of these connections and all tags will be inside this connection mapping. The second connection has no data and so you can not control your process. If you want to have something similar as you requested you can: a) use a redundant PLC as of S7-400H, there you can have fault tolerant connection to each of both CPU (redconnect software out of SIMATIC NET needed) b) use a S7-400H single PLC with to Ethernet CP cards and again redconnect software to set up a fault tolerant connection c) use an single S7-400H PN/DP PLC with one additional Ethernet CP and redconnect See the following manual for all these possibilities: https://support.industry.siemens.com/cs/de/en/view/82478488 Regards |

is it possible to use the redundant connection in WinCC to switch between the two named connections |
