Created HMI tags. When work reached to a network configuration, at communication control between 11 1214с controlers and the workstation with WinCC V11 in Network View I can not connect more than 8 controlers with PC Station. They certainly appear in the connectons tab, but with a red background, I so understood that it is impossible to add more than 8 connections. It is WinCC limits number of connections or this restriction on HW ? What SW i need to solve the problem? Engineers in SIEMENS Kazakhstan office did`nt gave any answer. Help, give any advice or references. Thanks. Attachment Device & network view.jpg (809 Downloads)

I do not know the limit, but if it stopped at 8, like you, I would certainly guess the limit is 8. I know the S7-1200 controllers can only handle 8 _simultaneous connections. Assume the basic HMIs are similarly configured. However, the WinCC V11 RT Adv might have a work-around. Maybe time fora support request if you need to know the optimal solution to the problem you are trying to solve?
