multiple OMS+ connection

[papillon11]

hello everyone
i hope you all have a good time
what is the maximum OMS+ connection for wincc 7.5 ? this is maybe a repetitive question but i couldnt find straight answer. all i find is about SIMATIC S7 Protocol Suite
and thats why i need to know because i wanted to create OMS+ connections for totall 20 number of 1511c plc. so is it possible ? can be done with regular network card or specific CP card needed ?
any help will be appreciated
best regards

You can use the regular network card for up to 64 connections. The standard Siemens WinCC includes a Softnet S7 Lean / Basis license, which allows up to 8 connections. If you want to use more than 8 connections, you have to buy the Softnet IE S7 license.
