Hello expert.

In the plant, there is a Scada using WinCC V7.4 SP1. WinCC is running in Redundant Single-user stations mode ( 2x WinCC V7.4 SP RT license and 1 WinCC Redundancy license)

The 2 stations both connect to the PLCs in the process.

Now my customer wants to create another network, for IEC 104 communication with other Scada. So i plant on buying Simatic Wincc Telecontrol V7.4.

But the problem is the description in the sales/delivery confuses me a lot.

• WinCC single-user system

• Single or redundant WinCC Server

• Single or redundant WinCC Server that creates an additional connection to other PLC
  
  
  So in my case, it is WinCC single-user system, but the WinCC is communicating with PLCs using Profinet. so will this telecontrol add-on work on my plant?
  
  Thank you
