UNISAB II RS2LAN Communication with WinCC or Simatic PLCs

[wsk@]

Dear all,
My customer has 3 JCI/YORK compressors with UNISAB II controlers. All controlers are conected via Danbus to RS2LAN converter. Converter is connected to PC with SabVisual SCADA.

Customer wants chnage PC with SCADA system. He prefer Siemens SCADA WinCC Professional V13 and SIMATIC S7 PLC controllers(S7-1200 or S7-1500).

Do anyone know what kind of software I need to communicate RS2LAN with WinCC or S7 PLCs ?
I supose that I need some OPC driver. Do anyone have this driver?
Maybe someone have a documentation to R2LAN converter?

Thanks in advance for answers.

Easy way is to retrofit the Unisab II to Unisab III.

Dear torque,

This is a quite expensive solution. To communicate with Unisab III you need a *.gsd file to PROFBUS DP. Maybe you have got it?
