SIMATIC WinCC Open Architecture Forum

Hello,

Does WinCC OA support IEC 60870-5-101 (Slave) or IEC 60870-5-103 (Master) Protocols?

Best regards,

Nedžad Agić

In WinCC OA you can use the IEC driver for IEC 60870-5-104 (TCP/IP data transmission) and IEC 60870-5-101 (for serial connection).
For details please have a look at the WinCC OA Documentation: Drivers --> IEC
