Dear All,

I would like to connect S7-1517 CPU with EPICS.

I used s7-EPICS device support. But it gives and error

s7nodaveConfigureIsoTcpPort("lcpcPLC", "10.20.80.211", 0, 2, 0)

Could not connect to PLC for port lcpcPLC: daveConnectPLC() failed with status code -1.

2020/03/09 16:52:22.430 lcpcPLC -1 autoConnect could not connect

May be PLC is refusing the connection.

Please help me to connect S7-1517 CPU.

Thank you.

Vishnu
