SP7: SP7 open (connect.vi) Error 66

[Raabun]

Hello,

I tried to optimize my sample rate.

I the first step of my state mashine i try to open the connection to the PLC S7-1200.

I feed the SP7 open block with the plc-Type (s7-1200 = 2), timeout =5000ms, Rack =2 and IP adress = 192.168.1.39

My plc type CPU1215F DC/DC/DC produces always the Error 66.

Why? And does somebody knows a solution?

regards

Raabun

Please check the settings of the Ethernet port of your PLC in TIA portal. Explanation for error 66 is "Connection closed by the peer" hence it seems that the PLC is refusing the connection made by LabVIEW.
