Datasocket and NI Modbus TCP library

[_EMG_]

Hello,

we're using in a project (LV7.1) the NI ModbusTCP library and the DataSocket server. The PC connects as Modbus client to a PLC to get process data, the DataSocket server is used for a "remote" connection with an additional PC. Everything is normally working well, but I found out that in the moment when an addition PC connects as a DataSocket client to the server, the loop for PLC connection needs about 1..1,5sec more execution time.

This causes a connection error in the PLC although the connection doesn't hang up. After that, the PLC loop runs in normal condition again (execution time 100ms).

This behaviour appears while the DataSocket clients disconnects, too.

What might be this?!?  Thanks for help!
