Lost the communication with the PLC
I lost the communication with the OPC server for few seconds while downloading the programs
version is 800xA 5.1FP4 , Type of the PLC is PM866
Can anybody suport.
How long is the Stop Time during Download of the Controller?
If download takes too long, the OPC Server will timeout.
Long delays during download can have multiple reasons, what I know is that user defined communication like Modbus TCP can cause this.
An easy way to improve is to split code in multiple applications that can then be downloaded independently.
