Corrected from:
PLC Designer V03.20.00
Response of the new version:
A double-sided write operation to a string variable is possible without errors.
What happens?
The OPC-UA server of the controller crashes or is no longer accessible.
When does the behaviour occur?
It is written from both sides (PLC and OPC-UA client) to the same string variable. The write process is sporadically performed simultaneously.
Which products are affected?
PLC Designer V3
Short-term measures:
The string variable should only be described from one side. If necessary, a second variable can be used for the opposite direction.
