Which products are affected?
ESP-DDS2-P (Drive PLC Developer Studio Professional V2.3)
What happens?
If a POU, which has been programmed in the CFC (Continuous Function Chart) programming language, is opened the DDS logs off and indicates the communication error #0.
If the CFC editor is already opened during the project download, the PLC target system cannot be used for monitoring purposes – DDS logs off immediately and indicates the communication error #0.
When does the problem occur?
If a POU which has been written in the CFC programming language is opened while the DDS is online, the communication error #0 may occur dependent on the number of variables to be monitored. As a result, DDS logs off.
Possible diagnostics?
None.
Short-term measures/recommendations?
None.
Evaluation:
If a POU is opened while the DDS is online, the DDS software logs off and indicates the communication error mentioned before. Thus, trouble shooting in the DDS project becomes much more difficult.
