?Corrected from:
PLC Designer V3.12
Response of the new version:
When switching between the subtabs of the EtherCAT master tab no exception occurs.
What happens?
The following exception occurs when changing between PLC Designer tabs:
Collection was modified; enumeration operation may not execute.
When does this behaviour occur?
The exception may occur if many EtherCAT nodes are available and the EtherCAT Master tab is left, opened or it is changed between the subtabs of the EtherCAT Master tab.
Which products are affected?
PLC Designer V3.0 and higher
Short-term measures:
Go to the Exception dialog, click <Continue> and save the project. After this, you can continue working as usual.
Evaluation/recommendations:
In PLC Designer projects with many EtherCAT nodes, an Exception may occur. If you click <Continue> in the Exception dialog, you can continue working as usual. If you click <Quit>, the PLC Designer will be closed and unsaved changes in the project will get lost.
