?Corrected from:
PLC Designer V3.9
Response of the new version:
The exception no longer occurs.
What happens?
When double-clicking on an I/O module on the backplane bus of the Controller in the PLC project, the following exception occurs:
"IoProvider not found in host."
When does this behaviour occur?
The exception occurs, if "Exclude from build" has been selected as property for an I/O module on the backplane bus.
Which products are affected?
PLC Designer V3.6 and higher
Short-term measures:
Deactivate the "Exclude from build" option and select "Disable device".
Evaluation/recommendations:
If you want to transfer a PLC project to a Controller although less I/Os are connected on the backplane bus of the Controller than are available in the PLC project, the missing I/O modules (devices) have to be deactivated. If the I/O modules are not deactivated but excluded from compiling ("Exclude from build"), a double-click on these modules will lead to an exception.
