Fixed as of:
PLC Designer version 3.14 and later
Behavior of the new version:
The "Generate All SDOs" checkbox is no longer selectable for the EPM-S110.
Description of the behavior:
The parameters of the I/O1000 CAN bus coupler are reset to their default settings. Depending on the set baud rate, the CAN bus may become inoperable.
Under what conditions does this behavior occur?
After a (cold) reset, the controller resets all parameters of the I/O1000 CAN bus coupler to their default values if the "Generate All SDOs" checkbox has been selected for this bus coupler on the "CANopen Remote Device" tab.
Affected products:
PLC Designer version 3.3 and later
EPM-S110 (I/O1000 CAN bus coupler)
Short-term measures:
Uncheck the "Generate all SDOs" checkbox for the I/O1000 CAN bus coupler.
Assessment/Recommendations:
If the "Generate All SDOs" checkbox is selected, all slave parameters are transferred to the slave, regardless of whether the default value has been changed or not. With the I/O1000 CAN bus coupler, this causes the parameters to be reset to their default settings.
