In the CANopen mode the I/O system does not automatically reset the function Save and Load on index I1010h and I1011h

Which products are affected?
EPM-T110 1A 11 (CAN Gateway module firmware 1.1)
EPM-T83x 1A 11 (Compact modules firmware 1.1)

What happens?
The CANopen mode enables you to access and write the indices I1010h (Save) and I1011h (Load) in the ASCII format. If the indices are accessed and written by a CANopen parameter setting tool of another manufacturer, the values of these indices will not be reset automatically by the I/O system after the function has been executed. This reaction is the contrast to the known GDC reaction 'store parameter set' via index I2003h.

When does the problem occur?
The problem only occurs in CANopen mode and parameter access with a CANopen parameter setting tool. When the parameter setting software GDC is used the indices I1010h and I1011h are not available (they are not contained in the PDBs), as the parameter setting tool GDC does not support the processing of ASCII values.

Possible diagnostics?
In the CANopen parameter setting tool the indices I1010h and I1011h keep the value 'Save' or 'Load' and are not reset.

Short-term measures / recommendations?
The user is not able to modify the described behaviour.

Evaluation:
The function 'Save' and 'Load' is correctly executed in the device. The successful execution of the function is, however, not indicated immediately to the user.
