Possible causes and remedies
The device is switched on, but is not reachable due to erroneous parameteri-
zation of the communication parameters.
Ensure that the communication parameters in the
Modbus AFB are coordinated between the master and slave and/or client and
server.
OR

The error tolerance during data import or data export of a register is too low.
On a test basis, increase the Error filter parameter under:

OR
[Master and slave]
At least one register is incorrectly or not at all parameterized on one of the two
sides.
Use the operation panel of the enCore device in the display belonging to the
Modbus AFB and check which registers are not regularly refreshed. On both
sides, check for errors in the respective parameterization concerning these
register numbers.
OR
[Master and slave]
The cabling is defective or there is a cable breakage.
Check the cabling and replace the damaged cable.
