•
Compare your selected cable lengths with the technical
data in the appendix and the recommendations of the
CiA specification.
•
Check the installation of the terminating resistors at both
ends of the fieldbus.
•
Test the fieldbus communication using the object directory
(see section A.2).
Normal status LED MNS-LED is off and I/O-LED illuminates green (in operational
mode) or is off (in the event of defective fieldbus communica-
tion).
3.1.5 Check the CANopen configuration
Problem description: Process data is faulty.
Remedy: Proceed as follows:
1. Check whether the mapping element conforms to the set-
tings of the master controller (see section A.2).
2. Check whether the status of the bus node, e. g. opera-
tional mode, complies with the settings of the master con-
troller (see section 2.2.5).
Problem description: Outputs do not switch to the desired state in the event of
fieldbus communication malfunctions.
Remedy: Proceed as follows:
1. Check whether Node guarding or Heartbeat is activated
on the master controller.
This ensures that the bus node can detect malfunctions in
fieldbus communication and that the outputs are set to a
defined state after fieldbus communication is restored.
2. Check whether Fail State is activated on the bus node
(DIL switch position).
Fail State off: the outputs are set to “0” after fieldbus
communication is restored.
