7 Troubleshooting and Maintenance
Correction
Check the master devices on the
network and ensure that they have
unique device addresses.
• Check the network wiring, and
make sure it is correct.
• Check for short-circuits.
• Check the bus timing set through
CX-ConfiguratorFDT.
• Check the HSA setting in CX-
ConfiguratorFDT and make sure it
is set to the master device with
the highest address on the net-
work.
• Check if any other faulty devices
are on the same network.
• Verify that the Highest Station
Address setting includes any
other master address on the bus.
Recreate the data specified by the
2nd byte of the detailed error code.
Restart the CPU Unit. If the problem
persists, replace the PROFIBUS
Master Unit.
