0211 Duplicate master address 00 00 to 7D: Failing
Master Address
Check the master devices on the
network and ensure that they have
unique device addresses.
0219 Hardware error 00 00 • 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.
