Correction
2nd byte
Replace the PLC CPU Unit.
Check the operating environment. Saved
Replace the CPU Unit.
Replace the CPU Unit.
01: Recreate the data specified by
the 2nd byte of the detailed error
code.
02: Clear memory using proce-
dure in the PLC operation manual.
Set the destination address in the
routing tables.
Set the local node, remote node
and relay nodes in the routing
tables.
Create the routing tables cor-
rectly.
Reconstruct the network or cor-
rect the routing tables so that
commands are set to within a 3-
level network range.
Check the command format and
set the correct command data.
Check the routing tables.
• Check the parameter settings.
• Re-download the configuration
if necessary.
Check the master devices on the
network, and make sure they are
all working correctly.
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-Profibus.
• Check the HSA setting in CX-
Profibus, 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 net-
work.
• Verify that the Highest Station
Address setting includes any
other master address on the
bus.
