– The number of modules actually mounted is
different from that is set in Network parame-
ter for CC-Link IE controller network.
– The head I/O number of the actually mounted
module is different from the one set in the
network parameter of the CC-Link IE control-
ler network.
– Data cannot be handled in the parameter
existing.
– The network type of CC-Link IE controller net-
work is overwritten during power-on. (When
changing the network type, switch RESET to
RUN.)

 Diagnostic Timing
At power ON/At reset/STOP → RUN
– Check the network parameters and actual
mounting status, and if they differ, make them
match.
When network parameters are modified, write
them to the CPU module.
– Check the setting of extension base unit stage
number.
– Check the connection status of extension
base unit and extension cables. When the
GOT is busconnected to the main base unit or
extension base unit, also check its connection
status.
If the error occurs even after the above checks,
the possible cause is a hardware fault.
Contact your local Mitsubishi representative.
