C1BDH The target station number of the link dedicated instruction
is incorrect.
• Execute the link dedicated instruction again after
correcting the target station number.
• When specifying another network station, check if the
settings in "Routing Setting" of "CPU Parameter" are
made correctly.
C1BEH The command code of the dedicated instruction is
incorrect.
• Execute again after correcting the command code at
the request source.
• If the request source is on another network, check if
the routing parameters are set correctly, and take
action.
C1BFH The channel used in the dedicated instruction is
incorrect.
• Execute again after correcting the used channel within
the allowable range at the request source.
• If the request source is on another network, check if
the routing parameters are set correctly, and take
action.
C1C0H The transient data is incorrect. • Correct the transient data at the request source, and
retry the operation.
• If the error occurs again even after taking the above,
please consult your local Mitsubishi representative.
C1C1H The transient data is incorrect. • Correct the transient data at the request source, and
retry the operation.
• If the error occurs again even after taking the above,
please consult your local Mitsubishi representative.
C1C2H When the dedicated instruction was executed, data was
received twice.
• Check the network status and take corrective action
using the Ethernet diagnostics of the engineering tool.
• Check if the switching hub and the cables at the
request source are connected properly.
• If the request source is on another network, check if
the routing parameters are set correctly, and take
action.
C1C4H The arrival check of the link dedicated instruction was
completed with an error.
• Execute link dedicated instruction again after changing
the execution type in the control data to "No arrival
acknowledgment".
• For the REQ instruction, execute again after correcting
request type.
C1C5H A dedicated instruction which the target station does not
support was executed.
• Change the target station at the station that executed
the SEND instruction.
• If the error occurs again even after taking the above,
please consult your local Mitsubishi representative.
C1C6H The execution or error completion type of the dedicated
instruction is incorrect.
• Execute again after correcting the execution/error
completion type in the control data.
• If the problem cannot be resolved with the above
actions, the possible cause is a hardware failure of the
module. Please consult your local Mitsubishi
representative.
C1C7H The request type of the REQ instruction is incorrect. • Execute again after correcting the request type of the
REQ instruction.
• If the problem cannot be resolved with the above
actions, the possible cause is a hardware failure of the
module. Please consult your local Mitsubishi
representative.
C1C8H The channel specified in the dedicated instruction is in
use.
Change the channels used by own station or the target
station's channel in the control data.
C1C9H The device specification for the ZNRD/ZNWR instruction
is not correct.
• Execute again after correcting the device specification
for the ZNRD/ZNWR instruction.
• If the problem cannot be resolved with the above
actions, the possible cause is a hardware failure of the
module. Please consult your local Mitsubishi
