Description
The hardware of the network module is faulty.
Please consult your local Mitsubishi representative.
Confirm the set values (mode, etc.) in the control data of a dedicated
instruction.
The hardware of the network module is faulty.
Please consult your local Mitsubishi representative.
Check if the CPU module model of the target station specified in the WRITE,
READ, REQ, RRUN, RSTOP, RTMRD, and RTMWR instructions is out of
applicable range.
Re-execute the REMFR or REMTO instruction after a little while.
Confirm the operation status of the target station, the network status, and the
relay station status (in the case of sending to other network).
Check if the buffer memory address specified in the REMFR and REMTO
instructions exceeds 8000 .
H
Check if the network number specified in the REMFR and REMTO instructions
represents a PLC to PLC network.
Check if the host station is data-linked when the REMFR or REMTO instruction
is executed.
Confirm the setting of the mode switch.
If the error reoccurs after resetting, the hardware of the network module is
faulty.
Please consult your local Mitsubishi representative.
Create new network parameters and perform Write to PLC.
If the error reoccurs, the hardware of the CPU or network module is faulty.
Please consult your local Mitsubishi representative.
Check if the station number is within a range of 1 to 64.
If the error reoccurs even if the station number is set between 1 and 64, the
hardware of the network module is faulty.
Please consult your local Mitsubishi representative.
Create new network parameters and perform Write to PLC.
If the error reoccurs, the hardware of the CPU or network module is faulty.
Please consult your local Mitsubishi representative.
The hardware of the network module is faulty.
Please consult your local Mitsubishi representative.
The hardware of the CPU or network module is faulty.
Please consult your local Mitsubishi representative.
The hardware of the network module is faulty.
Please consult your local Mitsubishi representative.
Replace the network module of the control or normal station with the one
compatible with the MELSECNET/H Extended mode.
Change the network type of the normal station to that of the control station.
Create new network parameters and perform write to PLC.
If the error reoccurs, the hardware of the CPU or network module is faulty.
Please consult your local Mitsubishi representative.
Create new network parameters and perform Write to PLC.
If the error reoccurs, the hardware of the CPU or network module is faulty.
