Error
Code
Error Message Definition Action
356
File system error occurred in
the PLC
When the file register name is designated and then
the recipe function is operated, an error occurs in
the designated file register.
1. Check the file register name, and then operate
the recipe function again.
2. Apply Format PLC memory to the designated
PLC drive with the GX Developer, and then
operate the recipe function again.
357
The specified drive of PLC is
abnormal
When the file register name is designated and then
the recipe function is operated, there is a fault in
the PLC drive.
1. Check the designated PLC drive, and then oper-
ate the recipe function again.
2. Apply Format PLC memory to the designated
PLC drive with the GX Developer, and then
operate the recipe function again.
358 File of PLC access failure
When the file register name is designated and then
the recipe function is operated, the PLC file regis-
ter could not be accessed.
1. Check the designated PLC drive/ file register
name, and then operate the recipe function
again (If drive 0 was designated, change to a
different drive, and then operate the recipe func-
tion again).
2. Check whether the memory card is write-pro-
tected, and then operate the recipe function
again.
359
Processing is from another
peripheral device
When the file register name is designated and then
the recipe function is operated, other peripheral
devices begin processing for the file register.
Wait until the peripheral devices finish operating,
and then operate the recipe function again.
360 Division error due to divisor of 0 Divisor 0 occurred in the data operation formula
Reconsider the data operation formula to avoid the
divisor of 0
370
Contradiction in magnitude rela-
tionship of upper and lower limit
values
Upper and lower limit values have been set as
[upper limit lower limit]
Check the upper and lower limit value setting and
correct them to be [upper limit lower limit]
402 Communication time-out Time-out error occurred during communication
1. Check for any disconnected cable or improperly
fitted communication board/communication
module
2. This may occur if the programmable logic con-
troller load is increased while accessing another
station. In this case, move the other station's
data to the local station's programmable logic
controller, and monitor with the local station.
3. If the sequence scan is long, insert a COM com-
mand.
403 SIO request status error
At the time of receive during RS-422/RS-232C
communication, any of overrun error, parity bit
error and framing error occurred.
Check the cable connection status, the communi-
cation board/communication module mounting sta-
tus, the PLC status, and the communication link
transmission speed.
406
Specified station doesn’t access
for out of range
(1) The station number specified for CC-Link con-
nection (via G4) is other than that of the master/
local station.
(2) Access was made to the CPU other than the
QCPU.
Check the station number of the monitor screen
data.
407
Other network accessed by
MNET10 module
Access was made to the other network at the time
of MELSECNET connection (network system)
Check the network number in the screen data to
avoid access to the other network
421
The specification of E71 cannot
be written
The Ethernet module on the PLC side has been
set for write disable.
Set the PLC side Ethernet module for write enable.
422
It is not communicate between
the CPU and E71
The CPU is faulty or communication cannot be
made between the CPU and PLC side Ethernet
module.
Check the CPU for any fault using GX Developer
or like. (Check the buffer memory.)
