Definition
When the file register name is designated and
then the recipe function is operated, an error
occurs in the designated file register.
When the file register name is designated and
then the recipe function is operated, there is a
fault in the PLC drive.
When the file register name is designated and
then the recipe function is operated, the PLC file
register could not be accessed.
When the file register name is designated and
then the recipe function is operated, other
peripheral devices begin processing for the file
register.
Divisor 0 occurred in the data operation formula
Upper and lower limit values have been set as
[upper limit
lower limit]
Time-out error occurred during communication
At the time of receive during RS-422/RS-232C
communication, any of overrun error, parity bit
error and framing error occurred.
(1) The station number specified for CC-Link
connection (via G4) is other than that of the
master/local station.
(2) Access was made to the CPU other than the
QCPU.
Access was made to the other network at the
time of MELSECNET connection (network
system)
The Ethernet module on the PLC side has been
set for write disable.
The CPU is faulty or communication cannot be
made between the CPU and PLC side Ethernet
module.
MELSEC-GOT
Action
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.
1. Check the designated PLC drive, 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.
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
function again).
2. Check whether the memory card is write-
protected, and then operate the recipe
function again.
Wait until the peripheral devices finish operating,
and then operate the recipe function again.
Reconsider the data operation formula to avoid
the divisor of 0
Check the upper and lower limit value setting
and correct them to be [upper limit
1. Check for any disconnected cable or
improperly fitted communication
board/communication module
2. This may occur if the programmable logic
controller 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
command.
Check the cable connection status, the
communication board/communication module
mounting status, the PLC status, and the
communication link transmission speed.
Check the station number of the monitor screen
data.
Check the network number in the screen data to
avoid access to the other network.
Set the PLC side Ethernet module for write
enable.
Check the CPU for any fault using GX
Developer or like. (Check the buffer memory.)
