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
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.
The station number set as the screen data
does not exist in the Ethernet setting of GT
Designer.
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
limit]
1. Check for any disconnected cable or
improperly fitted 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 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.)
Add the station number set as the screen data
to the Ethernet setting of GT Designer.
(Use the station number of the PLC side
Ethernet module set in the parameter setting of
GX Developer.)
