Probable cause
Check the Unit indicated in A417.
Refer to the Unit's operation manual
to find and correct the cause of the
error. Restart the Unit by toggling its
Restart Bit or turn the power OFF
and ON again.
Replace the Unit if it won't restart.
Check the Unit indicated in A418 to
A423. Refer to the Unit's operation
manual to find and correct the cause
of the error. Restart the Unit by tog-
gling its Restart Bit or turn the power
OFF and ON again.
Replace the Unit if it won't restart.
Mount the I/O Unit in the Backplane.
If the error is not recurs, replace the
I/O Unit.
Check battery and replace if neces-
sary. Change the PLC Setup setting
if battery-free operation is being
used.
Change the registered I/O tables.
Review the program and either dis-
able detecting interrupt task errors or
prevent redundant refreshing from
occurring.
