Corrective action
Read common information of the error using
the programming tool to identify the numeric
value (program error location). Check the
error step corresponding to the value, and
correct it as necessary.
Write the program to the CPU module again
using the programming tool.
Write the program to the CPU module again
using the programming tool.
Write the program to the CPU module again
using the programming tool.
Write the program to the CPU module again
using the programming tool.
Correct the program so that the number of
steps in the SFC program may not exceed
the total number of step relays.
Increase the total number of step relays in the
Device tab of "PLC Parameter".
Write the program to the CPU module again
using the programming tool.
Correct the total number of step relays so that
it does not exceed the total number of
(maximum step No.+1) of each block.
Increase the total number of step relays in the
Device tab of "PLC Parameter".
