[STEP EXE. ERROR]
• Startup was attempted at the step that does not
exist in the SFC program.
Or, the step that does not exist in the SFC
program was specified for end.
• Forced transition was executed based on the
transition condition that does not exit in the SFC
program.
4631

*1 CPU operations when an error occurred can be determined with a parameter. (LED indication varies according to the
CPU module status.)
*8 This applies if the function version is B or later.
*10 This applies when the first five digits of the serial number is "04101" or later.
*11 This applies when the first five digits of the serial number is "07012" or later.
*12 This applies when the first five digits of the serial number is "07032" or later.
*15 This applies when the first 5 digits of the serial No. is "09102" or later
*18 This applies to the Universal model QCPU except for the Q00UJCPU.
*19 This applies to the Universal model QCPU except for the Q00UJCPU, Q00UCPU, and Q01UCPU.
*20 This applies to the Universal model QCPU except for the Q00UJCPU, Q00UCPU, Q01UCPU, and Q02UCPU.
*21 This applies to the Built-in Ethernet port QCPU.
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.
