10.2.9 Step relay (S)
Step relays are devices for SFC programs.
Refer to the following manual for how to use the step relays.
QCPU (Q Mode)/QnACPU Programming Manual (SFC)
POINT
Because the step relay is a device exclusively for the SFC program, it cannot be
used as an internal relay in the sequence program.
If used in this manner a SFC error will occur, and system operation will be stopped
(system down).
