Auto clear PROG. mode and correct the error.
The same relay is used multiple times in OT instruction, etc.
Switch to the PROG. mode and correct the error. Or, set the

mode and enter the two instructions which must be used in a
pair in the correct positions.
Applicable instructions and cases are as follows.
Stop
• MC and MCE are not paired.
Auto clear
• LBLs corresponding to LOOP and JP are not located in the
same area (normal program area / same sub-routine area /
same interrupt program area).
• There are no sub-routines corresponding to CALL and
FCALL.
• There is no STPE corresponding to SSTP.
An instruction that can only executed in a specified area is
written in another location. Switch to the PROG. mode and
correct the error.
Applicable instructions and cases are as follows.
• LBL, LOOP, JP, MC and MCE are in the stepladder area.
• MC is nested in more than 16 layers.
• CNDE is outside the normal program area.
Stop
• EDPB is outside the blank area.
Auto clear
• ED is inside the sub-routine area or the interrupt area.
• SBL is outside the blank area or the sub-routine area.
• An interrupt program is outside the blank area or the interrupt
program area.
• RET is outside the sub-routine area.
• IRET is outside the interrupt program area.
• STPE is outside the stepladder area.
In the program, high-level instructions, which execute in every
scan and at the leading edge of the trigger, are programmed to

high-level instructions executed in every scan and only at the
leading edge are triggered separately.
The program is too large to compile in the program memory.
Stop
Switch to the PROG. mode and reduce the total number of
Auto clear
steps for the program.
