Operation
Turns on when there is an error in the expansion block side
such that the power to the expansion unit is not on or the
Stop expansion cable is not connected correctly when the power
turns on. The wait time until the power turns on can be set in
the I/O map configuration dialog box.
Operation
Stop
A program with a syntax error has been written. Switch to the
PROG. mode and correct the error.
Auto clear
The same relay is used multiple times in OT instructions, etc.
Switch to the PROG. mode and correct the error. Or, set the
duplicated output to "enable" in the CPU configuration.
Stop
Auto clear Applicable devices and instructions are as follows.
● Operation device (X, Y, R, L), timer/counter instruction,
SSTP instruction
For instructions which must be used in a pair, one instruction
is either missing or in an incorrect position. Switch to the
PROG. 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 subroutine
area / same interrupt program area)
● No subroutine corresponding to CALL and FCALL
● 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 step ladder area
● MC is nested in more than 16 levels
● CNDE is outside the normal program area
Stop
● EDPB is outside the free area
Auto clear
● ED is inside the subroutine area or the interrupt area
● SBL is outside the free area or the subroutine area
● An interrupt program is outside the free area or the
interrupt program area
● RET is outside the subroutine area
● IRET is outside the interrupt program area
● STPE is outside the step ladder area
In the program, high-level instructions, which execute in every
scan and at the leading edge of the trigger, are programmed
Stop
to be triggered by one contact. Correct the program so that
Auto clear
the 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.
