Error contents and steps to take
1
CPU hardware error 1
Stop
2
CPU hardware error 2
Stop
There may be a hardware problem. Please contact your dealer.
3
I/O bus power supply
error (including "no
end cover")
Stop
Error in the I/O bus part is probable, such that the end unit has
not been attached. Double-check the attachment status of
units.
4
Unit attachment limit
exceeded
Stop
is probable that the unit attachment limit has been exceeded.
Double-check the configuration.
20 Syntax
error
Stop
Auto clear
A program with a syntax error has been written. Switch to the
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
duplicated output to “enable” in the CPU configuration.
21 Duplicated
use
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.
22 Not
paired
Stop
Auto clear
Applicable instructions and cases are as follows.
• MC and MCE are not paired.
• 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.
24
Program area error
Stop
Auto clear
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.
• EDPB is outside the blank area.
• 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.
25
High-level instruction
execution
combination error
Stop
Auto clear
In the program, high-level instructions, which execute in every
scan and at the leading edge of the trigger, are programmed to
be triggered by one contact. Correct the program so that the
high-level instructions executed in every scan and only at the
leading edge are triggered separately.
27
Compile memory full
error
Stop
Auto clear
The program is too large to compile in the program memory.
Switch to the PROG. mode and reduce the total number of
steps for the program.
(Note) For errors where "Auto clear" is indicated in the 'Operation' column, error clearance is executed when power
supply is cut off, or when the unit is set to the RUN mode again after the status has been corrected.
