4200
No NEXT instruction was executed
following the execution of a FOR
instruction.
Alternatively, there are fewer NEXT
instructions than FOR instructions.
Read the common information of the
error using the peripheral device, check
error step corresponding to its
numerical value (program error
location), and correct the problem.
4201
A NEXT instruction was executed
although no FOR instruction has been
executed.
Alternatively, there are more NEXT
instructions than FOR instructions.
4202
More than 16 nesting levels are
programmed.
Keep nesting levels at 16 or under.
4203
A BREAK instruction was executed
although no FOR instruction has been
executed prior to that.
Read the common information of the
error using the peripheral device, check
error step corresponding to its
numerical value (program error
location), and correct the problem.
4210
The CALL instruction is executed, but
there is no subroutine at the specified
pointer.
4211
There was no RET instruction in the
executed subroutine program.
4212
The RET instruction exists before the
FEND instruction of the main routine
program.
4213
More than 16 nesting levels are
programmed.
Keep nesting levels at 16 or under.
4220
Though an interrupt input occurred, the
corresponding interrupt pointer does not
exist.
Read the common information of the
error using the peripheral device, check
error step corresponding to its
numerical value (program error
location), and correct the problem.
4221
An IRET instruction does not exist in the
executed interrupt program.
4223
The IRET instruction exists before the
FEND instruction of the main routine
program.
• The IRET instruction was executed in
the fixed scan execution type
program.
• The STOP instruction was executed
in the fixed scan execution type
program.
QnU
4225
The interrupt pointer for the module
mounted on the extension base unit is
set in the redundant system.
Delete the setting of interrupt pointer for
the module mounted on the extension
base unit, since it cannot be used.
