4210
[CAN'T EXECUTE(P)]
The pointer specified in the instruction does not
exist.
■Collateral information
• Common information: Program error location
• Individual information: -
■Diagnostic timing
• When instruction executed
Read common information of the error using
the programming tool to identify the numeric
value (program error location). Check the
error step corresponding to the value, and
correct it as necessary.
RUN: Off
ERR.:Flashing
CPU Status:Stop
QCPU
LCPU
4211
[CAN'T EXECUTE(P)]
There was no RET instruction in the executed
subroutine program.
■Collateral information
• Common information: Program error location
• Individual information: -
■Diagnostic timing
• When instruction executed
Read common information of the error using
the programming tool to identify the numeric
value (program error location). Check the
error step corresponding to the value, and
correct it as necessary.
RUN: Off
ERR.:Flashing
CPU Status:Stop
QCPU
LCPU
4212
[CAN'T EXECUTE(P)]
• The RET instruction exists before the FEND
instruction of the main routine program.
• The RET instruction is executed before the
NEXT instruction is executed in the executed
subroutine program.
■Collateral information
• Common information: Program error location
• Individual information: -
■Diagnostic timing
• When instruction executed
Read common information of the error using
the programming tool to identify the numeric
value (program error location). Check the
error step corresponding to the value, and
correct it as necessary.
RUN: Off
ERR.:Flashing
CPU Status:Stop
QCPU
LCPU
4213
[CAN'T EXECUTE(P)]
More than 16 nesting levels of the CALL
instruction are programmed.
■Collateral information
• Common information: Program error location
• Individual information: -
■Diagnostic timing
• When instruction executed
Keep nesting levels at 16 or under.
RUN: Off
ERR.:Flashing
CPU Status:Stop
QCPU
LCPU
4220
[CAN'T EXECUTE(I)]
Though an interrupt input occurred, the
corresponding interrupt pointer does not exist.
■Collateral information
• Common information: -
• Individual information: -
■Diagnostic timing
• When instruction executed
Check that the interrupt pointer No. set in
parameter exists in the program.
RUN: Off
ERR.:Flashing
CPU Status:Stop
QCPU
LCPU
4221
[CAN'T EXECUTE(I)]
An IRET instruction does not exist in the executed
interrupt program.
■Collateral information
• Common information: Program error location
•
Individual information: -
■Diagnostic timing
• When instruction executed
Read common information of the error using
the programming tool to identify the numeric
value (program error location). Check the
error step corresponding to the value, and
correct it as necessary.
