Appendix 7.10 Multi CPU Errors (A)
A01 MULTI CPU ERROR 4210
Details
- The CALL instruction is executed, but there is no subroutine at the specified pointer.
Remedy
- Read the common information of the error using a programming tool, check error step
corresponding to its numerical value (program error location), and correct the problem.
A01 MULTI CPU ERROR 4211
Details
- There was no RET instruction in the executed subroutine program.
Remedy
- Read the common information of the error using a programming tool, check error step
corresponding to its numerical value (program error location), and correct the problem.
A01 MULTI CPU ERROR 4212
Details
- The RET instruction was before the FEND instruction in the main program.
Remedy
- Read the common information of the error using a programming tool, check error step
corresponding to its numerical value (program error location), and correct the problem.
A01 MULTI CPU ERROR 4213
Details
- More than 16 nesting levels are programmed for CALL instructions.
Remedy
- Keep nesting levels at 16 or under.
A01 MULTI CPU ERROR 4220
Details
- Though an interrupt input occurred, the corresponding interrupt pointer does not exist.
Remedy
- Check whether the interrupt pointer No., specified in the parameter setting, exists in the
program.
- Read the common information of the error using a programming tool, check error step
corresponding to its numerical value (program error location), and correct the problem.
A01 MULTI CPU ERROR 4221
Details
- An IRET instruction does not exist in the executed interrupt program.
Remedy
- Read the common information of the error using a programming tool, check error step
corresponding to its numerical value (program error location), and correct the problem.
A01 MULTI CPU ERROR 4223
Details
- An IRET instruction exists before the FEND instruction of the main program.
Remedy
- Read the common information of the error using a programming tool, check error step
corresponding to its numerical value (program error location), and correct the problem.
