Multi CPU Errors (A)
I - 61
A01 MULTI CPU ERROR 4201
Details
- A NEXT instruction was executed although no FOR instruction has been executed.
Alternatively, there are more NEXT instructions than FOR instructions.
Remedy
- Read the common information of the error using a programming tool, check error step cor-
responding to its numerical value (program error location) and correct the problem.
A01 MULTI CPU ERROR 4202
Details
- More than 16 nesting levels are programmed for FOR instructions.
Remedy
- Keep nesting levels at 16 or under.
A01 MULTI CPU ERROR 4203
Details
- A BREAK instruction was executed although no FOR instruction has been executed prior to
that.
Remedy
- Read the common information of the error using a programming tool, check error step cor-
responding to its numerical value (program error location), and correct the problem.
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 cor-
responding 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 cor-
responding 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 cor-
responding 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 pro-
gram.
- Read the common information of the error using a programming tool, check error step cor-
responding 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 cor-
responding 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 cor-
responding to its numerical value (program error location), and correct the problem.
A01 MULTI CPU ERROR 4231
Details
- The number of IX and IXEND instructions is not equal.
Remedy
- Read the common information of the error using a programming tool, check error step cor-
responding to its numerical value (program error location), and correct the problem.
A01 MULTI CPU ERROR 4350
Details
An incorrect CPU module was designated by the exclusive instruction for multi-CPUs high-
speed communication set in the program.
- The designated module has already been reserved.
- The designated module has not been mounted.
- 'Head I/O No. of target CPU module divided by 16' (n1) is not within 3E0H to 3E3H.
- The designated CPU module cannot execute the instruction.
- The instruction was executed in the single CPU system.
- The designated module is the host CPU module.
Remedy
- Read the common information of the error using a programming tool, check error step cor-
responding to its numerical value (program error location), and correct the problem.
