Error Simulation Function

With the CX-Programmer, it is possible to generate system errors in the virtual PLC during ladder pro-
gramming simulation. It is easy to check operation of the ladder programming an the NS-series PT
when a PLC system error occurs by generating the desired fatal or non-fatal system error using a spe-
cial operation window. For information on the debugging procedure, refer to the CX-Programmer Oper-
ation Manual (Cat. No. W446).

Error occurs
Note Unlike with an actual error, ladder execution will not stop even if a fatal error is generated using the PLC error
generation simulation function.
Additional Information
System errors can also be generated in the PLC by using a FAL(006) or FALS(007) instruction.
