Additional Information
Refer to A-8 Registering a Symbol Table on the CX-Designer for the procedure to register these
system-defined variables in the variable table of the CX-Designer when you connect an NS-
series PT to the NJ-series Controller.
The operation of the system-defined variables when they are used to backup data is shown below. In
the charts, “pre-execution checks” indicates processing to check whether there is a SD Memory Card in
the CPU Unit and other items before the backup starts. The value of _Card1BkupSta.Active (Active
Flag) changes to TRUE only after all of the pre-execution checks are cleared and the actual backup is
started.
