Access System Registers in Cscape IEC

[pbenoit]

Does anyone know how to access the system registers (i.e. First Scan bit) in IEC editor version of Cscape 9.3? The system registers were pre-configured in the Ladder Logic only version of Cscape, but its not obvious or detailed in the help files on how to access these same registers in the IEC version.

Thanks.

Never mind, just figured out you have to define your own variable in the IEC version and use the proper system register in the Tag Field. Also you have to pay attention to the number of leading zeros. For example %S001 is not auto-corrected to %S01 for you.
