Checking for Errors with System-defined Variables

The system-defined variables include an Error Status variable, which shows the error status in a hierar-
chical structure. The system determines the error status of each level by logically ORing the error status
information of the next lower level. You can read the Error Status variable from an external device
through communications. Refer to the NY-series Industrial Panel PC / Industrial Box PC Software
User's Manual (Cat. No. W558) for information on system-defined variables.
