Driver Errors

When a hardware error is detected, Plant SCADA generates an alarm and displays the alarm on the hardware alarm page (in the alarm description of the hardware alarm). To see the error number, you need to have Alarm Category 255 defined with a display format that includes {ErrDesc,15} {ErrPage,10}.
Several generic errors are common to many protocols. In some cases only the generic error is available, though often both the generic error and a specific error are given.
The following errors, listed in (hexadecimal) sequence, are specific to this protocol. Plant SCADA displays the error number and description for common protocol-specific errors. Uncommon errors are not contained in the Plant SCADA error database, in which case Plant SCADA only displays the error number.
You might need more information to rectify an error. This information should be in the documentation that accompanied the I/O device (or network). If, after reviewing the documentation, you cannot rectify an error, contact Technical Support for this product.
