Driver Errors

Plant SCADA has two kinds of protocol driver errors: generic and specific.

• Generic errors are hardware errors 0-31, which are common to many protocols.

• Specific errors are unique to a particular driver.

When a driver specific error occurs, the hardware alarm system will not recognize it. The driver converts the specific error into a generic error that can be identified by the I/O server.

This means a driver error may be represented by a specific error, and a corresponding generic error.

When a hardware error occurs, Plant SCADA generates an alarm and displays it on the hardware alarm page. To see the error number, you need to have Alarm Category 255 defined with a display format that includes {ErrDesc,15} {ErrPage,10}.

Refer to the Plant SCADA Help for more information on generic hardware errors.

See the topic OFSOPC Driver Specific Errors for information on the errors specific to the OFSOPC driver.

If you need more information to resolve an error, refer to the documentation that accompanied the I/O device (or network). If, after reviewing the documentation, you still cannot solve your problem, contact Technical Support for this product.
