Specific Errors

Plant SCADA driver errors can occur when a device:

• does not respond

• is disconnected

• is offline

• returns an error.

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

Generic errors are hardware errors 0-31, and are common to all protocols (for more information, see the topic Error Messages in the Reference Information section of the main Plant SCADA documentation).

Specific errors are unique to a particular driver, and may not be recognized by the hardware alarm system. The driver converts the specific errors into generic errors so they can be identified by the I/O Server. This means when a driver becomes inoperable, there is often both a specific error and a corresponding generic error.

When a hardware error occurs, 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, verify that you have Alarm Category 255 defined with a display format that includes {ErrDesc,15} {ErrPage,10}.
