Error Messages

Plant SCADA has two kinds of protocol driver errors:

• generic

• driver-specific

Generic errors are hardware errors 0-31, and are common to every protocol.

Drivers have their own specific errors, which can be unique and therefore cannot be recognized by the hardware alarm system. The drivers convert their specific errors into generic errors that can be identified by the I/O Server.

For example, when a driver becomes inoperative, there is often both a driver-specific error and a corresponding generic error.

Note: For reference information related to the implementation of device drivers, including driver alert messages, please refer to the Driver Reference Help.
