5.2.4 Status Data Collection

The host can use this capability to request selected status information. It provides for

5.3 Alarm Management

The alarm management capability enables the following functionality for host control of alarm

activity:

The host can enable, or disable, specific alarm notification.

The host can request a list of alarm texts.

The host can request a list of alarms set and enabled on the equipment.

The equipment reports both set and clear alarm events with times of alarm changes.

Each alarm has an identity (ALID), which may be in one of two states; SET or CLEAR. Each

ALID can also be ENABLED or DISABLED. The following state model determines alarm

behaviour.

The alarms implemented on the DEK printer are listed in chapter 6.
