5.2.4 Status Data Collection

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

synchronisation of equipment status.

To obtain a status report, the host sends a request with a list of specific SVID's. The

equipment will respond with a list of status values.

Scenarios:

Equipment status variable report request:

Comments Host Equipment Comments

Host requests report of selected status

values.

S1F3 -->

<-- S1F4 Equipment replies with requested data

Equipment status variable namelist request:

Comments Host Equipment Comments

Host requests equipment to identify

selected status values.

S1F11 -->

<-- S1F12 Equipment replies with requested status variable

descriptions.

5.2.5 On-Line Identification

Using this capability, the host can confirm the presence of the equipment. The

equipment will send its identity MDLN and software revision SOFTREV in response to

a request from the host.

Scenarios:

On-Line data report: (Host to equipment)

Comments Host Equipment Comments

Host requests On-Line data S1F1 -->

<-- S1F2 Equipment replies MDLN & SOFTREV

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.
