5.2.3 Trace Data Collection

This capability enables reports to be sent at fixed intervals. This is achieved as follows:

The host initialises a trace by sending S2F23. This message defines the trace

report including, time interval (DSPER), total number of samples (TOTSMP),

the number of samples per trace report (REPGSZ) and a list of data to report

(SVID's). The host also provides an identity for the trace (TRID) so that it can

later differentiate between simultaneous traces.

The total number of reports sent will be TOTSMP/ REPGSZ unless the host

sends a new S2F13 with the same TRID, when the trace replaced by a new one.

The host can end a trace by sending the same TRID, with TOTSMP = 0.

For a detailed example, of trace data collection, refer to note A.4 of SEMI E30 standard.

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:

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)

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.
