5.2.3 Equipment Reports Annotated

Step SECS Message Description

1. The Equipment recognizes that an event has

occurred. The Host has enabled reporting for

the {XE „CEID“}CEID, and possibly has defined

one or more Reports and linked them to the

CEID. The Equipment Constant RpType is set

to „True“, requesting Annotated reports.

2. H <- E S6F5 W Inquire. If S6F13 will be multi-block, the

Equipment first sends this Inquire to request

permission. If S6F13 is single-block, skip this

and the next step.

3. H -> E S6F6 Grant. The Host grants permission to send

multi-block event report. If {XE

„GRANT6“}GRANT6 is non-zero, this scenario

fails here, and the event data is discarded.

4. H <- E S6F13 W The Equipment sends annotated event reports

for the CEID that occurred.

5. H -> E S6F14 The Host acknowledges the report.

Note: In all other scenarios in which event reports occur, the Events or Annotated

Events are shown in abbreviated form (S6F11/S6F12 only). The complete Event Report

Scenarios are shown here.

5.2.4 Host Initiates Trace

Step SECS Message Description

1. H -> E S2F23 W The Host initiates a trace.

2. H <- E S2F24 The Equipment acknowledges the trace request.

If the data in S2F23 is not valid, the

acknowledge code in this message is non-zero

and the scenario ends. Otherwise, the following

steps are done „TOTSMP“ times, where {XE

„TOTSMP“}TOTSMP is the total number of

samples to be done.

The Equipment waits „{XE „DSPER“}DSPER“

(data sample period). While waiting, the

Equipment continues to operate normally,

responding to any SECS messages that may be

received, etc. After the wait is finished, the

values of the variable(s) to be traced are

obtained and saved. If „{XE

„REPGSZ“}REPGSZ“ samples have been

saved, or if this is the last sample, do the

following steps.

4. H <- E S6F1 W The Equipment sends trace data.

5. H -> E S6F2 If the S6F1 has its W-bit set to 1, the Host

acknowledges the trace data.

6. If this is the last sample, the Equipment

terminates this trace and the scenario ends.

Otherwise, go back to the beginning of step 3.

5.2.5 Host Terminates Trace

Assumption: The Host started a Trace report as in the above scenario.

Step SECS Message Description

1. H -> E S2F23 W The Host initiates a trace, with the same trace

ID as the currently running trace, and with {XE

„TOTSMP“}TOTSMP (number of samples) set

to „0“.

2. H <- E S2F24 The Equipment acknowledges the trace

request. If the data in S2F23 is valid, the

Equipment terminates the trace.

3. If the Equipment has saved trace data that has

not yet been sent to the Host, it discards the

saved data.

5.2.6 Host Requests Status

Step SECS Message Description

1. H -> E S1F3 W Discrete Variable Request. The Host requests

the VIDs of interest.

2. H <- E S1F4 The Equipment sends the Variable values.

5.2.7 Host Defines Limits{XE "Limits Monitoring"}

Step SECS Message Description

1. H -> E S2F45 W Host defines new variable limits attributes.

2. H <- E S2F46 Equipment accepts new limits definitions, and

responds with {XE „VLAACK“}VLAACK =

0x00.

5.2.8 Host Queries Defined Limits{XE "Limits Monitoring"}

Step

SECS Message Description

H -> E S2F47 W Host requests listing of defined limits. This

request may be for limits of individual

variables listed in this message, or if this

message is an empty list, all limits will be

replied.

H <- E S2F48

{XE „VLAACK“}Equipment sends limits values

as required.
