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 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 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

TOTSMP is the total number of samples to be

done.

3. The Equipment waits „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 „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

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

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 VLAACK = 0x00.

5.2.8 Host Queries Defined Limits

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 Equipment sends limits values as required.
