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.

5.2.9 Host Requests Report by CEID

Step SECS Message Description

1. H -> E S6F15 W Request Event Report. The Host requests a

report for the specified CEID. In this way, the

host requests the Equipment to „pretend that

the specified CEID has occurred.

2. H <- E S6F16 The Equipment sends reports linked to that

CEID.

5.2.10 Host Requests Annotated Report by CEID

Step SECS Message Description

1. H -> E S6F17 W Request Annotated Event Report. The Host

requests a report for the specified CEID. In

this way, the host requests the Equipment to

„pretend“ that the specified CEID has

occurred.

2. H <- E S6F18 The Equipment sends annotated reports linked

to that CEID.

5.2.11 Host Requests Report by RPTID

Step

SECS Message Description

H -> E S6F19 W Request Report. The Host requests a report

for the specified RPTID.

H <- E S6F20 The Equipment sends the report.

5.2.12 Host Requests Annotated Report by RPTID

Step SECS Message Description

1. H -> E S6F21 W Request Annotated Report. The Host requests

an annotated report for the specified RPTID.

2. H <- E S6F22 The Equipment sends the annotated report.

5.2.13 Are You There

Step SECS Message Description

1. H -> E S1F1 W Are You There. The Host sends this simple

message.

2. H <- E S1F2 The Equipment reports its MDLN and

SOFTREV.
