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.

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.

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.

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.

Step
SECS Message Description
1.
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.
2.
H <- E S2F48 Equipment sends limits values as required.

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.

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