The Host requests the Equipment to initiate a time driven trace operation.
The Equipment will send trace data using S6F1.
If TRID in S2F23 matches TRID of an existing trace, the existing trace operation is
canceled, and replaced by the new one.
Up to four (4) separate TRIDs can be in operation simultaneously.
Within DSPER, must be a valid hour/minute/second format ( hh 0-23, mm 0-59, ss
0-59), and cannot be 000000. The practical minimum value of DSPER is application
dependent.
The Equipment will send the first S6F1 at one time period (DSPER * REPGSZ) after
receiving S2F23.
If TOTSMP is zero, then S2F23 is a request to cancel an existing trace. Any trace
with the specified TRID is canceled.
REPGSZ minimum value is 1. REPGSZ may not be so large that S6F1 would be a
multi-block message. Typical value is 1.
Several SVIDs can be specified if desired. You must not specify so many SVIDs
that S6F1 becomes a multi-block message.
Normally, only Variables of class SV are used in this message. However, any VID
of class DV, EC, or SV can be used.
