Hi,

Several record types also support a DTYP of "Async Soft Channel” which can also be used for CA put callback. So you could have a dfanout or seq record, with PP output links, process a set of records that all have DTYP="Async Soft Channel”.

Although, the sseq tends to be my go-to record for this type of application.

Cheers,
Matt

Any set of consecutive output links can be done in parallel, and then waited for before going on to the next link.  The WAITn fields control this.  For example, to execute LNK2 and LNK3 in parallel, set WAIT2 to "After 3", and set WAIT3 to "Wait"
