Sequence of Events vs. Historian
Sequence of Events vs. Historian
(OP)
Would somebody mind explaining the differences between a Sequence of Events (SoE) application and a Historian application?
I am aware that some hardware vendors provide I/O cards with SoE features but i'm not exactly sure how this ties into a Sequence of Events recording application or Historian.
Thanks in advance

Per djs's comment above, I would think that a SoE routine is the similar to a first-out routine, n'est pas?

Of course now you need to test procedure on how you would shut machine down if your missing one of these signals. And also test for false triggers of same signal.
This card made life a pain in the but.
Historian is like everyone said is usually associated with a data logging function, not really acting on the signal just logging it for a trend.
