I have questions about using multiple tags' value (at same timestamp) to generate values of multiple tags.
(1) We get tag_src1 and tag_src2 from UFL to PI DA server, so both of the tags have a series of same timestamps and different values.
(2) We want to us PI AF... to generate values of additional tags. e.g. output to tag_dest_1 as (tag_src1 + tag_src2) where the exact timestamp's values' addition to tag_dest_1 with the same timestamp. Similarly another operation (tag_sc1 - tag_sc2) to tag_dest_2. Is it possible to use PI AF and Analysis to make it ?
I'm not sure is that when we perform operation by tag's trigger, do we have problems of ensuring both tag_src1 and tag_src2 at exact timestamp will have values already from sources at that timestamp ?
If this tag's frequency is one points every 100 ms. Will that be another issue ?
