Hi,
We have Honeywell TPS system (R680), currently we have process tags historized in PHD & History module. We are planning to remove the process tags configured in History module & start effectively using the PHD tags for panel operators monitoring purpose. Purpose is to reduce the LCN network load.
I still believe that the important process tags needs to be historized in History module as well, because of the fact that there is a time delay (< 60 secs) for PHD tags.
Can any one summarize the advantages of historized process tags in History module over PHD (plant historian database) for panel operators monitoring purpose.
regards,
