What is the difference between setting up a tag using the historian in the database manager to set the compression vrs the iHistorian Administrator? I have read several postings for logging a digital tag only when the value changes. As of now I am getting the same results as others in that I am logging data every second. I have tried various combinations of deadband values, times, etc. I have read the unsolicited poll does not work in iFix Collector, etc. I am using Proficy Historian 4.5 and several of the posts refer to earlier versions. These are older posts and was wondering has this ever been figured out? Thanks in advance. :confused:
