Our control panel is a stand alone unit (isn't tied into a higher network like FT View SE). I'm currently investigating Historian ME: -Can only be used with ControlLogix -Requires additional (costly) hardware -Models only include 1-2 Gb capacity -Use of DataLink required So far this approach is nice: -I can choose my SD card size -Doesn't require extra hardware -Can use this method for both compact AND control logix. From there the technician can plug the USB thumb drive into their computer where we have an excell macro process the data into system reports. I then use ActiveX object 'Program Launcher' to run a batch file that copies the files from the SD card to a USB thumb drive that a technician can plug into our panel. Up until now I have been using the ActiveX object 'DataStore Plus' to periodically log tag data (max 100 floats, 50 string tags) to an SD card on the PanelView.
