We have an application where data (6 temperatures per machine for 4 machines) needs to be stored only when a cleaning & sterilization takes place on the machine.
The 4 machines are all controlled by SLC5/01's with an existing DH-485 network. Of course there are other control options, but we'd like to work with the existing control system versus replacing it.
The data needs to be accessible not by selecting a time and signal, but based on an event (ie select '2009-06-03 13:17 Line A Cleaning' in a drop-down menu, not select these tags and select this time range in a historical trend display).
Then the data display needs to mimic as closely as possible a chart-recorder printout since that is what the operators and QC folks are used to looking at. The data would also need to be able to print cleanly.
Any thoughts? Thanks.
