800xA Saving Present Values as Initial Values
I am working on 800xA system. Is it possible to change initial values by pressing a button on SCADA? Can I save present values as initial values?
If this is possible, I would be appriciate for any help.
Initial Values (used when the controller is "Init" Started) ... You may be able to set the initial values using Bulk Data Manager, but this will probably not be a "One Button" push. However, with some work and the report schedular, you might possibly be able to make this a relatively easy option.
Cold Retain Values (used when the controller is "Cold" started) .... No, not to the 800xA System. You can however, automatically save Cold Retain Values to the OPC Connectivity server every few hours. You can ( and should ) enable and configure this feature in the OPC Connection Panel. Offset the collection of Cold Retain files so that you do not try to save the files on both servers in a redundnt pair at the same time. Saving Cold Retain values will typically slow or pause the OPC server for a few monents.
You can also save Cold Retain values to a CF Card in the AC800M. This saving can be triggered by a Program block, so yes you could do this from the HMI. However, your Application Program must also be installed on the CF card.
