Calculation Scheduler
Similar to "Scheduling Blocks for Calculations". I have a calculation that runs once per day. The calculated values need to be editable via the API or Data Entry Widget. If the calculation is running, the tag is logged and cannot be edited until the calculation is turned off.
It would be very beneficial to only run this service in the early hours of the morning so that we can make edits throughout the business day without having an admin turn off the service.

Hi ,
You could potentially work around this when using the API by using a SaF service that is remote from the Calculation service. The problem only arises when duplicate tags originate from the same SaF as tags must be unique. If the API uses a remote SaF service, you wouldn't have to stop Calculations.
The Axiom Data Entry workaround would be more involved as it would require you to install the Axiom service remote from the Historian/Calc server. You would need to install a local SaF on the Axiom server which it would use to write data back to the Historian.
