# Time Based (Daily) Protocols
This page pertains exclusively to time-based protocols. For measure round protocols, see the measure round page.
Time based protocols (currently only daily ones are implemented) need to be confirmed and approved in certain intervals, so that any atypical measurements or erroneous behaviours on measure points are being noticed. You could then, for instance, comment to point out the anomaly or remeasure the values manually.
MDA allows you to generate protocol definitions, after which protocols will then be automatically generated. Those can then be reviewed by authorized users, who can sign their review with a digital signature proving their involvement. You can also create comments about protocols, for instance mentioning faults or abnormalies.
If a definition is in place, MDA will automatically parse time series data and make them available as protocols on the protocol search page.
# Protocol Definitions
In order to have time-based protocols generated, it is first necessary to formulate a definition to which the protocols should adhere. Protocol definitions can be defined in the admin configuration interface.
Each definition consists of multiple components:
- Name: Simply the identifier given to a protocol. Does not have to be unique, although it is recommended to give them descriptive names.
- Measure Point: The measure point where the protocols should be generated. Only one measure point can be set for a protocol definition.
- Protocol Members: (See below The list of time series to be observed as part of the protocol. Those should all be part of the subtree extending from that measure point.
- Active From: A timestamp which marks the start point after which protocols should be generated.
- Active Until: An optional timestamp after which this particular protocol definition is no longer being used.
# Protocol Members
The time series part of the protocol definitions are also called protocol members. In addition to a reference to the time series itself, a few other parameters are stored:
- Position: Starting with 1 for the first element, this simply indicates when the time series appears in the protocol. Can be changed in the definition configuration.
- Min/Max Difference Limit: If the difference between the time series' measured maximum and minimum in the timeframe is exceeding this value, then an additional warning is denoted for a protocol. Optional.
- TISGraph URL: An optional link to the TISGraph chart for this time series. When set, users will be able to open it on the daily protocol page.
