Application Config
The Application Config tab of System Configuration holds packet retention, update checks, the recent tag history window and scripting.
Saving changes on any System Configuration tab restarts Profinity. Refer to System Configuration for what to expect.
| Parameter | Default | Range | Description |
|---|---|---|---|
Maximum number of retained Packets |
1000 | 1 to 10000 | The number of CAN packets Profinity retains for the CAN utilities. |
Custom Update Server |
Blank (standard Prohelion update service) | - | The address of your own update server. Leave it blank to use the standard Prohelion update service. |
Update Check Interval (hours) |
24 | 1 to 168 (one week), or 0 | How often Profinity checks for updates. 0 disables scheduled checks. |
Recent tag history — local window (minutes) |
60 | 1 to 10080 | How far back dashboard bindings read from the in-memory tag buffer. |
Enable Scripting |
Off | - | In the Optional Capabilities section. Turns scripting on for the instance. |
For the recent tag history window, a dashboard binding that queries a time range starting within the window is served entirely from the in-memory tag buffer. A range that starts earlier uses the designated InfluxDB reader for the whole window, when one is configured.
Scripts run code on the host, so turning on scripting is a security decision. The Enable Scripting field is available only when the licence includes the Scripting feature (Desktop, Server, and Enterprise editions). An unlicensed instance does not include scripting.
