driver-TuningPolicyMap
This component contains one or more TuningPolicy(ies) found in the Property Sheet of most network components. You can create multiple tuning policies under a network’s Tuning Policy Map. You can then assign one or more proxy points to a specific tuning policy.
| Property | Value | Description |
|---|---|---|
| Min Write Time | hours minutes seconds, zero (default) to infinity | Specifies the minimum amount
of time allowed between writes to writable proxy points, especially
ones that have one or more linked inputs. This provides a way to throttle
rapidly changing values so that only the last value is written. The default value (0) disables this rule causing all value changes to attempt to write. |
| Max Write Time | hours minutes seconds, zero (default) to infinity | Specifies the maximum amount
of time to wait before rewriting the value, in case nothing else has
triggered a write, to writable proxy points. Any write action resets
this timer. The default (0) disables this rule resulting in no timed rewrites. |
| Write On Start | true (default) or false | Determines a writable
proxy point’s behavior when the station starts. true initiates a write when the station first reaches a steady state. false prevents a write when the station first reaches a steady state. Note: Consider setting to false except for critical proxy points, otherwise large networks may experience
write-queue-overflow exceptions. |
| Write On Up | true (default) or false | Determines a writable
proxy point’s behavior when the point and its parent device transition
from down to up. true initiates a write when a transition from down to up occurs. false prevents a write when a transition from down to up occurs. |
| Write On Enabled | true (default) or false | Determines a
writable proxy point’s behavior when the point’s status transitions
from disabled to normal (enabled). true initiates a write when the transition occurs. false prevents a write when the transition occurs. |
| Stale Time | hours minutes seconds, zero (default) to infinity | Defines the period of time without
a successful read (indicated by a read status of {ok}) after which
a point’s value is considered to be too old to be meaningful (stale). A non-zero value causes the point to become stale (status stale) if the configured time elapses without a successful read, indicated by Read Status {ok}. The default value (zero) disables the stale timer causing points to become stale immediately when unsubscribed. |
