Maxpro Network tab

This view configures an Maxpro Network, which is primarily used for reader devices.

Figure 213. Maxpro Network tab

You access this tab from the main menu by clicking Controller Setup > Remote Devices > Remote Drivers followed by double-clicking the Maxpro Network row in the table.

Properties

In addition to the common Status, Enabled, Fault Cause and Health properties, this tab includes these properties.

Property	Value	Description
Alarm Source Info	additional properties	Contains a set of properties for configuring and routing alarms when this component is the alarm source.
Monitor	additional properties	Configures ping properties. Refer to Monitor properties.
Tuning Policies	additional properties	Configures network rules for evaluating both write requests to writable proxy points as well as the acceptable freshness of read requests.Refer to Tuning Policy (later in this topic).
Fox Video Stream Preferred	`true` or `false` (default)

Monitor properties

Property	Value	Description
Ping Enabled	`true` (default) or `false`	Turns the monitor ping on and off. `true` each network device receives a ping, as needed. `false` no network device receives a ping. Device status remains as recorded the last time this property was `true`. Recommendation: leave `Ping Enabled` as `true` in almost all cases.
Ping Frequency	hours:minutes:seconds	Specifies the interval between periodic pings of all devices. Typical default value is every 5 minutes (05m 00s), you can adjust differently if needed.
Alarm On Failure	`true` (default) or `false`	Controls the recording of ping failure alarms. If `true`, the system records an alarm in the station’s AlarmHistory upon each ping-detected device event (“down” or subsequent “up”). If `false`, the system ignores and does not record device “down” and “up” events in the station’s AlarmHistory.
Startup Alarm Delay	hours:minutes:seconds	Specifies the period a station must wait after restarting before device “down” or “up” alarms are generated. Applies only if the Monitor’s property `Alarm On Failure` is true.

Tuning Policy

During polling, the system uses the network driver’s tuning policy to evaluate both write requests and the acceptability (freshness) of read requests.

Property	Value	Description
Min Write Time	hours minutes seconds	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	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.
Stale Time	hours minutes seconds; defaults to 0 (zero)	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.

Property

Value

Description

Min Write Time

hours minutes seconds

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

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.

Stale Time

hours minutes seconds; defaults to 0 (zero)

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.
