LDAP Network view

This tab shows standard properties for the LDAP Network driver.

To access this tab, navigate to Controller (System) Setup > Remote Devices > Remote Drivers and double-click your LDAP network device driver row in the Remote Drivers view.

The view title, Ldap Network in this example (this name may be different in your system), displays in the top left corner above the Save and Drivers links.

LDAP Network tab

This tab turns the LDAP network on and off and reports network status. In addition to the standard properties (Status, Enabled, Fault Cause, Health, and Alarm Source Info), these properties support the Ldap Network.

Property Value Description
Ping Monitor additional properties Links to a set of properties for configuring the ping monitor (the mechanism for confirming the health of devices on the network).

Refer to Ping Monitor.

Tuning Policies additional properties Links to a set of properties for configuring network tuning policies (rules for write and read requests from polling).

Refer to Tuning Policy.

Ping Monitor

Property Value Description
Ping Enabled true (default) or false Turns the use of the ping monitor on and off.
Ping Frequency hours minutes seconds Defines how frequently the system pings the server.
Alarm On Failure true (default) or false Controls whether or not the system issues an alarm when a ping fails.
Startup Alarm Delay hours minutes seconds Defines a waiting period before the system issues an alarm when the ping fails.
Num Retries Until Ping Fail number Defines the number of retries until ping is successful.

Tuning Policy

A network’s tuning policy defines rules for when to write to a writeable proxy point, and how to determine the freshness of a read request from polling.

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 Enabled true (default) or false
When its status transitions from disabled to enabled, defines a writeable proxy point’s behavior.

true initiates a write when the transition occurs.

false prevents a write when the transition occurs.

Write On Start true (default) or false
At station startup, defines a writeable proxy point’s behavior.

true initiates a write when the station first reaches a steady state.

false prevents a write when the station first reaches a steady state.

Write On Up true (default) or false
When the point and its parent device transition from down to up, defines a writeable proxy point’s behavior.

true initiates a write when the transition occurs.

false prevents a write when the transition occurs.

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.
