5.2.1 Monitoring tree structure

Monitoring object

An object that you monitor using the Central Scope.

A monitoring condition can be set for a monitoring object to change its icon to error status or other status under certain conditions.

The icon status changes when a JP1 event related to the object is received by JP1/IM - Manager and is found to match the set monitoring condition.

Monitoring group

A group of monitoring objects.

A monitoring group can contain monitoring objects and/or other monitoring groups.

When the icon status of a lower-level object or group changes on receipt of a JP1 event, the icon status of the higher-level monitoring group containing that object or group also changes.

Virtual root node

Appears only when the monitoring range settings are enabled for the monitoring tree. For details, see 5.4.3 Setting the monitoring range of a monitoring tree.

For example, if the JP1 user jp1ope logs in to JP1/IM - Manager (Central Scope) while the monitoring range settings are enabled, the virtual root node will appear at the top of the monitoring tree as shown in the figure below.

As shown in the figure, the virtual root node is identified by an icon in the shape of a person. The name of the virtual root node is that of the JP1 user currently logged in to JP1/IM - Manager (Central Scope).

Unlike a monitoring object or monitoring group, the information in a virtual root node cannot be edited (in the Properties window). Neither can you change the node status or perform any other direct operations on the virtual root node. (Its status changes accordingly when the status of a monitoring node below it changes, but you cannot change the virtual root node status directly. To change its status, you must change the status of a lower-level monitoring node.)
