Group Status
Any group may have an optional status that is dynamically calculated as a function of the state of its members. The status is indicated by the group's node color in the System Tree.
 | For example, a group of Devices is red if at least one device has an error, yellow if at least one device is offline, and green otherwise. |
Group Status Calculation
The group status is calculated according to the following rules:
Every time a new member is added or an existing member's Member Status Variable is changed, the Member Status Expression is evaluated for the member, generating a member status string.
All member status strings are evaluated for against the Status Table, starting from the highest status then checking lower statuses until a match is found.
Once all member statuses are calculated, the group status is set according to the highest status of all the group members.
| Let's assume that we have a group with five members. The Member Status Expression for each member is evaluated into a string value that is can be 100, 200, 300, 400 or 500 (string constants, not numbers). The example Status Table is made of these values: |
| This example illustrates how device group status is calculated by default. Default group status settings of a device group are as follows: Member Status Variable: Member Status Expression: Status Table: |
