In order for most items to be active within the Geo SCADA Expert system and for the Geo SCADA Expert server to communicate with those items that have comms, you need to ensure that the item is In Service (active). You also need to ensure that the item has valid, saved, configuration (an item that has invalid configuration behaves as if it is out of service, with its Quality status attribute indicating the reason for that behavior—for more information, see Checking for Invalid Configuration.)
Use the In Service check box on the item’s configuration Form to specify whether that item is In Service.
Select the check box for the item to be active (providing that the item has valid, saved, configuration). By default, most items are not In Service when they are first created.
Clear the check box for the item to be inactive (out of service). (Be aware that where a database item has dependents, if you take that item out of service, its dependents also become out of service. For instance, if you take an outstation out of service, its points, pulse actions and other dependents also become out of service.)
The Quality status attribute of an item that has valid configuration but is not in service indicates that the item is ‘Out of Service’.
Some items, such as Internal Points
Items that are in Group Templates and unconverted Abstract Items are always deemed out of service, as they are not ‘live’ (see Group Templates and Group Instances).
On some drivers that support the uploading or importing of configuration, the In Service check box might provide additional functionality to that documented in this topic. Where this applies, the driver-specific guides provide information about such functionality.
