Device Registration Commission Commands
Landis+Gyr device commission commands can be used to “register” the device and notify the L+G head-end system that meters have been added to inventory. Device commission commands of this type have the “Registration-Only Mode” flag set to “Yes”. An Enter algorithm on the “Commission Ready” state evaluates the Registration-Only Mode of the command and if set to “Yes”, the command skips the default “Waiting for Measurement” state and is transitioned to the “Execute Completion Event” state, and an activity log entry is created.
Only the device registration request is sent to the head-end system for device commission commands of this type.
Device registration commands are typically created when new devices are added to inventory in an asset management system such as Oracle Utilities Operational Device Management.
Device Installation Commission Commands
Landis+Gyr device commission commands can be used to notify the L+G head-end system that meters have been installed or exchanged. An Enter algorithm on the “Commission Ready” state evaluates the “Is Installation Check Unnecessary” flag of the command and if set to “False”, the algorithm creates an “L+G Meter Exchange Notification” outbound communication and sends an installation notification to the head-end system.
Device Deregistration Commands
The Landis+Gyr adapter supports the Device Deregistration command (based on the D1-DeviceDeregistration business object). This command sends a communication that deregisters the device in the head-end system, and is most often used when retiring a device. The specific message sent is defined for the Device Deregistration processing role for the L+G head-end system service provider.
Device deegistration commands are typically created when devices are retired in an asset management system such as Oracle Utilities Operational Device Management.
