The device status includes alarm status and diagnostic information such as input status and calculation status.<br />
The <strong>Scanner</strong> <strong>2000</strong> provides 16 user-configurable alarms designated as <strong>Flow</strong> Run Alarms. The user can assign<br />
the alarms to any parameter in the holding register map. Alarms can be defined as low alarms or high alarms.<br />
For details on configuring <strong>Flow</strong> Run Alarms, see Section 3 of the ModWorX Pro Software User Manual. The<br />
current status of the alarms can be obtained by reading the <strong>Flow</strong> Run Alarm registers in the device status map.<br />
A bit value of 1 indicates an alarm condition. Also contained in the device status map are diagnostic registers.<br />
The bits in these registers provide system status for inputs (under range, above range or failed), calculation<br />
status (for confirming whether the flow run is working properly) and details regarding the health of the MVT.<br />
