The AI object processes data from a physical analog input point that resides on a field device and presents the data to the Metasys system in a consistent format that is independent of the source. Analog Input Objects appear under the field device object in the All Items navigation tree.
When the source of the data is an analog input in an N2 controller on the N2 Trunk, a Network Communication Module (NCM) on an integrated N1 network, or an integrated BACnet device, the Analog Input Object exchanges data with the native analog object in the source to synchronize attribute data that are common to both. The source is identified under the hardware tab of the Analog Input Object.
