DIRIS Digiware D-50 & D-70 - 548088C - SOCOMEC
The way the OID is assigned to a device (instance number) is the following:
OID = Main OID (= default 100) + ModbusAddress:
• Device with Main OID (100) is the DIRIS Digiware D-50 / D-70 display itself.
• The device with OID (1xx) is the device with the Modbus address xx.
Analog Input Object:
The DIRIS Digiware D-50 / D-70 acts as a BACnet gateway. It provides a number of Analog Input objects which may be
available from the devices compatible and connected to the DIRIS Digiware D-50 / D-70.
Whether a device supports an AI object depends on its measurement functionalities.
Ex: The OID for THD_I1 will return 0 for a DIRIS Digiware I-30 module because this parameter is not handled.
The AI object denes 25 properties. The devices compatible and connected downstream the DIRIS Digiware D-50 / D-70
support the following properties:

The way the OID is assigned to an Analog Input Object (instance number) is the following:
OID = LLMM
• with LL = Load # of the device (starting at 1).
• with MM = Index of the measurement type (see Analog Input Measurement List).
For example, Analog Input with OID 204 reects Phasis/Neutral Voltage V1 of Load 2 of corresponding device.
