Published Data, used for the Gateway’s OPC and Modbus outputs, falls into the following categories:
Field Device Identification Values:
Values that define the identity of the DVC2000. These include:
D MANUFACTURER (for “Fisher Controls” the value is “19”)
D DEVICE_TYPE (for a DVC2000 the value is “5”)
D DEVICE_REVISION
D HARDWARE_REVISION
D SOFTWARE_REVISION
D DEVICE_ID
D UNIVERSAL_REVISION (HART version)
D REQUEST_PREAMBLES
Variable information:
The Gateway receives updates concerning the DVC2000’s four “Dynamic Variables”. The information for any given
device variable is displayed by:
1. Dynamic Variable indicator (“PV”, “SV”, etc.)
2. The Device Variable ID number assigned to that Dynamic Variable
Dynamic Variable Device Variable ID Device Variable Name(s)
Analog Input PV 0 LOOP_CURRENT
Travel Setpoint SV 9 TRAVEL_SP
Pressure TV 2 PRESSURE
Travel QV 3 TRAVEL
Milliamp Current 245 CURRENT
Either of these choices (Dynamic Variable or Device Variable ID) can be substituted for the “#” sign in the Variable
Identifier fields below.
Variable Identifier Comments / Explanation
