4. In the Source field, choose the appropriate Enraf device type (Enraf 811, 813, etc.). In case you
cannot find a suitable Enraf device you should choose Enraf TOI B .
5. Select the Field Port that the device is connected to. Ensure that the port is equipped with an Enraf
modem. In the standard configuration there are six field bus ports available for the Rosemount 2460
System Hub. See
“Connecting to a Rosemount 2460 System Hub” on page 30 for more information.
6. Enter the address of the Enraf servo gauge into the Level Device Address field. Each field device has
its own unique address in the range 00-99.
7. In the Temp Device Address field, enter the level device address in case the temperature elements
are connected to the servo gauge. If the temperature elements are connected to an external
temperature transmitter, enter the address of this device. Entering a temperature device address will
ensure that the 2460 includes
Average Temperature when sending requests for measurement data.
8. In the Number of Temp Elements field, enter “0” elements in case only Average Temperature is
required. If you would like to retrieve individual temperature values for each spot element, you have
to enter the total number of connected elements. In case you don’t need to monitor values for
individual temperature elements you should set this parameter to “0” in order to avoid unnecessary
load on the field bus.
9. Select the Auxiliary Inputs that are used for the device. Vapor Pressure (VP), Middle Pressure (MP),
Liquid Pressure (LP), Free Water Level (FWL), and Observed Density (UIn1) can be configured for Enraf
devices. See
Table C-1 on page 173 for a list of available Auxiliary Inputs.
