6.2 HART® Interface
6.2.1 Introduction
TELEDYNE OLDHAM SIMTRONICS GD10P/PE detector supports HART® version 7.
For proper operation between GD10P/PE and the HART® communicator, a dedicated Device
Descriptor (DD) should be loaded onto the communicator. If such DD is not present, the
communicator will offer a generic interface, and the list of available functions may be limited.
The proper DD for GD10P/PE can be downloaded from HART® Foundation website
https://www.fieldcommgroup.org/registered-products
. (product name:GD10P).
The loading of the DD onto a specific communicator must be done according to the relevant user
guide for that communicator.
The loss of HART communication is not related to safety.
6.2.2 Connection
For access to the detectors HART® features, connect an industry standard HART® communicator
as shown in the following figures depending on the type of analog interface (source or sink).
Note that for the HART® communication to work properly, a minimum loop resistance is required
in the current loop. The actual value of the serial resistance in the diagrams below may vary
depending on the rest of the resistance in the loop.
