Supervision of HART instrument Appendix A Operating with HART DTMs
148 3BSE027630-600 B
The DTM for the AI895 and AO895 have a Service application with different
functions for the module (For AI895, see Service on page 93; and for AO895, see
Service on page 110). The service function Perform master reset will reset the
HART functionality in the module and a new scan for HART instruments on every
channel will be done.
Supervision of HART instrument
The AI895 or AO895 module has an supervision option (see Scan enabled).
This option can be turned on or off from the DTM, Service application with the
service functions “Enable scan” and “Disable scan”.
This option only applies for HART instrument that already has been confirmed
by the module. This option will not discover any newly added HART
instruments. It only supervises the ones in an internal list.
