HART Communication Function

This function enables the A/D converter module to communicate with HART
In addition, using FDT frame application and DTM allows the user to set up the external devices via the A/D converter module.
In the HART communication, an analog signal of 4 to 20mADC is superimposed on a digital signal to transmit various
information to connected external devices.
(1)
(1) Set parameters of a HART-enabled device or communication path using CommDTM and Device DTM from FDT frame application. The set parameters are
written to the HART-enabled device.
(2) Superimpose an analog signal of 4 to 20mADC on HART-enabled device information or HART command between the A/D converter module and the HART-
enabled device and send/receive the information.
