1.6.2. HART communication
The HART communication authorizes an addressing of
devices, allowing the communication in read/write mode.
It consists in getting connection on the current loop on which
the numerical data are superimposed.
Most of the HART terminal can read these information and
send commands
The use of a DD (Device Descriptor) facilitates the interface
Man-Device. It can be uploaded on our website.
The HART output is an option. It is available only on the devices equipped with an
electronic type C, in HART configuration (H):DGi-**7-****-**H-**-***-*-C-*
OLDHAM SIMTRONICS devices under HART protocol enable the use
of all the functions available with the TLU600 via the HART terminal.
See the document D1401002 for the using of Hart terminal TLH700 (the
Detector Device Descriptor must be downloaded).
