Using HART
System environment for using HART
To operate an intelligent field device with HART functionality, you require the following system
environment:
Current loop 4 - 20 mA via the analog electronic modules: 4 AI I 2WIRE HART,
4 AI I 4WIRE HART or 4AO I HART.
The HART analog module takes over the function of a "master" by receiving the commands
from the HART parameter assignment tool, passing them on to the smart field device and then
returning the reply messages. The interface of the HART analog module is represented by
data records that are transferred via the I/O bus. These data records are generated or
interpreted by the HART parameter assignment tool (SIMATIC PDM).
The analog values are entered in the process input and output image in 16-bit format and with
up to 4 IEEE tags (master or auxiliary tags).
