HART applications
System environment for the use of HART
To use an intelligent field device with HART functionality, you require the following system
environment:
● 4 to 20 mA current loop
● Connecting measuring transmitters to the I/O module
HART parameter assignment tool "Client":
You can assign the HART parameters using an external handheld operating device (HART
Handheld) or a HART configuration tool (PDM). Both assume the function of a "client":
The parameter assignment tool affects the entire I/O module; the HART handheld is connected
in parallel to the field device.
PDM (Process Device Manager) is available standalone or integrated in STEP 7 HW Config.
In the latter case, PDM is opened from HW Config.
HART system integration:
The I/O module takes on the function of a "master" by receiving commands from the HART
parameter assignment tool, for example, forwarding them to the smart field device and sending
back the responses. The interface of the I/O module is made up of data records that are
transmitted internally via the ET 200SP HA IO device between IM and I/O module. The data
records must be created and interpreted by the client.
