Hart Function - Siemens SIMATIC ET 200SP Manual

HART function

The HART function is available in the following conditions:
● The I/O module AI-DI 16/DQ16x24VDC HART HA is configured in mixed mode.
● The relevant channel is configured as an analog input.
Definition
"HART" stands for "Highway Addressable Remote Transducer".
Using the HART function, you can exchange data between the I/O module and the connected
field devices. The HART protocol is generally accepted as a standard protocol for
communication with intelligent field devices: HART is a registered trademark of the HART
Communication Foundation (HCF), which owns all the rights to the HART protocol. You can
find detailed information about HART in the HART specification.
Advantages of HART
Using the AI-DI 16/DQ16x24VDC HART HA offers the following benefits:
● Connection compatibility with standard analog modules: 4 to 20 mA current loop
● Additional digital communication using the HART protocol
● Numerous field devices with HART functions are in use
● The I/O module enables the use of HART devices in an IO device based on the ET 200SP
HA.
Use in the system
The I/O module is used in an IO device based on the ET 200SP HA.
You can connect a HART field device to each channel (monodrop mode).
The I/O module operates as the HART master, the field devices as HART slaves.
The maximum 16 channels communicate in parallel.
