Siemens HART Modem with USB Interface
Siemens HART is a widely used communication standard for field devices. HART devices are specified by the FieldComm Group.
The HART standard expands the analog 4 to 20 mA signal to modulated, industry-tested, digital signal transmission.
Devices can be connected in different ways:
- Through the distributed I/O- SIMATIC ET 200M, ET 200SP- SIMATIC ET 200iSP with the HART modules or with analog modules 4 to 20 mA and HART Handheld Communicator,
- via a HART modem with which a point-to-point connection between the PC or Engineering System and the HART device can be established
- via HART multiplexers which are contained in the HART server of the HCF.
- Tried-and-tested analog measured value transmission
- Simultaneous digital communication with bidirectional data transfer
- Possibility to transfer multiple measured variables from a field device (e.g. diagnostics, maintenance and process information)
- Connection to higher-level systems such as PROFIBUS DP.
- Easy installation and commissioning
- Manufacturer-neutral operation of all HART devices through standardized parameter sets
- HART field devices described by HART DLL are integrated in SIMATIC PDM via the Fieldcomm catalog. HART-DD (Device Description) in SIMATIC PDM standardized, manufacturerneutral and very widely used. Additional field devices are integrated in SIMATIC PDM via EDD (Electronic Device Description)
- Simple operation and commissioning of field devices, even in usage locations that are difficult to access
- Advanced diagnostics, evaluating and logging functions
