Field Device Integration

Communication and Software

Unique consistency 

Starting with the development of our products and systems, the unique consistency is a core element of our company philosophy. We offer a comprehensive product portfolio ranging from manufacturer independent configuration tools, devices with fieldbus communication to wireless solutions. 

Fieldbus Communication

Our process instruments support all major industry standards for modern fieldbus communication, e. g. HART®, PROFIBUS, FOUNDATION FIELDBUS or MODBUS, allowing optimal integration into the overall facility.

HART is a widely used communication standard for field devices. The HART-Standard expands the analog 4- bis 20-mA signal into a modulated, industry-standard digital HART signal.


The advantage is the combination of field-tested analog measured value transmission and simultaneous digital communication with bi-directional, acyclic transmission, making it possible to transfer diagnostic, maintenance and process information from field devices to higher-level systems. Standardized sets of parameters can be used for cross-vendor operation of all HART devices.


HART Device Descriptions (EDD) are used to integrate HART devices in SIMATIC PDM ensuring easy operation and commissioning of field devices even in hard-to-reach locations.



Success factor wireless communication

Wireless solutions offer far more benefits than just the elimination of cabling and installation costs. Users also profit from significantly faster commissioning and more efficient maintenance, as well as greater flexibility and mobility. And wireless technology ensures improvement of production quality and safety in plants. In the end, all these advantages add up to greater overall plant availability.

PROFIBUS is a universal, open fieldbus which permits both

  • fast communication with intelligent, distributed I/O devices (PROFIBUS with DP system) as well as 
  • communication and simultaneous powering for transmitters and actuators (2-wire powered even called MBP Manchester Bus Protocoll).

In addition to the enormous savings resulting from the reduction in cabling and input/output hardware, the significantly greater amount of information associated with digital data transmission implies significant cost advantages for plant operation and maintenance.

Foundation Fieldbus is an open protocol designed to allow bidirectional communications to field instruments.


This communication enables:

  • asset management
  • advanced diagnostics
  • flexible expandability based on Device Description
  • distributed data transfer (DDT)


Device Integration Technology

We offer you multiple technologies for description and integration of your field devices and other automation components. From basic integration via GSD/GSDML to all common device description technologies such as EDD, FDI or DTM, all options can be downloaded from our website.

The General Station Description (GSD) provides a framework to integrate Profibus devices into higher-level process control systems such as SIMATIC PCS 7. The description file defines basic parameters for device operation, as well as information to set up cyclic data exchange between the control system and field device. Siemens Process Instrumentation constantly pushes the limits of GSD to make basic integration of Profibus devices as convenient as possible.

An EDD or Electronic Device Description is a detailed text-based description of all configurable parameters of a field device. The device can be accessed by integration of the EDD into an appropriate EDD operating tool such as Process Device Manager (PDM). Thus, EDD allows complete parameter assignment without direct contact with the field device. Since the technology basis is independent of the operating system, the EDD offers outstanding flexibility in terms of system compatibility.

The FDI technology (Field Device Integration) was developed to centrally push ahead the standardization of FDT® and EDD. As a technology leader, Siemens AG actively drives the expansion of FDI and offers FDI packages for all new devices as part of device integration. FDI packages may be used in all host systems supporting the technology, e. g. Process Device Manager (PDM), or via interface technology of third-party suppliers.

FDT or Field Device Tool defines the data exchange between an FDT frame application and software components for field devices. Device descriptions are integrated as DTM (Device Type Manger) into the frame application (for example PactWare). As a programmed application, they offer a consistent user interface independent of the used frame application. For complete integration of field devices in FDT frame applications Siemens offers the application SITRANS DTM. Once installed, it allows integration and complete parameter assignment of device-specific DTMs for SITRANS and SIPART field devices in FDT frame applications.
