SIPART PS2 with and without HART communications

234 Operating Instructions, 09/2007, A5E00074631-07

Final controlling element

Converter that converts electric signals into mechanical or other non-electric variables.

Firmware

Firmware (FW) is the software embedded in a chip in electronic devices. It is not like

software that is stored on hard disks, CD-ROMs or other mediums. These days, the firmware

is mostly stored in a flash memory or an EEPROM. Firmware is software in the hardware,

and is thus an intermediate between the software and the hardware. Firmware is normally

model-specific. This means that it does not function on other device models and is delivered

by the manufacturing company. The corresponding devices cannot function without the

firmware. The firmware mostly contains elementary functions to control the device, as well as

input and output routines.

Foundation fieldbus

Syndicate of manufacturers of measurement and control systems. The syndicate develops

the open fieldbus specifications of the FOUNDATION fieldbus.

FOUNDATION fieldbus

Fieldbus to connect sensors and final controlling elements in hazardous areas as per IEC

61158-2. The FOUNDATION fieldbus uses a common 2-wire cable for data communication

and power supply. Data communication and power supply. The FOUNDATION fieldbus uses

bus types such as High Speed Ethernet and Foundation H1.

Frequency shifting process

The frequency shifting process is a simple modulation format in which digital values 0 and 1

are represented by two different frequencies.

GSD file

The file that describes the properties of a PROFIBUS DP slave or a PROFINET IO device.

The GSD file is a database file for PROFIBUS devices. The device manufacturer provides

the corresponding GSD file containing the description of device properties. The information

in the file can be read using Engineering Tools.

HART

HART (Highway Addressable Remote Transducer) is a standardized and widely used

communication system for erecting industrial fieldbuses. This communication system

enables digital communication of multiple participants (field devices) using a common data

bus. HART implements the widely used 4/20 mA standard to transfer analog sensor signals.

Existing cables of the old system can be used directly and both systems can be operated

simultaneously. HART specifies several protocol levels in the OSI model. HART enables

transfer of process and diagnostics information and control signals between field devices

and superordinated control system. Standardized parameter sets can be used for

manufacturer-independent operation of all HART devices.
