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.
HART communicator
Connection with a two-wire line is directly established for the parameter assignment with the
HART communicator. For the parameter assignment with a laptop or a PC, a HART modem
is connected in between.
Increment
From the Latin word incrementare, increase. Increment is the defined amount of change
when increasing a variable(s) gradually. In informatics, it is referred to as the stepwise
increase in a numeric value.→Decrement.
Initialization
Setting the most important basic parameters. Requirement for commissioning the positioner.
IP code

countries, IP stands for Ingress Protection.
Microcontroller
Microcontrollers (also µController, µC, MCU) are single-chip computer systems in which
almost all components such as master processor, program memory, working memory and
