Going Digital while using the Analog Infrastructure
Entering the world of IIoT and Industry 4.0
In PA (Process Automation) the majority of process instrumentation makes use of a 4-20 mA infrastructure. With the rapid development of computing power with a small footprint Instrument intelligence became an easy to implement and affordable solution.
Over the world there are more than 30 million field instruments installed with HART technology. Making the field device a SMART instrument that can participate in the next generation of PA. IIoT (Industrial Internet of Thing) and Industry 4.0 rely on SMART Instruments to enable a more predictive plant where Reliability and Efficiency can be increased due to the availability of diagnostic information.
"intelligent devices through digital communication"
HART - DIGITAL TRANSFORMATION FOR ANALOG INSTRUMENTS
HART is the global standard for sending and receiving digital information across the 4-20mA analog current loops that connect the vast majority of field instruments with distributed control systems. HART technology offers a reliable, long-term solution for plant operators who seek the benefits of intelligent devices with digital communication, while preserving existing investments in analog instrumentation and plant wiring. Much more than a communication protocol, with HART technology process plants have access to a wealth of digital process, maintenance, and diagnostic information. Information that is valuable throughout the plant lifecycle from design, to installation and configuration, through operation, and finally maintenance.
HART is simple, reliable, and easy to use.
HART is a bi-directional communication protocol that provides data access between intelligent field instruments and host systems. A host can be any software application from technician's hand-held device or laptop to a plant's process control, asset management, safety or other system using any control platform. Communication occurs between two HART-enabled devices, typically a smart field device and a control or monitoring system. Instrumentation grade wiring and standard termination practices assure reliable communication.
HART COMMUNICATION TOOL
The HART field communicator (KAP-03/KAP-03Ex) is a portable device used for communication and exchange of data with smart transmitters e. g. pressure, differential pressure, temperature transmitters. It features an output built as a standard current loop 4-20 mA, using FSK modulation type BEL 202 with an implemented HART communication protocol revision 5 and revision 6. The communicator is specially designed to configure smart transmitters manufactured by APLISENS.
