A HART communicator is a portable device, based on HART communication protocol. A HART communicator works as a secondary master in a control loop. A field communicator supports both HART and Foundation Fieldbus devices. HART communicator devices are used to check variables online and for calibration purposes. The communicator is portable, thus wireless runs in …
The WirelessHART™ standard provides a robust wireless protocol for the full range of process measurement, control, and asset management applications. It adds wireless capabilities to the HART Protocol while maintaining compatibility with existing HART devices, commands, and tools. A wirelessHART device uses nominal 2.4GHz transmission frequency using IEEE 802.15.4 standard radios because meeting these criteria allows WirelessHART …
What is HART protocol? HART (Highway Addressable Remote Transducer) Protocol is the global standard for sending and receiving digital information across analog wires between smart devices and control or monitoring system. HART is owned by independent non-profit HART communication foundation. HART is now a global standard because digital information from HART devices can simultaneously communicated with the …

RS-232 C is a standard connection between a modem and the devices, electrical specifications, data exchange method, and timing. They perform different functions at the sending and receiving ends. At the sending end, a serial digital signal is used to modulate an analog signal (using, for example, frequency modulation), which is sent out on the communication circuit; on …
Introduction The industrial automation systems is divide into several hierarchical level.Each of the stage or level has an appropriate communication level.which stage or level different requirements on the communication network.Industrial communication may be classified in different categories based on functionality-field-level networks,control level networks and information-level networks.at lowest level we use sensor and actuator buses to …
