With the help of an ARM microprocessor, a HART protocol modem chip, and a great deal of real-world knowledge, the SM100-M-16 HART data collector was created. It offers great stability and dependability and is designed to meet the specifications of industrial items. To ensure real-time data transmission, the data collector is outfitted with a standard RS485 interface and gateway that can either convert data into MODBUS_RTU or MODBUS_TCP protocol to read data or transparently communicate data with intelligent instruments using HART protocol.
The HART protocol instrument enables bidirectional data transmission without interfering with the 4 to 20 mA analog signal by superimposing a modulated digital signal on a 4 to 20 mA basis using the Bell202 Frequency Shift Keying (FSK) standard. An clever converter for bidirectional modulation and demodulation of digital and analog signals is the SM100-M series HART data collector.
