In industrial automation, the HART (Highway Addressable Remote Transducer) protocol is a widely adopted communication standard. It cleverly superimposes digital signals onto the traditional 4-20mA analog current loop, enabling compatible transmission of both analog and digital data. Engineers often ask a common question when building HART communication loops: Why must a 250 ohm resistor be […]

The MC0312 from Microcyber is a compact, high-performance embedded core module designed to bridge legacy Modbus-RTU devices with modern Ethernet-APL (Advanced Physical Layer) networks. Compliant with the 10BASE-T1L (IEEE 802.3cg) standard, it enables seamless upgrade of existing Modbus-based field instruments (such as temperature, pressure, flow, level transmitters, and actuators) to HART-IP protocol over Ethernet-APL. This […]

The HART (Highway Addressable Remote Transducer) protocol is a widely adopted communication standard in process automation, enabling digital data transmission alongside traditional 4-20 mA analog signals. One of its key features for improving efficiency is Burst Mode, which allows field devices to periodically broadcast process data and diagnostics without constant polling from the host system. […]
