Communication is an inherent part of computers and a range of protocols and methodologies ... Some of the original serial interfaces like RS-232 and RS-485 are still widely used.

This communication is done by reading and writing control and data registers. The core implements the RS-232 protocol timing and provides ability to adjust baud rate, parity, stop, and data bits.

Modbus RTU is a widely used communication protocol in industrial automation, where a master device (PLC or SCADA) communicates with slave devices (sensors or actuators) using a compact binary format.

4-20 mA is a robust, reliable communication protocol that has been used widely in industrial settings for many years. Analog Devices’ 4-20 mA portfolio for industrial systems offers a high level of ...
