Description

The RS-232 standard was first introduced in 1962 by the Radio Sector of the EIA. The original DTEs (data terminal equipment) were electromechanical teletypewriters, and the original DCEs (data circuit-terminating equipment) were usually modems. For many years, an RS-232-compatible port was a standard feature for serial communications, such as modem connections, on many computers. The RS-232 standard is still used to connect industrial equipment (such as PLCs), console ports and special purpose equipment.

The IEEE RS-232 standard defines electrical, signal timing, and size connectors. Use of a common ground, limits RS-232 to applications with relatively short cables. RS-232 connection consisting only of transmit data, receive data, and ground. RS-232 protocol uses bipolar signal. Valid signals are ±3 to +15 volts, the ±3V range is not a valid RS-232 level. Data signals between -3V and -15V represents a logic 1. The logic 0 is represented by a voltage of between +3V and +15V.

Modbus allows communication between many devices connected to the same network, for example a system that measures temperature and humidity and communicates the results to a computer

Many of the data types are named from its use in driving relays: a single-bit physical output is called a coil, and a single-bit physical input is called a discrete input or a contact.
