Modbus Communication Protocol History Initially, factories controlled systems through what was known as large microprocessor systems in “Distributed Control Systems” or “DCS”. A central control system managed the entire setup (in the control room). All sensors and actuators were connected to the control system via point-to-point wiring. Alternatively, they could be added in a network … Read more
Consider a DC power supply with an output socket interface that has three pins: positive, negative, and ground. Accordingly, the load’s plug should also have three pins corresponding to the power side to correctly obtain power supply. Note that there are three essential conditions that must be met: The first is that the shape, size, … Read more
