Function introduction AllenBradley SLC500 is a small frame programmable logic controller. It also includes discrete, analog, special I/O modules and related peripherals. The SLC500 controller has strong processing capabilities, and its communication network, functional modules and storage capacity can be flexibly selected and configured. RSLogix500 ladder diagram programming software provides a convenient editing and development environment. Users can click and choose to configure I≤O modules through the mouse.

The PLC is small in size, light in weight and easy to install. The PLC input and output system can intuitively reflect the changing status of field signals, and can intuitively reflect the operating status of the control system in various ways, such as internal working status, communication status, I/O point status, abnormal status, and power supply status. There are some compelling explanations, which are very beneficial for the operation and maintenance personnel to monitor the system. 1746-A10 Function Introduction The input signal types supplied to the programmable controller can be switch, analog and digital. Generally speaking, the input unit is composed of two parts: one part is the interface circuit connected with the controlled device, and the other part is the input image register.

The input unit receives various control signals from the user equipment, such as limit switches, operation buttons, selection switches, jump switches and other sensors. Through the interface circuit, these signals are converted into signals that the central processing unit can recognize and process, and coexist with the input image register. When running, the cpu reads the input information from the input image register and processes it, and stores the processing result in the output image register.

In order to prevent various interference signals and high-voltage signals from entering the PLC, affecting its reliability or causing equipment damage, the field input interface circuit generally adopts photoelectric coupling circuit isolation. The key component of the photoelectric coupling circuit is the photocoupler, which is usually composed of light-emitting diodes and phototransistors. 1746-A10 function introduction Usually the PLC input type can be DC (DC24V), AC and AC and DC. The power supply of the input circuit is provided externally. Some can also be provided internally by the PLC. For DC input, according to the form of the field input interface circuit, it is divided into two types: source input and sink input. The vast majority of European and American PLCs use leaky input, while the vast majority of Asian PLCs use source input.

The PLC is connected to the control object through the input/output terminal. PLC input and output terminals usually have three organizational forms, namely, sink type, group type and separate type. Most of the PLC's input terminals use the sink type, and some PLCs use the grouping type to increase the flexibility of use.

The temperature, pressure, and flow are collected, and the heating flow is controlled according to the collected data to achieve the purpose of energy saving. According to the outdoor climate change, by adjusting the opening of the electric valve of the original pipe network, the temperature return of the secondary pipe network can be controlled in time. By scheduling a given control curve, the operating parameters of each heat exchange station are within a given range. Colleagues, the central control room remotely controls the dispatched electric valves and adjusts operating parameters according to needs. The gprs dtu system configuration can realize temperature control and frequency conversion of filling remote pumps. The upper computer chooses to configure the king configuration software, which is combined with the database, stores and analyzes the data, and can cooperate with the optimization software for priority control.
