1. Input Circuit Wiring The input circuit is the port through which the PLC receives signals (for analog signals, typically 0-40mA DC current or 0-10V DC voltage signals). Input wiring refers to the external input devices (any passive contacts and NPN transistors with open collector) that connect to the input circuit, closing the circuit and … Read more
PLC (Programmable Logic Controller) is the core of industrial automation, and its correct use and maintenance are key to ensuring stable, reliable, and long-lasting operation. The following are important considerations when using PLCs, covering safety, installation, programming, maintenance, and more.1. Safety Considerations (Top Priority!)1. Power Off Operations: Before wiring, disassembling modules, or connecting devices, be … Read more
Introduction INTRODUCTION In industrial automation programming, timers are one of the most commonly used components in control logic. While standard timers like TON and TOF can meet most scenarios, are there more flexible implementations for situations that require special timing accuracy or want to break free from “relying on the system’s default timer”? A user … Read more
1 Concept Data types are used to specify the size and format of data elements, as well as how to interpret the data, describing the length of the data (i.e., the number of binary bits) and its attributes. All data in user programs must be identified by data types, and only variables of the same … Read more
