Search WeChatTechnical Training The function of PLC automatic sequencing is to control equipment to operate according to a pre-designed process flow. There are several methods for writing PLC automatic programs, and below we will provide a detailed explanation. PART 01First Method: Set and Reset Auxiliary Relays This method is the most primitive and basic way … Read more
With the development of computer technology, new electrical control systems based on technologies such as Programmable Logic Controllers (PLC), variable frequency drives, servo drive systems, and computer communication and configuration software have gradually replaced traditional relay control systems and are widely applied in various industries. Among them, Siemens and Mitsubishi’s PLCs, variable frequency drives, touch … Read more
Differences Between Three Types of PLC Outputs1. Relay Output:The advantage is that different common points can carry different AC and DC loads, and the voltage can also be different, with a load current of up to 2A per point; however, relay output is not suitable for high-frequency loads, which is determined by the relay’s lifespan. … Read more
