What is PLC?
PLC integrates computer technology, automatic control technology and communication technology, adopts user-oriented "natural language" programming for control, is suitable for industrial environment and is simple and easy to understand, easy to operate and highly reliable industrial control equipment. PLC is a general automatic control device with microprocessor as the core, developed based on relay sequence control.
Technicians will say: PLC is an advanced control technology.
Sales staff will say: PLC is money and market, they can directly sell PLC without understanding PLC technology.
The boss of the automatic control company will say: PLC is a profitable industrial control product.
In fact, PLC is time.
The emergence of PLC has shortened the production cycle of automobile production lines from the original production cycle of 6-9 months to 6-9 weeks, and the same is true of steel, petrochemical and other production, because the establishment of the automatic control system has greatly shortened the production cycle and production volume. What does the time saved mean for the business? That is profit. Wireless PLC is more time efficient.
The PLC product itself does not create any value. It needs to be carefully crafted by engineers before it can be used in production to show its strong value capability. It is the value created by PLC that can save time that makes PLC mature and widely used in various industries from FA to PA due to its stability, low cost and wider functional extensibility.
Basic functions of PLC
Logic control function, timing control function, counting control function, step control function, data processing function, loop control function, communication networking function, monitoring function, power failure memory function, fault diagnosis function.
