Programmable controller are a stored program controlled device, the control function is achieved through the program stored in the memory, To make changes to the control function, in large part only need to change the software instructions can beso that the hardware and software technology. Increasing its position in industrial control, occupies an extremely important position, the most important reason is that it has the following unique characteristics of high reliability, easy to learn programming versatility, the system design cycle is short, the production process change adaptable, simple installation, commissioning, maintenance workload and adapt to the industrial environment. In short, the elevator control more complex, the use of programmable controllers for elevator control a vast space. mitsubishi elevator PLC is designed specifically for industrial process control equipment, with the application of mitsubishi elevator PLC technology continues to evolve, will make its volume greatly reduced, function continuously improved process control more stable and reliable. Strong anti-jamming performance, mechanical and electrical components organically combined in one device, instrumentation,electronics and computer functions combined. Therefore, it has become a key technology in the elevator running.
