摘要
随着工业技术的不断发展,PLC技术应用也越来越广泛,PLC技术给工业控制带来了很大的便捷,提供了全新的工业控制方式,提高了工业控制的精度,但同时由于PLC系统是精密的电子元器件组合而成的控制系统,包括数字量的输入输出,也有模拟量的逻辑运算,现在的工业环境复杂,这些对系统的稳定性以及抗干扰性提出了很高的要求,因此要从硬件上以及软件上做好各项抗干扰措施,以提高PLC的稳定性。
With the continuous development of industrial technology, PLC technology application is becoming more and more widely, the PLC technology brings a lot of convenient to the industrial control, provides a new way of industrial control, improves the accuracy of the industrial control, but the PLC system is a combination of sophisticated electronic components control system at the same time, including digital quantity input/output, also has analog logic operation, now the industrial environment is complex, therefore the high request for system stability and anti-interference measures is proposed. So, we must make various anti-interference measures from the hardware and software.
