PLC是为工业自动化设计的通用控制器,不同档次PLC的响应速度一般都能满足其应用范围内的需要。

如果要跨范围使用PLC,或者某些功能或信号有特殊的速度要求时,则应该慎重考虑PLC的响应速度,可选用具有高速I/O处理功能的PLC,或选用具有快速响应模块和中断输入模块的PLC等。

主要考虑到以下三方面问题:

1)机型统一,其模块可互为备用,便于备品备件的采购和管理。

2)机型统一,其功能和使用方法类似,有利于技术力量的培训和技术水平的提高。

3)机型统一,其外部设备通用,资源可共享,易于联网通信,配上位计算机后易于形成一个多级分布式控制系统。

PLC is a general controller designed for industrial automation, and the response speed of different grades of PLC can generally meet the needs of its application range.

If you want to use a PLC across a range, or some functions or signals have special speed requirements, you should carefully consider the response speed of the PLC, you can choose a PLC with high-speed I/O processing function, or choose a PLC with a fast response module and interrupt input module.

Mainly consider the following three aspects:

1) The model is unified, and its modules can be mutually standby, which is convenient for the procurement and management of spare parts.

2) The model is unified, and its function and use method are similar, which is conducive to the training of technical forces and the improvement of technical level.

3) The model is unified, its external equipment is common, resources can be shared, easy to network communication, and it is easy to form a multi-level distributed control system with the upper computer.
