Process scale:How many input/output(I/O)points are required?Small systems(<300 I/O points)may have less budget,so a PLC system is more suitable.It is not easy to apply the DCS system to smaller projects.On the contrary,it can play its function better in large factory applications.Due to having a global database,the DCS system is easier to manage and upgrade,and any changes are global.

过程规模：需要多少输入/输出（I/O）点？小系统（＜300个I/O点）可能预算较少，因此用PLC系统更适合。想要将DCS系统应用到较小的项目上，其实并不容易，相反，它在大工厂应用中更能发挥其功能。由于拥有全局数据库，DCS系统更易于管理和升级，任何变更都是全局性的。
