Why Monitoring and control done?

Monitoring and control using microprocessors/computers is often done for the below reasons:

- It is safer (faster response to non-standard conditions and they do not get tired and miss key data)

- Computers work 24*7 (although humans can work in shifts there is always the danger of missing information at shift handover etc.)

- Computers are more accurate and can take more frequent readings (for example if readings need to be taken every 30 seconds, humans can make mistakes or miss readings or even find it impossible to take readings at such short time intervals)

- Data can be automatically displayed and analysed without the need to enter data manually (which in itself could introduce errors into system).
