Hello , My suggestion would be reading the following link: Where and when do you need peripheral addressing? Best regards Hamid Hosseini |

Hello , If you read the FAQ,It compared both addressing.Contrarry to direct access to peripheral I/O, you can access them via process image.Process image is updated by operating system of CPU when execution of codes finished in a cycle or updated through program by means of special system function(as mentioned in the link).You have option of Scaling and Unscaling values to have meaningful access to analog signals from modules.See the attachment for more information. Converted analog inputs can be used as inputs of PID controllers or inputs for alarm and trip generation.They can also be merely used as indicators.Command to analog outputs (control valves and...) are sent via Unscaling block to analong module.
