3.3.3 Process Data Input and Output
The peripheral functions comprise the process signal input and output.
• Acquisition and preprocessing of the process data from the process image of the
I/O Modules
• Periodical transfer of the process information to the open-/closed-loop control function
therein included are
─ Processed input signals as not change-monitored conditioned values
─ Processed input signals as change-monitored conditioned values
─ For processing, operations-relevant error information of the processed input signals
(for instance "measured value faulty")
• Periodical reception of the process information from the open-/closed-loop control function
therein included are
─ Derived information items
─ Processing results
─ Operations-relevant error information (for instance “command output fault”)
• Postprocessing and forwarding of the process data for the output via I/O Modules
