4.6 Input and output modules
The I/O modules form the interface between the controller and the process. The controller
detects the current process state via the connected sensors and actuators, and triggers the
corresponding reactions.
Digital and analog modules provide the inputs/outputs that are re-
quired for the respective task.
The input/output modules are divided into function classes.
Function classes of input/output modules
The table below shows selected properties and technical specifications of different function
classes of input/output modules.
Function class
High Speed (HS)
Special modules for extremely fast
applications
Shortest input delays
Shortest conversion times
Isochronous mode
High Feature (HF)
Flexible use
Even for complex applications
Parameters for each channel
Diagnostics for each channel
Add-on functions

• Highest accuracy (< 0.1%)
• High common mode voltage (e. g.
60 V DC / 30 V AC), with single-
channel electrical isolation if re-
quired
Standard (ST)
Medium price range
