IO-Controller (EN)

IO-Controller

The IO-Controller is a central control device in Profinet networks that coordinates communication with IO-Devices and other network components. It manages the entire topology of connected devices and controls data exchange between the control level and peripheral devices. The controller must know the device parameters and configuration to ensure deterministic and reliable communication in the automation environment.
