2.3 IO-Link interface
Example plant with IO-Link
The figure below shows an example of plant architecture with IO-Link.
Figure 2-1 Plant architecture with IO-Link
The IO-Link master establishes the connection between the IO-Link devices and the
automation system. If the IO-Link master is a component of the I/O system, it is installed
either in the control cabinet or directly in the field as remote I/O in degree of protection
IP65/67. The IO-Link master communicates by means of various fieldbuses or product-specific
backplane buses. An IO-Link master can have multiple IO-Link ports (channels). An IO-Link
device can be connected (point-to-point communication) to each port.
Engineering
The IO-Link system is engineered parallel to the overall automation system and can be
embedded in it and intermeshed with it.

IO-Link interface
Introduction
The IO-Link is a serial, bidirectional point-to-point connection for signal transmission and
power distribution under any network, fieldbus or backplane bus.
