Basic knowledge
IO-Link is defined as a standardized point-to-point connection between sensors/actuators and
an I/O module. An IO-Link sensor/actuator can send additional communication data (e.g. diag-
nostics signals) in addition to the binary process signals over the IO-Link interface.
Compatibility with standard I/O:
– IO-Link sensors/actuators can be connected to existing I/O modules if they are operated in
SIO mode
– Sensors/actuators that are not IO-Link-capable can be connected to a decentral IO-Link
module
– Standard sensor/actuator cables can be used
Key technical data:
– Serial point-to-point connection
– Communication as add-on to standard I/O
– Standard I/O connection technology, unshielded, 20 m cable length
– Communication using 24 V pulse modulation, standard UART protocol
The IO-Link port can be operated in various modes. Functions are available on pins 2 and 4.
Pin 2 of the IO-Link port can be configured for the following standard I/O operating
modes:
– Input as normally open contact
– Input as normally closed contact
– Output
Pin 4 of the IO-Link port can be configured for the following standard I/O operating
modes:
– Input as normally open contact
– Input as normally closed contact
– Output
– IO-Link communication
– IO-Link input as normally open contact with SIO function
– IO-Link input as normally closed contact with SIO function
In SIO mode an IO-Link device can be configured via IO-Link and afterward switched over to an
SIO mode in which the IO-Link port pin functions as a simple switch input.
Connected IO-Link and I/O modules are powered by the processor unit. For information about
