8.7 IO-Link sensors
IO-Link is a standardized I/O technology (IEC 61131-9) for communicating with sensors and actuators.
An IO-Link system essentially consists of the following components:
•
IO-Link Master (IO-Link multiprotocol module)
•
IO-Link devices
These are field devices such as "intelligent" sensors, RFID readers, valves, I/O modules.
Intelligent in this context means that a device has a serial number or certain parameter data (such as
switching delay, limits or characteristics), which are readable or writable via the IO-Link protocol.
•
Unshielded 3- or 5-conductor standard cables
•
IO-Link configuration tool for project engineering and parameterizing the IO-Link system

The IO-Link sensors on the magazine shaft of the Stacking
magazine module can be used in combination with the light
barrier to indicate the fill level in the magazine:
•
Optical distance sensor: exact value 0-7 (analog)
•
Ultrasonic sensor: exact value 0-7 (analog)
•
Capacitive sensor: fill level limit
half full (1 - 3), full (x>3)
•
Light barrier in the magazine: empty (x=0)
