IEC 61131-9
Point-to-point communications protocol from the fieldbus to the sensor and actuator level.
IO-Link master acts as a gateway between the IO-Link device and the higher level communication system, such as a fieldbus (Profinet, EtherNet/IP, etc.) or a device-specific backplane bus.
IO-Link device is the field device with communication capability: sensors, switching devices, valve terminals, RFID devices, indicator lights, etc.

IO-Link master
… acts as a gateway between the IO-Link device and the higher level communication
system, such as a fieldbus (Profinet, EtherNet/IP, etc.) or a device-specific backplane bus.
IO-Link device
… is the field device with communication capability: sensors, switching
devices, valve terminals, RFID devices, indicator lights, etc.
3-core unshielded standard cable – up to 20M long
… is the standard interface between IO-Link master and device
IODD and engineering tool
… are used to configure and assign parameters to the IO-Link system and devices.
an IO-Link system generally consists of the following
basic components:
9. easier handling of measurement
devices
9
traditionally
better
best
lower cost – no analogue
card
lower cost vs IE networked
device
less wiring effort
12. • Short circuit – LED for each I/O port
• Short circuit does not impair the unit
• Sensor/actuator under voltage LED for each I/O port
extensive diagnostics:
12
16. Time consuming configuration of 10 – 15 Parameter.
(e.g. upper/lower Pressure point,
Hysteresis, Time – or Pressure window)
Machine Tools have often more than
10 Pressure sensors
Error prone due to manual entry
Very bad when Sensor failure / Sensor
exchange
(especially during night shift)
parameterisation – std pressure sensor
16
Manual
configuration
18. HMI integrated in sensor for set up
means additional cost.
Expensive high-pressure hydraulic
hoses
parameterisation – std pressure sensor
18
machine tool
Additional cost for protective
housing for sensors in the machine
21. sensor installed at point of
measurement
no expensive measurement cables
- use std un-shielded 3-wire
standard cables
no protection case
no sensors with HMI but reliable
parameterisation via controller and
HMI of the machine
decentralised diagnostics for
sensors
parameterisation – pressure sensor with IO-Link

27. device configuration
27
1. controller parameter storage –
parameterisation from the PLC using the
function block
2. IO-Link master ver 1.1 parameter server
3. PC storage with USB master
4. webserver entry with IO-Link master
5. Manual configuration
29. Drag the appropriate (process data length) IOL input / output
byte from the catalogue and name & address the module
IO-Link master configuration
