14.4 IO-Link master / communication / conguration
IO-Link master
IO-LinkmastersareusedastheinterfacebetweenthecontrolheadsType8681(IO-Link)andthehigher-
levelcontroller.AllcommonlyusedIO-Linkmastersinaccordancewiththespecication(seechapter
“14.3”)canbeused.
The“addressing”oftheIO-LinkdevicesisdenedbytheconnectionorportontheIO-Linkmaster–Thismust
be noted when replacing the devices or master.
Communication / conguration / parametrisation
Afterthenetworkhasbeensetup(seeforexample“14.1Networkprinciple/interfaces”)andthecorrect
softwarehasbeeninstalledintheIO-Linkdevices(IODDtakingintoconsiderationtheportclass)thenetwork
isconguredusingthehigher-levelcontroller.
As described in chapter “14.1”, an IO-Link control head can also be connected in parallel to the IO-Link port
withtheBürkertCommunicator(Type8920)viatheserviceinterface(Micro-USB)ontheelectronicmodule
(see“Fig.36”onpage82).
To ensure clear communication, IO-Link devices should not be parametrised simultaneously by the higher-
levelcontroller(PLC)viatheIO-LinkmasterandwiththeBürkertCommunicator(viatheserviceinterface).
