Wie funktioniert eigentlich die neue Kommunikationsschnittstelle IO-Link des WIKA Druckschalters PSD-30? IO-Link ist eine Punk-zu-Punkt-Verbindung (also kein neuer Feldbus) zwischen dem Sensor\/Aktor und einem Feldbusmaster wie z. B. einer SPS. \u00dcber die in der Feldebene typische und standardisierte 3-Leiter Anschlussleitung erfolgt die Versorgung des Feldger\u00e4tes (Pin 1 und Pin 3) und die Signal\u00fcbertragung (Pin 4).<\/strong><\/p>\n

Die Signal\u00fcbertragung erfolgt zun\u00e4chst konventionell, das hei\u00dft ohne IO-Link im so genannten SIO-Mode (Standard IO-Mode). Erst wenn \u00fcber den IO-Link Master mittels eines definierten Befehls ein so genannter \u201eWake Up\u201c durchgef\u00fchrt wird, wird die digitale IO-Link Kommunikation gestartet. Dann werden \u00fcber ein serielles Protokoll standardisierte Datenpakete bidirektional ausgetauscht. Konfigurationsparameter k\u00f6nnen jetzt zentral von der Steuerung in den Sensor und Messwerte sowie Diagnosedaten aus dem Sensor in die Steuerung \u00fcbertragen werden.<\/p>\n

Die IO-Link Funktionalit\u00e4t des Sensors wird in einer Ger\u00e4tebeschreibungsdatei (IODD \u2013 IO-Link Device Description, xml-Datei) abgebildet und muss im verwendeten IO-Link Interpreter Tool gespeichert werden.<\/p>\n

Technische Informationen zu IO-Link:
\n<\/strong>Datenrate: 4,8 \/ 38,4 \/ 230,4 kBaud
\nMax. Leitungsl\u00e4nge: 20 m, ungeschirmt
\nTypische Zykluszeit: 2 ms
\nVerbindungstyp: Punkt-zu-Punkt, seriell, bidirektional, halbduplex
\nStandardsteckverbinder: M5, M8, M12<\/p>\n
