Die Optical-Link-Module Profibus OLM hat Siemens Automation and Drives (A&D) in neuer Version 4.0 wesentlich überarbeitet und mit zusätzlichen Funktionen ausgestattet. Neu ist die verbesserte EMV-Festigkeit, die unter anderem durch das neue Edelstahlgehäuse erzielt wird, die LED-Signalisierung für LWL-Streckenqualität mit Kanalüberwachung sowie weitere Zulassungen wie Atex ExZone 2 und UL-HazLoc. Die Werte der Streckenqualität lassen sich nun auch per Messklemme zur Analogeingangsbaugruppe einer Steuerung übertragen und dort auswerten. Die neuen OLM gibt es in fünf Varianten: für alle gängigen LWL und einen erweiterten Temperaturbereich bis minus 25 Grad Celsius. Mit den Profibus OLM lassen sich optische Profibus-Netze in Linien-, Stern- und redundanter Ringstruktur aufbauen. Die Übertragungsrate einer bis maximal 15 Kilometer langen LWL-Strecke ist unabhängig von der Entfernung und beträgt bis zu 12 Megabaud/Sekunde.
