Abstract

Die Erfindung betrifft die Standardisierung von Winkelmesseinrichtungen. Eine Abtasteinrichtung (20) soll derart ausgestaltet werden, dass sie zur Abtastung eines ersten geschlossenen Codes (C1) und eines zweiten geschlossenen Codes (C2) geeignet ist. Der zweite Code (C2) ist dabei ein zusammengefügter Ausschnitt (V) aufeinanderfolgender Codeelemente (A3 bis A13) des ersten Codes (C1). Hierzu weist die Winkelmesseinrichtung eine Abtasteinrichtung (20) auf, deren Decodiereinrichtung (30) in Abhängigkeit einer Kennung (ID), welche die zu dekodierenden Codes (C1, C2) voneinander unterscheidbar definiert, in einer ersten oder in einer zweiten Betriebsweise betreibbar ist. In der ersten Betriebsweise wird der erste Code (C1) durch eine Decodiertabelle (T2) mit einem ersten und einem zweiten Wertevorrat decodiert. In der zweiten Betriebsweise wird der mit dem ersten Code (C1) übereinstimmende Teil (V) des zweiten Codes (C2) ebenfalls durch den ersten Wertevorrat der Decodiertabelle (T2) decodiert und die durch das Zusammenfügen des vom ersten Code (C1) übernommenen Ausschnitts (V) am Stoß (ST2) neu gebildete Abfolge von Codeelementen des zweiten Codes (C2) wird durch eine zusätzliche kleine Decodiertabelle (T5) mit einem dritten Wertevorrat decodiert.
