All versions {<ring>}, {<connection>}) options - from AMCS 0.4.7.12 for SERCOS III
Type
<returned value>: Long

<drive address>: 1 to 254
<IDN>: 1 to 65536
<element>: 1 to 7
<ring>:1
<connection>:0 to 2 for normal systems (0 = chose automatically, 1 = first AT connection, 2 = first MDT connection)
Scope

?IdnValue(1, 189, 7) ‘Get drive position following error
?IDNVALUE (<drive>, <idn>, <element>)
?IDNVALUE (<drive>, <idn>, <element>, <ring>)
?IDNVALUE (<drive>, <idn>, <element>, , <connection>) --> Translator note: Ring number is zero
