This function is used to read the value of a specified element of an IDN from a specified drive. It should be used when reading an IDN that takes numeric values.

Use the IDNSTATE query to read the execution state of a SERCOS procedure executing on the drive.

Short form

Ival

Syntax

IdnValue (<drive address>, <IDN>, <element>, {<ring>}, {<connection>})

Availability

All versions {<ring>}, {<connection>}) options - since Version 4.7.12 for SERCOS III

Type

<returned value>: Long

Range

<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

Configuration, Task or Terminal

Limitations

  • Read only
  • Executed only in SERCOS communication phases 2, 3 and 4.
  • The IDN must be defined
  • Not supported in EtherCAT system

Examples

?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

?IDNVALUE (<drive>, <idn>, <element>, <ring>, <connection>)
