MC-Basic:IDNVALUEARRAYDOUBLE

This function works only for IDNs containing more than one Double Type value in array method .

It fills the preliminary declared Double Type Array by IDN data, and returns the number of IDN values introduced into the array.

Short form

IVALAD

Syntax

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

Availability

Since Version 4.7.12 for SERCOS III

Type

<returned value>: Long (the number of IDN values introduced into the array)

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
• The Double Type Array should be declared preliminary, and its size should be enough to contain the IDN data
• Not supported in EtherCAT system

Examples

? IDNVALUEARRAYDOUBLE (<drive>, <idn>, <element>, <double_type_array_name>)

? IDNVALUEARRAYDOUBLE (<drive>, <idn>, <element>, <double_type_array_name>, <ring>)

? IDNVALUEARRYDOUBLE (<drive>, <idn>, <element>, <double_type_array_name>, , <connection>) --> Translator note: Ring number is zero

? IDNVALUEARRAYDOUBLE (<drive>, <idn>, <element>, <double_type_array_name>, <ring>, <connection>)

-->common shared DoubleArr[1] as double

-->? IDNVALUEARRAY DOUBLE (Ax1.dadd, <IDN number>, 7, DoubleArr)
