MC-Basic:IDNVALUEARRAY

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

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

Short form

IVALA

Syntax

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

Availability

from Since Version 4.7.12 for SERCOS III

Type

<returned value>: Long (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 Long Type Array should be declared preliminary, its size should be enough to contain the IDN data.
• Not supported in EtherCAT system

Examples

? IDNVALUEARRAY (<drive>, <idn>, <element>, <long_type_array_name>)

? IDNVALUEARRAY (<drive>, <idn>, <element>, <long_type_array_name>, <ring>)

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

? IDNVALUEARRAY (<drive>, <idn>, <element>, <long_type_array_name>, <ring>, <connection>)

Example For Bosch Rexroth drive :

-->?istr(Ax1.dadd,0x8000+1120,7)

1 3 6 5

-->common shared VelFilterType[10] as long

-->? IDNVALUEARRAY (Ax1.dadd, 0x8000+1120, 7, VelFilterType)

4

-->?VelFilterType[1]

1

-->?VelFilterType[2]

3

-->?VelFilterType[3]

6

-->?VelFilterType[4]
