This command writes the data from the preliminary declared Long Type Array to a specified element of an IDN to a specified drive. The number of elements to write is limited by <size> parameter. This function works only for IDNs containing more than one Long Type value in array method .
<element> is optional. In general, only element 7 is used (default).
Short form
WIVALA
Syntax
WRITEIDNVALUEARRAY Drive=<drive address> IDN=<IDN number> Value=<long_type_array_name> Size=<array elements number> {Element=<IDN element number>} {Ring=<ring number>} {Connection=<connection number>}
Availability
Since Version 4.7.12 for SERCOS III
Type
<drive>: Long
<IDN number>: Long
<value>: Long Type Array name
<size>: Long
<IDN element>: Long
<ring>: Long
<connection>:Long
Range
<drive>: 1 to 254
<IDN number>: 1 to 65535
<IDN element>: 1 to 7
<size>: 1 to maximal array element number
<ring>:1
<connection>:0 to 2 for normal systems (0 = chose automatically, 1 = first AT connection, 2 = first MDT connection)
Default
<element>: 7
Scope
Configuration, Task or Terminal
Limitations
- Write only
- Executed only in SERCOS communication phases 2, 3 and 4
- The IDN must be defined
- The Long type array must be declared preliminary
- <size> parameter must not be more than maximal number of IDN array elements
- Not supported in EtherCAT system
Examples
Example For Bosch Rexroth drive : -->common shared VelFilterType[10] as long -->WriteIdnValueArray Drive=ax1.dadd Idn=0x8000+1122 Value=VelFilterType size=4
