420 Write array element 32Bit
Description
The block write accesses individual elements of a parameter array. The array parameter to be
written is connected to the input
ParAdr . The input Index specifies which element is to be written.
Value contains the value to be written. ArrSize contains the size of the array parameter.
Write access only takes place when: 0
≤ Index < ArrSize .
NOTE
It is essential to specify the correct size of the array on ArrSize . Otherwise not only the elements of
the connected array parameter may be write accessed but also other random areas of memory.
This may cause undefined reactions in the inverter. For this reason, we strongly recommend the
connection of administration block 8000009 to the input
ArrSize . This block automatically
determines the size of an array.
Inputs
No. Name Datatype Scaling Description
1 ParAdr I32 – Address of the array parameter whose elements are to be written
2 Index I16 – Index of the element which is to be written
3 Value I32 – The value which is to be written to the selected element
4 ArrSize I16 –
Size of the array connected to ParAdr (number of elements).
Specifying a size which is too large may cause random values to be
overwritten in memory, thus causing undefined reactions in the
inverter.
5 WrEnable B –
0: No value is written.
1: Value is written (when
Index is within the permissible limits).
