The FLL block implements the
FLL instruction. When the
rung conditions are true, the block fills a block of memory with the provided source value.
The Source remains unchanged.
Source elements should be scalar numeric data types.
Destination elements should be scalar numeric data types.
Source and destination elements should be of the same data type.
Source initial element index and destination element initial index start from zero.
EnableIn— Enable Input
Controls the execution of the block. EnableIn reflects the rung state preceding the block. If the rung state preceding the block is false, EnableIn is false, the block does not execute and the outputs are not updated.
It gives the value stored at source. This data is copied into destination.
length— Length of elements
Number of destination elements to fill.
EnableOut— Enable Output
By default, EnableOut follows the state of EnableIn. If the EnableIn input to the block is false, the logic implemented by the block is not executed and EnableOut signal is set to false.
Destination Array Name— Destination
The data copied from source is filled to the destination. The destination is
specified in the format of
tags. In Ladder Diagrams, tags (variables)
are used for representing all inputs, outputs, and internal memory with attributes such
Initial Value, and
size. To change the attributes of the
Name, open the Program Variables table within the
Ladder Diagram Program block.
|Type: character vector|
|Value: character vector|
Destination Initial Element Index— Destination Start Index
Destination Start Index is used only when the source is an array. It specifies the
start index of destination where the data is copied. If the source and destination data
is not stored in an array, then the value of
Destination Initial Element
Index is 1.
