The COP block implements the
COP instruction. When the
rung conditions are true, the block is used to copy the data of the source and store it at the
destination, keeping the source unchanged.
Source and destination elements support only numerical data types.
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
It gives the number or source elements to copy.
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.
Source Initial Element Index— Source Start Index
Source Start Index is used only when the source is an array. It specifies the index
of the first element to be copied into destination. If the source is not an array, then
the value of
Source Inital Element Index is 1.
Destination Array Name— Destination
The data copied from source is stored in 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 as
Initial Value, and
size. To change the attributes of the
Name, open the Program Variables table within the
Ladder Diagram Program block.

|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.
