COP
Copy File
- Library:
Description
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.
Ports
Input
EnableIn — Enable Input
off (default) | on
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.
src — Source
scalar | vector | matrix
It gives the value stored at source. This data is copied into destination.
Data Types: int8 | int16 | int32 | int64 | single | String | Structure
length — Length of elements
scalar
It gives the number or source elements to copy.
Data Types: int8 | int16 | int32
Output
EnableOut — Enable Output
off (default) | on
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.
Parameters
Source Initial Element Index — Source Start Index
1 (default) | scalar
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.
Programmatic Use
Block Parameter:
PLCSRCArrayIndex |
| Type: scalar |
| Value: scalar |
Default: 1 |
Data Types: int8 | int16 | int32 | single
Destination Array Name — Destination
A (default) | boolean
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
Data Type, Initial Value, and
size. To change the attributes of the Destination Array
Name, open the Program Variables table within the
Ladder Diagram Program block.
Programmatic Use
Block Parameter:
PLCOperandTag |
| Type: character vector |
| Value: character vector |
Default: 'A' |
Destination Initial Element Index — Destination Start Index
scalar
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.
