SUB
Subtract inputs
Libraries:
Description
The SUB block implements the SUB
ladder logic
instruction. When the rung conditions are true, the block subtracts source B
(srcB
) from source A (srcA
) and outputs the result to
the destination (dest
).
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.
srcA — First input signal
scalar
The first input signal to the subtraction operation.
Data Types: int8
| int16
| int32
| single
srcB — Second input signal
scalar
The second input signal to the subtraction operation.
Data Types: int8
| int16
| int32
| single
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.
dest — Output signal
scalar
Output signal resulting from the subtraction operation.
Data Types: int8
| int16
| int32
| single
