Description

The SUB block implements the SUB ladder 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).

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.

The first input signal to the subtraction operation.

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.

Output signal resulting from the subtraction operation.
