OTU is one of the building blocks of a ladder diagram. The
OTU block implements the
OTU ladder logic instruction.
When the rung condition is true, the block clears the operand tag (data bit) to false. When
the rung condition is changed to false, the block does not change the status of the data bit.
It is generally used after the OTL block to unlatch the state and disable the rung.

Specify the data bits to be modified. Data bits are specified in the format of
tags. In Ladder Diagrams, tags (variables) are used to represent
inputs, outputs, and internal memory with attributes such as
Initial Value, and
