What instruction is utilized to latch an output?

The instruction used to latch an output is the OTL instruction. This instruction stands for "Output Latch" and it functions by setting a specific output bit to a high state, or "on," and retains that state even when the enabling condition is removed. When the OTL instruction is executed in a programmable controller, it effectively latches the output. This means that once the output is turned on, it will stay in the on state until it is explicitly reset by an instruction such as an OTU (Output Unlatch). This behavior is particularly useful in automation applications where a process needs to maintain a certain state regardless of ongoing conditions. In summary, the OTL instruction specifically latches an output, ensuring it remains activated as needed, which is essential for maintaining control in various operational scenarios.
