PLC Programming Fundamentals – OTE Instruction

The OTE, also known as Output Energize, instruction will energize a single bit of data if the input leading to it is true. It’s a fundamental instruction used in Programmable Logic Controllers (PLCs). This instruction will be found on the right side within a ladder logic structure and turn a bit to a HIGH state if the preceding instructions evaluate to true. If the same instructions evaluate to false, the OTE instruction will set the specified bit to a LOW state.
