What occurs when an OTE instruction is executed in a PLC?

When an OTE (Output Energize) instruction is executed in a PLC, it specifically applies power to the associated output device. This instruction is fundamental in PLC programming as it allows the controller to manage outputs based on the logic defined in the program. When the OTE instruction is engaged, the PLC sends a signal to the output device, enabling it to operate—be it turning on a motor, lighting a bulb, or activating a relay.

This operation depends on the conditions set in preceding instructions and the current state of the inputs. If these conditions are met, the OTE instruction energizes the output, which is essential for controlling processes and machinery in an automated environment. Understanding how the OTE instruction functions is crucial for effectively using PLCs in various applications.
