Abstract
An output adjustment device of an analog output module may include: a microprocessor unit (MPU) performing an arithmetic operation on a digital signal, an analog output module including an analog signal output unit receiving a signal output from the MPU to output an analog signal, and an output signal adjustment unit outputting a control signal for controlling a magnitude or amplitude of the output analog signal to the MPU.
Claims6
An output adjustment device of an analog output module for use in a programmable logic controller, configured to output an analog signal to an external side, the device comprising:
- a microprocessor unit (MPU) configured to perform an arithmetic operation on a digital signal;
- an analog output module including an analog signal output unit configured to receive a signal output from the MPU to output an analog signal;
- and
- an output signal adjustment unit configured to regulate a magnitude or amplitude of the output analog signal to output a control signal for a trial run of the output analog signal to the MPU,
- wherein the MPU includes an analog-to-digital (AD) converter configured to convert the control signal output from the output signal adjustment unit into a digital signal.
