Claims (1)

[Claims for Utility Model Registration] Data importing means for importing data sent to the unit onto the system bus of the programmable controller; decoding and outputting the imported data as a voice output command; command decoding means for detecting the voice content to be outputted and the presence or absence of an output start command; pronunciation command means for issuing a pronunciation command related to the detected voice content in response to the detection of the presence of the output start command; audio signal generating means for generating a corresponding audio signal in response to a command; amplifying means for amplifying the audio signal to an extent capable of driving a monitor speaker; and selectively generating the original audio signal or the amplified audio signal. 1. An audio output unit for a programmable controller, comprising: switching means for outputting audio to an output terminal;
