【Example】

(Embodiment 1) An embodiment of the present invention will be described with reference to FIGS. In the programmable controller of the present embodiment, as shown in FIG. 1 or 2, a voice synthesis output device 2 is built in a CPU unit A equipped with a CPU 1 that performs the central function of the programmable controller.

As shown in FIG. 1, the voice synthesizing output device 2 has a storage unit 21 for storing a plurality of messages as voice data, and a message for performing a selection process of appropriately reading the messages from the storage unit 21 according to an instruction from the CPU 1. The selection processing unit 22, the voice conversion unit 23 that converts the selected message into voice, and the voice output terminal 24 that outputs the voice converted to the hearing device C such as earphones and headphones. The message stored in the storage unit 21 includes the error content itself, the cause of the error, and the recovery method. Further, as the hearing device C, it is preferable to use a device such as an earphone or a headphone that hardly causes a situation where it is difficult to hear a message due to ambient noise. It should be noted that the hearing device C such as this kind of earphone does not have a problem that the message interferes with the work of the people around it.

In the programmable controller of this embodiment, when the CPU 1 of the CPU unit A receives an error signal from a unit that constitutes another programmable controller such as an A / D conversion unit, a D / A conversion unit, or a link unit. Then, the error content is discriminated, and a command for causing the message selection processing unit 22 to read a message according to the error content is given. here,
In the case of the present embodiment, the CPU 1 converts an error signal received from another unit into an error number corresponding to the message and gives the error number to the message selection processing section 22. The error or trouble includes an error or trouble of the programmable controller itself and an error or trouble of a device controlled by the programmable controller.

Upon receipt of this error number, the message selection processing unit 22 selects from the storage unit 21 the data corresponding to the message corresponding to the error number, reads it, and outputs the data to the voice conversion unit 23. . The voice conversion unit 23 performs voice synthesis based on the data. Therefore, by connecting an earphone or the like to the audio output terminal 24, the contents of the error, the cause of the error, and the recovery method can be heard by voice. Note that FIG. 3 shows a flowchart summarizing the above operations.

In this way, the error content can be grasped and the error content can be heard by voice even without using a simple handy programmer or programming support tool. Therefore, a manual or the like is required. There is an advantage of not doing it. Moreover, if it is voice,
There is also an advantage that there is no problem that the display is difficult to see in a dark place as in the case of a liquid crystal display.

(Embodiment 2) Still another embodiment of the present invention will be described with reference to FIGS. In this embodiment, basically, the error contents are confirmed by using a program input device such as a simple handy programmer or a programming support tool as in the conventional case. However, in the case of the present embodiment, even a person who is not familiar with how to use the program input device such as the above-mentioned simple handy programmer or programming support tool can confirm the error content. That is, in this embodiment, the programmable controller can assist in confirming the error content with the program input device.

Also in the case of the present embodiment, as shown in FIG. 4 or 5, the CPU unit A is provided with a support function for error confirmation work, and the CPU unit A is provided with a voice indicating how to use the program input device, that is, the input procedure. A voice synthesis output device 2 for outputting is provided. The basic configuration of the voice synthesis output device 2 is the same as that of the first embodiment. The content stored in the storage unit 21 is a message related to the input procedure, and a message instructing a coping method when the input procedure is incorrect is stored.

In this embodiment, when the program input device B is used to confirm the error content, when assistance is required, the program input device B is connected to the CPU unit A and is specified from the program input device B. Perform the input operation of. By this input operation, the CPU 1 gives the message selection processing section 22 an instruction to select a message corresponding to the input procedure to be performed first by the program input device B. In this case, the CPU 1 gives the procedure number to the message selection processing device 22. As a result, the person who is operating the program input device B is given by voice the procedure to be performed first.

When an input operation is performed for the voice-output procedure, the next procedure is voice-outputted to sequentially instruct the input procedure. By doing so, even a person who is not familiar with how to use the program input device can confirm the error content. By the way, an input operation different from the procedure instructed by the programmable controller may be performed. Therefore, if there is an error in the input procedure correspondingly, the fact that there is an error in the input operation is notified by voice. In this case, C
The message selection processing unit 22 selects a message corresponding to the input procedure error from the storage unit 21 according to the error number instruction from the PU 1, and notifies the input procedure error by voice.
By doing so, even if the program input device is used, the error content can be confirmed relatively easily.

(Embodiment 3) Still another embodiment will be described with reference to FIGS. This embodiment is basically the same as the first embodiment, and when the CPU unit 1 receives an error signal from another unit, the contents of the error can be confirmed by voice. The feature of this embodiment is that a message such as an error content can be output as voice in a plurality of languages, such as Japanese, English, and French.

The operation of this embodiment is basically the same as the case of performing only in Japanese. Here, the language to be output as voice is selected by, for example, using the program input device B for the CPU.
It suffices if it can be performed for the CPU 1 of the unit A. In this case, the CPU 1 sends the error number together with the language identification number to the message selection processing unit 22, and the message selection processing unit 22 reads the message corresponding to the error number from the language file in the storage unit 21 designated by the language identification number. By enabling voice output in a plurality of languages in this way, the content of an error can be confirmed without any trouble even when a person using a plurality of languages works together.

By the way, in the above-mentioned case, the storage unit 21 for storing messages in a plurality of languages is used, but if the chips corresponding to various languages can be exchanged, it can be applied to use in each country. Is also possible. (Embodiment 4) Still another embodiment of the present embodiment will be described with reference to FIGS. In this embodiment, the programmable controller can support the operation of the program input device B of the second embodiment so that the instruction of the input procedure and the error instruction of the input procedure are given in a plurality of languages. It is the one.

Correspondingly, it is provided with a storage unit for storing data of a message to be output as voice, and a voice conversion output unit for appropriately reading message data according to the result of determination of error or trouble content of the processing unit and converting and outputting the voice. Therefore, the programmable controller itself can inform the checker of the content of the error or trouble, and the check operation can be performed without the need for the program input device. Further, since the contents of an error or trouble are communicated to the confirmer by voice, it is not necessary to collate with a manual or the like as in the case of displaying, and the confirming work can be easily performed.

According to a second aspect of the present invention, a processing section for performing processing for instructing the input procedure based on a command for instructing the input procedure given from the program input device, and an input procedure or an error in the input procedure is dealt with. An input procedure of the program input device is provided because it includes a storage unit that stores data of a message to be output as voice, and a voice conversion output unit that sequentially reads message data according to an instruction from the processing unit, performs voice conversion, and outputs the voice data. Can be instructed by the programmable controller, and even a person who does not know how to use the program input device can check the content of the error or trouble.

According to the third aspect of the present invention, since the storage unit can be freely exchanged with the one for storing message data in different languages, the storage unit can be replaced even when used in different countries. . According to the fourth aspect of the invention, the storage unit is provided with a storage unit for storing message data in a plurality of languages, and a designating unit for designating the language of the message to be output by voice is provided.
According to the instruction of the designation means, the processing unit gives the voice conversion output unit an instruction to output the message in the designated language to the voice conversion output unit. Therefore, by selecting the language of the message, the language used can be changed. It is possible to handle even mixed sites.
