A keyboard 14 on which EXE keys are arranged is an input control unit for sending coordinate information output from the touch panel 12 and codes of various keys output from the keyboard 13 to the main control unit 15. Based on the coordinate information sent from the input control unit 14, the main control unit 15 records the number of digital data output requests, the instrument number for which the digital data output request was made, the output location of the instrument, etc. in the data output information management table 16. At the same time as registering, digital data is output while checking the registration status of the data output information management table 16 based on the operation of the EXE key. Reference numeral 17 represents an input/output port, and 18 represents a group of instruments to which digital data is output collectively as external equipment.

The data output information management table 16 has an area configuration as shown in FIG. 2, for example. That is, this data output information management table 16 has a request number registration area 20 in which the number of digital data output requests is registered, n pieces (n is 1).
Instrument number registration areas 21-1, 21- for registering up to n numbers of requested instruments in order of request when there is a request for output of digital data (larger integer).
It is composed of output point registration areas 22-1, . . . 22-n for registering up to n output points of the requesting instruments when n, n digital data output requests are made.

Next, in FIG. 3, an instrument display screen representing instruments for outputting digital data is displayed on the screen of the CR7 display unit 11. In the figure, numeral 31 is a push button switch instrument, and the inside of the frame is a touch area within the push button switch/sochi instrument. In this push button switch meter 31, 32 indicates that the meter number is N, and 33 and 34 indicate that there are two output points of digital data, rONJ and rOFFJ. Then, when you touch either "ON" or rOFFJ, the number of output requests changes to "
1”. Further, 36 is a motor instrument, and the area within the frame is a touch area within the motor instrument. And 37 indicates that the instrument number is M,
Further, 38 and 39 indicate that there are two output points for digital data: "operation" and "stop". this"
"Run" or "Stop" shall also be defined as the number of output requests or "1", respectively. In addition, if the output point actually handled in the output process is a push button switch, "ON" is "
1" rOFFJ is numbered from the top, such as "2".

Next, FIG. 4 is a diagram showing the key arrangement of the keyboard 13. In other words, this keyboard 13 has numeric keys 41, E

In this device, an instrument display screen as shown in FIG. 3 is displayed on the CR7 display section 11 by operating the instrument display screen output key among the function keys 43, and processing of a digital output request is started. First, in step STI, it is determined whether or not there is a digital data output request. If there is no data output request, the program returns to the beginning, and if there is a data output request, it is output from the touch panel 12 corresponding to the instrument display screen shown in FIG. Based on the coordinate information, for example, if 32 is touched, the instrument number N is entered in the instrument number area 21-1 of the data output information management table 16, and the push button switch of this instrument number N is turned on.
J, that is, when you touch the output point, the instrument number N
The output location and the number of data output requests "1" are respectively registered (step 5T2). Note that a code representing "ON" is registered in area 22-1.

Thereafter, the process moves to step ST3, and it is determined whether or not the EXE key 42 has been pressed. Here, if the EXE key 42 is not operated, return to the beginning of the program again,
Repeat execution from step STI. If there is an output request for the "operation" of the output point 38 for the instrument number M of the motor instrument 36, add 1 to the area 20 or the output request and then "2".
”, and register M in area 21-2 and a code representing “driving” in area 22-2 (step 5T2).
.

When the EXE key 42 is operated in step ST3, it should be set to i-1 (step 5T4), area 2
According to the contents registered in 1-1 and 22-1, digital data is output to rONJ of pushbutton switch N (step 5T5), and i is incremented (step 5
T6).

After that, in step ST7, it is determined whether all the requests have been outputted, and if the number is smaller than the number of output requests in the number of output requests registration area 20 of the management table 16, it is determined that there are unoutputted items, and the output is performed again. Returning to step ST5, 2
According to the contents registered in 1-2 and 22-2, digital data is output to the "operation" of the motor with instrument number M (step 5T5).

Thereafter, steps ST6 and ST7 are similarly repeated, but when i>the number of output requests (step 5T7), the process returns to step STI and the same process is repeated again.

Therefore, according to the configuration of the embodiment as described above, all the digital data can be output by one manual operation of the EXE key after selecting a plurality of digital data output points, and the output of the plurality of digital data Even if output requests occur continuously, digital data can be output quickly with simple operations, greatly contributing to improving the functionality of the entire system.
