Also, system register monitoring and setting, system setting operations such as I / O allocation status registration, forced set / reset of the contacts of the programmable controller 3 in program mode or run mode, and test operation of the programmable controller 3 etc. There is a function that can be operated.

FIG. 2 shows the configuration of the programming / debugging device 1 of this embodiment. In the programming / debugging device 1 of this embodiment, in addition to the display unit 5 and the operation unit 4, the communication cable 2 is connected. A connector 6, a ROM storing an operation program of the device, a memory unit 7 including a RAM for securing a work area, and a driver / receiver 8 for communication are provided, and display control and operation are performed. C which is the center of the entire device such as key input processing of the section 4, control of writing and reading of the memory section 7, control processing of the driver / receiver 8 and data processing.
It is composed of PU 9.

Here, the operation unit 4 which is an important component of this embodiment has hexadecimal numeric keys ("0" to "0") shown in FIG.
"F") is provided along with other function keys, etc., and each key of this hexadecimal value is a continuous word (or 1 byte) of programmable controller 3 when the function of forced set / reset is activated. One-to-one correspondence is made to each bit of the contact data, and the correspondence relationship between them is preset in the memory unit 7.

Then, when the state where the function of forcibly setting / resetting the contact is operated by the key operation of the operation unit 4 is entered, C
The PU 9 reads the state of each contact of the programmable controller 3 and displays the state of each contact on the display unit 5 as shown in FIG. The display of the display unit 5 is a 16-digit display, and each digit corresponds to the contact one-to-one, for example, from the rightmost digit to No1 to No16 in sequence. The display of "0" indicates that the contact is in the reset state, and the display of "1" indicates that it is in the set state.

When it is desired to change the state of the contact No. 14 from the reset state to the set state, the hexadecimal value key "D" may be operated, and the CPU 9 responds to this operation. The contact data is inverted, and based on this inversion, the state display of the No. 14 contact of the display unit 5 is shown in FIG.
As shown in (b) of (1), data for inverting the state of the target contact of the programmable controller 3 from reset to set is transmitted to the programmable controller 3 through the driver / receiver 8 at the same time.

Next, in order to return the contact No. 14 in the set state to the reset state, it is sufficient to operate the hexadecimal value key "D" again.
U9 inverts the corresponding contact data, and based on this inversion, the state display of the No. 14 contact of the display unit 5 is shown in FIG.
As shown in (1), the data that inverts from “1” to “0” and at the same time inverts the state of the target contact of the programmable controller 3 from set to reset is transmitted to the programmable controller 3 through the driver / receiver 8.

Next, for example, when resetting the contact No. 2 currently in the set state, "2" of the hexadecimal value key
The CPU 9 inverts the corresponding contact data when this operation is performed, and based on this inversion, the state display of the No. 2 contact of the display unit 5 is displayed as shown in (d) of FIG. The data that inverts from 1 ”to“ 0 ”and at the same time inverts the state of the target contact of the programmable controller 3 from set to reset is transmitted to the programmable controller 3 through the driver / receiver 8.

In this way, 1 corresponding to 16 contact points
16 corresponding to each bit of 6-bit contact data
It is possible to set / reset the contact by simply operating the decimal value key.
