Now, when power is applied to such an operation display panel, it is checked whether the operation display panel is connected to an external device or an external control device (sequencer), and the result is displayed on the display panel 6b. indicate. Here, when the external device is not connected, the display panel 6
By pressing the transparent switch 6a in accordance with the display on the screen b, the operation display panel enters the function confirmation mode. An example of the display screen at this time is shown in FIG. The operation of FIG. 1 will be described below with reference to FIGS. 2, 3 and 4. First, a function confirmation menu is displayed (S1), and a key input waiting state is set (S2). When the switch lamp display key K1 shown in FIG. 4 (a) is pressed in this state, a screen as shown in FIG. 4 (b) is displayed (S3), and when the data setting monitor key K2 is also pressed, the screen shown in FIG. c)
A screen like this is displayed (S10). Thus, the function of the screen changeover switch, which is one of the functions of the operation display panel, can be confirmed.

Assuming that the screen display of the switch lamp shown in FIG. 4 (b) is displayed, a key input is waited (S4), and when a key input is made, the determination is made (S5). Next, the state data of the switch held in the internal memory 4A is changed (S6), and the switch is displayed based on the state data (S7). As the lamp display, here, instead of monitoring the signal from the outside, the state of the switch is read (S8), and the lamp display is performed based on the state data (S9). That is,
When the pressed switch is the momentary switch MS as shown in FIG. 4B, the switch display is highlighted only while the switch MS is pressed, and the switch state is turned on. Therefore, when the switch is released, the original display is restored and the switch state is turned off. In the case of the alternate switch AS, when the switch is pressed, the switch display is highlighted and the switch state is turned on. Then, when the same switch is pressed again, the display of the highlighted switch is returned to the original display and the switch state is turned off. Further, in the case of the select switch SS, when the switch is pressed, the display of the other select switches is made a normal display to turn off the switch state, only the display of the pressed switch is highlighted and the switch state is turned on. From the above,
You can check the functions of the operation switches and lamps on the operation display panel.

Next, when the key K2 is pressed to perform the data setting monitor in FIG. 2, the process goes to step S10 in FIG. 3, where the data setting monitor screen as shown in FIG. 4 (c) is displayed. It Next, wait for key input (S

2). Here, if the ten-key TK in FIG. 4C is pressed, the cursor is moved and the value of the pressed key is displayed at the cursor position as in the normal operation (S13). If the ENTER key, which is one of the operation switches 8, is pressed, the set value is also stored in the internal memory 4A at this time as in the normal operation (S14). Furthermore, FIG.
If the increment key IK in (c) is pressed,
If the set value in the internal memory 4A is incremented by 1 (S15) and the decrement key DK is pressed, the set value in the internal memory 4A is decremented by -1 (S16). next,
When data is displayed on the monitor, the input data from the outside is read and displayed in the normal operation, but instead of this, the set value in the internal memory 4A is read (S17) and the value is displayed on the display panel. Monitor display (S18). As described above, it is possible to confirm the monitor function for the data setting of the operation display panel.
