In this figure, when the operation is started, first, in step 41, it is checked whether or not there is a dedicated program in the dedicated program memory 31 in the dedicated module.
If there is no dedicated program, it is determined that the dedicated module is not connected, so the routine proceeds to the routine 42, performs error processing, and ends the processing. If there is such a program, the process proceeds to step 43 to set the address of the dedicated program, and proceeds to step 44 to check whether or not there is a dedicated circuit in the dedicated module. If there is a dedicated circuit, proceed to step 45 and set its type and I / O address. Here, the MPU 21 constitutes determination means G for determining the connection state and type of the dedicated module in steps 41 to 45. After these processes are completed, or if there is no dedicated circuit, the process proceeds to step 46, where the dedicated module unit is used.
Check if there is dedicated screen data in 13. If there is the dedicated screen data, the process proceeds to step 47 to set the address of the dedicated screen data. If not, the address of the standard display screen data in the base module 12 is set in step 48 to display the operation state image. Dedicated module
If 13 is a timer module, for example, the seventh
A standard display screen is displayed on the liquid crystal display 6 based on the operation state image data for the timer as shown in FIG. The time display section in FIG. 7 (a) displays the current time, and below it the set time. After displaying this standard screen,
Proceeding to 49, the input / output interface of the base module 12 and the input / output interface of the dedicated module are initialized. Then, the program of the connected dedicated module is started.

8 (a) to 8 (d) are flowcharts showing the operation when a timer module is connected as a dedicated module. In this figure, when the operation is started, first, in step 51, the timer IC 32 is initialized, and the process proceeds to steps 52, 53, where a start signal is given from the outside,
Or check whether there is a key input. As shown in FIG. 7 (a), if the preset key area in which the set value is displayed as 0 second is pressed, the routine proceeds from step 54 to routine 55 to perform preset processing. In the preset process, as shown in the flowchart of FIG. 8D, the condition setting image of FIG. 7B to be time-set in the display memory 25 is read out and displayed on the liquid crystal display 6 (step 6).
1). Then, in steps 62 to 65 of FIG. 8B, it is checked whether any of the mode key, the time set key, the cursor movement key, and the numerical key are pressed.
If the mode key is pressed, the mode set processing routine 66
And a mode selection display is performed as shown in FIG. 7 (c). At this time, if any one of the modes is selected, display of the mode and confirmation processing of the set are performed as shown in FIG. 7D, and if confirmation is made, the process proceeds to steps 63 to 65 to depress other keys. Wait for. If the cursor movement keys ">>" and "<<" are pressed, the digit of the numerical value to be set is moved, and if the numerical key for raising or lowering the numerical value is pressed, the process proceeds from step 65 to step 68 to increase or decrease the numerical value. In this way, if the set time is displayed, for example, 200 seconds and the set key is depressed, the process proceeds from step 63 to step 69, and a timer set confirmation display of 200 seconds is performed as shown in FIG. 7 (e). If there is a confirmation input here, the time is stored in any of the memories and the timer setting process is performed, and the operation proceeds to the operation state image in which the set time is set to 200 seconds as in FIG. 7A. Then the routine goes to the loop of routines 52 and 53,
If the reset key is pressed, the process returns to the initial state from step 56. If a start signal is given from the outside via the input / output connector 15, the routine proceeds to the routine 57 from the step 52 and the MP
The process returns to the loop of steps 52 and 53 of the timer IC circuit from U21.
Here, the MPU 21 has achieved the function of the operating condition setting means I for setting the operating conditions by key input in steps 53, 54 and routine 55.

If there is a timer interrupt every predetermined time as shown in FIG. 8B, the current value is rewritten in step 71, and the display of the current time area in FIG. 7F is sequentially incremented to display the operation state. . At this time, as shown in FIG. 7 (f), the display area between the set time and the current time is an analog display area, and a straight line is sequentially extended from the left end to reach the right end. It can also be displayed to arrive. If the set time is reached and there is a time-up interrupt, the time-up process is performed in the routine 72 as shown in FIG. 8 (c). In the time-up process, a predetermined display is performed on the timer display surface, and an output corresponding to the setting mode is provided from the output connector 10 to the outside. At this time, the light emitting diode of the backlight may be turned on and off behind the liquid crystal display, or when the light emitting diode is a two-color diode, the display color may be changed. Here, the MPU 21 achieves the function of the operation control means H for controlling the timer IC in steps 52, 58, 71 and routine 72.

A case where a counter dedicated module is connected as a dedicated module will be described. This module is a timer
Instead of the IC, an IC for a counter that counts pulses supplied from the outside is connected. FIG. 9 is a flowchart showing the operation of the dedicated module, and FIG. 10 is a diagram showing a display surface thereof. When the operation starts, the MPU 21 of the base module 12 first checks the connection of the dedicated module and determines the type in the same manner as in the flowchart of FIG. 6, sets the display address and the like, and first sets the display address as shown in FIG. 9 (a). Displays the operation status display screen of the counter. And step
At 82 and 83, a start signal or key input is awaited. Similarly, if the preset key is depressed, a count value set screen which is a condition setting image is displayed as shown in FIG. 9 (b). In the process of the preset mode, the mode is selected and confirmed in the same manner as the process shown in FIG. 8B, and the count value is set by moving the cursor and inputting the numerical keys, and the confirmation is completed. In this way, for example, if 1450 counts are set as shown in FIGS. 9 (e) and 9 (f), the process returns to the process shown in FIG. 10 (a) and waits for an external start signal from the connector 15. If the start signal is given, the process proceeds to step 88 to start counting by the counter, and counts an externally applied input pulse.
Every time an input pulse is applied, the current value is rewritten by an interrupt as shown in FIG. 10 (b) (step 8).
9). When the current value reaches the set 1450 count, a count-up process (routine 90) is performed by an interrupt process as shown in FIG. 10 (c). The count-up process is performed by displaying a count-up display on the display surface and by giving a count-up output to the outside according to the output mode.

Next, an operation when a temperature adjusting module is connected as a dedicated module according to the present embodiment will be described.
The dedicated module for temperature adjustment is a dedicated program memory that stores the temperature setting procedure and the temperature control procedure that provides a control output corresponding to the input, and converts the signal from an externally connected sensor into an electrical signal and converts it into a digital signal. Convert to value
The sensor circuit provided to the MPU 21 is a dedicated circuit. When the operation is started by inserting the dedicated module, the operation according to the flowchart shown in FIG.
As shown in FIG. 5A, an operation state image showing the current temperature and the set temperature and the upper and lower limit values below the current temperature is displayed. And the second
When the control program is started as shown in FIG. 12, first, in step 91, initialization is performed and an interrupt is awaited.
If there is a setting change interrupt, the process proceeds to steps 92 to 94 to check whether either the set key or the upper / lower limit key has been pressed. If the set key is pressed, Fig. 11 (b)
A set mode screen is displayed as shown in (1), and numerical value setting or mode setting is performed in the same manner. If the set key is pressed, the process proceeds to step 95 to check whether the mode key is pressed. If the mode key is pressed here, the process proceeds to the mode change process of the routine 96, for example, a mode change process such as switching the unit to Celsius (° C.) or Fahrenheit (ΔF). If the mode key is not pressed, step 95
The routine further proceeds to a routine 97 to change the set value using the numerical keys, and to confirm the set temperature as shown in FIG. 11 (d). When the confirmation is performed, the process returns to the main routine of FIG. 12 to display the current temperature and start the operation. If the upper and lower limit setting keys are pressed, the routine
The process proceeds to steps 98 and 99, and the upper and lower limit alarm values are changed using the numerical keys as shown in FIGS. 11 (f) and 11 (g), thereby completing the upper and lower limit value changing routine. Then, when the operation is started, an interrupt is again waited, an input from an external sensor connected via the connector 15 is taken at predetermined time intervals, and a temperature control signal corresponding to the current temperature is output as an operation amount (step 10).
0,101). Also, the routine proceeds to the routine 102 by interruption every predetermined time, and displays the current temperature and the like. In this way, a control device having various different functions can be realized by variously switching the dedicated module in the case having the same base module.
