The / O section 52 is provided.

The monitor device 60 includes a CPU 62, a communication section 64 for communicating with the controller 40,
A basic function unit 66 that performs screen display, key state input, cursor control, read / write of the monitor memory unit 68 and I / O unit 70, a monitor memory unit 68 that stores attribute data of the monitor device 60, and an I / O unit 70. Is equipped with. A display device 72 such as a liquid crystal display device, a speaker 74, etc. are connected to the I / O unit 70.

<Control Procedure> In the above equipment control device,
The controller 40 controls the operation of the equipment, communicates between the controller 40 and the monitor device 60, and receives information from the controller 40 from the monitor device 6.
It can be displayed at 0.

The control procedure in the equipment control device will be described below.

<Initialization Processing> (Step 1) When the monitor device 60 connected to the controller 40 is powered on, the attribute data stored in the monitor memory unit 68 is transmitted to the controller 40.

(Step 2) The controller 40 creates a device data table based on the attribute data transmitted from the monitor device 60 and stores it in the controller memory unit 50.

As shown in FIG. 2, this device data table is a table in which the hardware characteristics of the monitor device 60 are developed. For example, the value of "disp_area_x" representing the horizontal byte number of the screen display area is " Four
"0", "dis" indicating the number of bytes in the vertical direction of the screen display area
The value of “p_area_y” is “20”, and the value of “key_layout” indicating the type of key is “0, 1, 2, 3, 3.
4, 5, 6, 7, 8, 9, ... ", the value of" mem_area_L "indicating the lower limit address of the data backup area is" 10000H ", and the value of" mem_area_H "indicating the upper limit address of the data backup area is" 2 ".
0000H "," I / O "that indicates the I / O address of the beep sound
Device data with a value of "O_Beep" such as "20H" is expanded. Actually, each memory value shown in FIG. 2 is continuously stored from a predetermined address of the controller memory unit 50.

<Monitor Screen Display Processing> (Step 3-1) In the monitor control program section 46 of the controller 40, the contents to be displayed on the monitor device 60 are written in the screen image area as a virtual device data image, and the DISPLAY flag is set to "1". ”Is set. The data displayed on the monitor device 60 is ASCII data.

This screen image is, as shown in FIG.
Resources such as memory and I / O of the monitor device 60 are mapped to the controller memory unit 50. In addition,
The screen image area is secured for each basic function of the monitor device 60. Further, standard hardware characteristics of the virtual device such as the screen size may be uniquely determined.

In this screen image, for example, when it is desired to display "A", "B" and "C" from the upper left of the monitor screen, as shown in FIG.
"A" is copied to "0" and the memory address is "1001"
To the memory address "1002" and "C" to the memory address "1002". When nothing is displayed on the screen, all areas are filled with "20H" (space for ASCII code).

(Step 4-1) The virtual / actual device data converter 48 of the controller 40 uses each modif
Whether or not the y flag is set to "1" is constantly monitored, and the processing corresponding to each modify flag is performed. The modify flag includes a DISPLAY flag, a KEY flag, a MEM_W (memory write) flag, a MEM_R (memory read) flag, and an IO flag.

For example, when "1" is set in the DISPLAY flag, the data in the screen image area is transmitted to the monitor device 60. In this case, when the screen size of the actual device data is larger than the screen size of the virtual device data of the controller 40, the data is transmitted to the monitor device 60 as it is. On the other hand, when the screen size of the actual device data is smaller than the screen size of the virtual device data of the controller 40,
First, "disp" which is the screen size of the actual device data.
_Area_x ”x“ disp_area_y ”data is transmitted, and when the cursor movement key (“ ↑ ”“ ↓ ”“ ← ”“ → ”) of the monitor device 60 is pressed, the screen image area is displayed as“ disp_area_x ”x“ disp.
The data in the screen image area is transmitted to the monitor device 60 by moving it up, down, left and right in the range of “_area_y”. In this way, the area that cannot be displayed on the screen of the monitor device 60 can be scroll-displayed.

Basically, the controller 40 controls the monitor device 60 by repeating the above step 3-1 and step 4-1.

<Sensing of Key State of Monitor Device> (Step 3-2) When the virtual / real device data converter 48 of the controller 40 polls the monitor device 60 and there is a change from the previous key state. Then, "1" is set in the KEY flag, and the received key change is reflected as a virtual device data in a predetermined address of the keyboard image area after referring to the keyboard template.

For example, as shown in FIG. 4, when a keyboard image and a keyboard template correspond to each other and "1" is set to a predetermined address in the keyboard image area, the key corresponding to the predetermined address is If it is pressed and "0" is set,
It means that the key corresponding to the predetermined address is not pressed. In the example shown in FIG. 4, since the address “1222” is set to “1”, the address “1222” is set.
It can be seen that the "9" key corresponding to is pressed.

In the keyboard image, by allocating each key to a bit instead of a byte, the used memory can be saved to 1/8 (1 byte =
For 8 bits).

(Step 4-2) The monitor control program section 46 of the controller 40 constantly monitors the KEY flag. When "1" is set in the KEY flag, the keyboard image area is referred to, Extract the difference from the contents that were referenced last time and change it from "ON" to "OFF"
Alternatively, it is possible to know the key that has changed from “OFF” to “ON”. When the reference of the keyboard image area is completed, "0" is set in the KEY flag.

Normally, the key is changed from "OFF" to "O".
If it changes to "N", the screen display changes corresponding to the key, and therefore the processing shifts to step 3-1 and step 4-1 described above. For example, the key "1" is "OF
When changing from "F" to "ON", the parameter image is displayed.

<Memory Writing Process of Monitor Device> (Step 3-3) In the monitor control program unit 46 of the controller 40, the data to be written in the monitor memory unit 68 (the first 4 bytes represent the start address).
First, the memory image area is written as a virtual device image, and “1” is set in the MEM_W flag.

This memory image reflects the memory contents of the monitor device 60 as shown in FIG.
For example, one page is 512 bytes, and writing or reading is performed in page units.

(Step 4-3) The virtual / real device data converter 48 of the controller 40 constantly monitors whether or not the MEM_W flag is set to "1", and the MEM_W flag is set to "1". If it is, the value of mem_area_L is less than or equal to the start address, and the value of 512 bytes for one page added to the start address is less than or equal to the value of mem_area_L, and then the data in the memory image area is monitored. Send to device 60. When the transmission of the data is completed, "0" is set in the MEM_W flag.

<Memory Read Process of Monitor Device> (Step 3-4) In the monitor control program unit 46 of the controller 40, the head address of the monitor memory unit 68 to be read is written in the head 4 bytes of the monitor memory unit 68, and MEM_R. Set "1" to the flag.

(Step 4-4) The virtual / real device data converter 48 of the controller 40 constantly monitors whether or not the MEM_R flag is set to "1", and the MEM_R flag is set to "1". If it is, the value of mem_area_L is less than or equal to the start address, and the value obtained by adding 512 bytes for one page to the start address is less than or equal to the value of mem_area_L. Data of 512 bytes (start address + 511 bytes) is received from the start address of the unit 68, and the data is written in the memory image area. When the writing of the data ends, “2” is set in the MEM_R flag.
Set.

The monitor control program section 46 of the controller 40 monitors that the MEM_R flag is set to "2". When the MEM_R flag is set to "2", the data in the memory image area is Reference (or copy to another area) and set "0" to the MEM_R flag. In the above-described embodiment,
Although the R / W (read / write) unit of the memory is described as 512 bytes, the R / W unit of the memory may be variable. In that case, it is necessary to add the byte length after the top address of the head of the memory image area.

<I / O Writing Process> (Step 3-5) In the monitor control program section 46 of the controller 40, the I / O section 70 of the monitor device 60 is used.
When it is desired to control, the corresponding address in the I / O image area is set to "1" and the IO flag is set to "1".

As shown in FIG. 6, this I / O image corresponds to addresses and I / O control. For example, a beep sound corresponds to an address "1752" and a cursor inversion corresponds to an address "1753". And the non-display of the cursor corresponds to the address “1754”. For example, when a beep sound is generated by the monitor device 60, the I / O
The corresponding address "1752" of the image area is set to "1" and the IO flag is set to "1".

(Step 4-5) The virtual / real device data converter 48 of the controller 40 constantly monitors whether or not the IO flag is set to "1". If "1" is set in the IO flag,
Find out the address where "1" is set in the I / O image area, and based on the device data table,
Applicable IO port address (for example, beep I / O
The data for modifying the address 20H) is transmitted to the monitor device 60. After transmitting the data to the monitor device 60, "0" is set to the beep sound address "1752" of the I / O image area, and
Set "0" to the O flag.

<Monitor Control Processing> Controller 40
Performs the monitor control processing of the five patterns of step 3-1 and step 4-1 to step 3-5 and step 4-5 described above while the equipment control program is operating.
