Next, the operation of setting start-up information according to the conventional method will be explained using FIGS. 3, 4, and 5.

First, if you want to check the setting information or change the setting contents before startup, enable the power-on stop enable/disable setting switch 44 before turning on the power switch 41 shown in FIG. After that, the power switch 41 is pressed to turn on the power. When the power is turned on, the power lamp 42 lights up. Then, the microprocessor inside the operation unit IO operates to perform an initial diagnosis of the internal hardware resources, and if the result is 0, the normal end screen of step 101 in FIG. 5 is displayed. Next, when the command switch 56 is pressed, the command lamp 55 lights up and the screen moves to step 103, a function selection menu screen. Here, press the hex key switch 59.
Select menus 1 to 5. Under par on the screen indicates a cursor and indicates that a number from 1 to 5 is being input. After pressing any key from 1 to 5, pressing the set switch 57 moves to the corresponding screen. If 1 is specified, the program mode setting screen in step 104 will be displayed. The current 6-digit hexadecimal value and cursor are displayed and the system waits for human input. If you want to change it, press 16 on the screen.
After setting with the advance key switch 59, the set switch 57 is pressed. In this way, by pressing the set switch 57, the contents of the RAM 23 and the contents of each register are rewritten. Thereafter, the process returns to step 103, the function selection menu screen.

When 2 is specified in step 103, the time data input screen appears in step 105, the time and cursor displayed on the screen in step 105 are displayed on the screen, and the screen waits for input.

After the part to be changed is changed using the hexadecimal key switch 59, the set switch 57 is pressed to set the calendar timer 18 of the operation unit IO, and the process returns to step 103 again.

When 3 is specified in step 103, the power control timer enable/disable setting mode of step 10B is entered. Here, the number indicating which one is currently set and a cursor are displayed on the screen and the screen waits for input. If a change is required, press the 1 or 2 key and then press the set switch 57 to set it.

Further, when 4 is specified in step 103, the process moves to step 107, a sub-function selection menu for expansion. If 1 is specified here, the screen moves to the system mode setting screen in step 108, where the currently set value in 2 hexadecimal digits and the cursor key are displayed.If changing, set it with the hexadecimal key switch 59, then switch the set switch. 57 is pressed, it is read internally. If 2 is specified in step 107,
The number indicating the load medium in step 109 and a cursor key are displayed.

In the case of a change, a new input is made using the hexadecimal key switch 59, and the setting is completed by pressing the set switch 57.

After each setting, return to the function selection menu screen in step 103, and select 5 at the end of the settings to return to step 10.

Next, a method of setting startup information when the system has started up and is in operation after power-on will be described.

First, by pressing the command switch 56 in FIG. 4 during operation, the command lamp 55 lights up and the menu screen of step 103 in FIG. 5 is displayed on the general-purpose display 60. At this time, the operation panel 40 is operated independently by the microprocessor 17 inside the operation section 10 without issuing a reset to the entire system. The subsequent settings are made in accordance with the guidance on the general-purpose display 60, similar to the settings made when the power is turned on. After each setting, after returning to the function selection menu screen in step 103, if 5 is selected to end the setting, the command lamp 55 goes out and the setting is completed.

Further, when starting the operation of the terminal control device using this operation panel unattended, power is turned on by a remote power control device (hereinafter abbreviated as RPC) or a built-in power control timer. At this time, the power-on stop valid/invalid setting switch 44 in FIG. 4 is set to the invalid side.

Then, after the power is turned on in the operation unit 10, the power-on stop does not occur and the RA backed up by the battery 21 is activated.
The system is started up using the preset IPL initial setting values stored in M23.

(Problem to be Solved by the Invention) However, in the conventional device with the above configuration, when turning on power to the terminal control device using RPC or a built-in power control timer, the power-on stop enable/disable switch 3 in FIG. was mistakenly set to the valid side, there was a problem in that after the power was turned on, the system entered a power-on stop state and the entire system except the operating section 10 was reset and the system did not start up.

The present invention eliminates the drawback that the system will not start if the power-on stop switch is mistakenly set to the valid side when the power is turned on unattended, and the terminal control prevents troubles caused by erroneous operation. The purpose is to provide equipment.

(Means for Solving the Problems) In order to solve the above-mentioned problems, the present invention provides an IIRAM that stores an IPL initial value, an IPL stored in this RAM,
Startup of a terminal control device consisting of an operation section that has a display section that displays initial values, a switch section, and a control section, and a main body that performs system operations based on a built-in program according to control signals from this operation section. In the IPL initial value setting method, in which the initial IPL value required for the system is set using the operation panel, when the power switch is pressed, pressing and holding the power switch at the same time will keep the main unit in a reset state and instruct you to check/change the initial IPL value. Furthermore, if pressed while the main unit's system is operating, there is a first switch that instructs only to check/change the initial IPL value without resetting the main unit, a second switch that inputs the initial IPL value, and a second switch that inputs the initial IPL value. A third switch for instructing the end of confirmation/change is provided in the switch section.

(Function) According to the present invention having the above-described configuration, when checking/changing information necessary for the initial IPL value when the power is turned on, the first switch is pressed at the same time when the power is turned on. It becomes possible to confirm/change the IPL initial value from the switch section at the same time as setting the main body to the reset state via the switch section. Thereafter, the operator changes the IPL initial value stored in the RAM using the second switch or confirms it on the display. After the confirmation/change is completed, the reset state of the main body is canceled via the control section by pressing the third switch. Then, the main body starts system operation based on the contents of the RAM at this time.

Further, when the power is turned on unattended, the first switch is not pressed at the same time, so system operation is started based on the contents of the IPL initial value set in advance in the RAM.

Therefore, the present invention can provide an IPL initial value setting method that prevents the problem of the system not starting up due to the power-on stop switch being erroneously set to the valid side.

(Example) An embodiment of the present invention will be described below based on the drawings.
