JPS61125663A - Loading system for control program of system constitution device type - Google Patents

Abstract

PURPOSE:To attain an easy, quick and accurate loading system for control program by transmitting a command for detection of the printer type from a main body device to give the type name of the printer as an answer and selecting a PRT-FCP corresponding to the device type name obtained at an identification part within an initializer to load it on a memory. CONSTITUTION:In a system loading more, an initializer 3 transmits an inquiry command (1) for device type to a printer 7. The printer 7 confirms the command (1) through a device type control program (incorporated into a memory ROM8) stored in each printer 7 and gives a response (2) in the from of the device type name stored in a device type data store part 6. An identification part 9 retrieves and reads the corresponding one of PRT-FCP1-PRT-FCPn stored in a disk file 2 through a device type data store part 6 and the response (2). Then the selected PRT-FCP is loaded (3) on a memory RAM5.

Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention provides a system configuration model that can easily load file control programs for each input/output device that constitutes the system into the main storage area of the main unit. Regarding the loading method.

With the development of information processing devices, their usage has become more sophisticated and complex, and a good example of this is the construction of information processing systems in various places that process data by connecting various input/output devices to the main unit. I've started to feel that way.

In particular, printer devices are required to freely display various types of data on paper depending on the purpose of use, and many types have been developed in order to use different processing speeds, printing methods, etc. depending on the purpose. It has been put into practical use.

As the use of information processing systems advances.

Constituent input/output devices, especially printer devices, etc., are often replaced or added.

As a main unit that supervises and controls such an information processing system, it is necessary to always know the types of devices that make up the system, and it is hoped that a means to easily and without errors will be put into practical use. has been done.

[Prior Art and Problems to be Solved by the Invention] As a prior art, a procedure for loading a file control program of a printer device constituting an information processing system will be explained as an example.

FIG. 2 is a block diagram showing a control program loading method for a conventional printer device.

The random access memory 4 (for example, a memory composed of CMOS cells) has a built-in backup battery, and is provided with a model information table 45 of the printer devices that make up the system. Each time the configuration model is changed or added, model data is set externally using a predetermined tool (not shown).

The conventional printer control program loading method uses one initializer 3 that controls system loading.
reads the fixed address determined for each device of the printer device stored in the memory 4, that is, the model information table 45, and uses the model data storage section 6 in the vinylizer 3 to determine the address of the printer device connected to the main device 1. Determine the model,
The file control program for the printer device of the applicable model (hereinafter referred to as PRT) stored in disk file 2

PRT-FCP is a program compatible with each applicable model.

That is, it is assumed that PRT-FCPI=PRT-FCPn is stored in disk file 2.

However, in the conventional method as described above, 3 model information table 4
In step 5, you must have used a designated tool to make settings each time you added or replaced a printer.

In addition to being time-consuming, there were problems such as a high probability of making a setting error.

[Means for solving problems]

An object of the present invention is to realize a new control program loading method for system configuration models that solves the above-mentioned problems.

a reply means for returning the model of the input/output device when inquired by the inquiry means; and a reply means for returning the model of the input/output device according to the model-specific data stored in the main unit and the model returned by the reply means. and an identification means for identifying the
This problem is solved by the system component model control program loading method according to the present invention, in which data for controlling the model identified in the reply when the identification means inquires about the input/output device is stored in an executable area provided in the main unit.

[Effect]

That is, the main unit sends a command to sense the model of the printer to the mechanism control program built in each printer, the model name is sent as a response, and the identification section in the initializer responds. By selecting the PRT-FCP corresponding to the received model name and loading it into memory (RAM), loading can be performed easily, quickly, and reliably.

〔Example〕

The gist of the present invention will be specifically explained below with reference to an embodiment shown in FIG.
