Abstract

PURPOSE:To set the functions of interfaces automatically by reading identification codes out of interfaces in order, and sending and setting information corresponding to the identification codes to the corresponding interfaces. CONSTITUTION:After the power source is turned on, a main processor 1 turns on a function setting mode signal FM. Consequently, the address space of the processor 1 is switched to a function setting mode address space S. At this time, when a function setting strobe signal FS for reading an ID register and setting a function for the function setting mode address space S is turned on, the processor operates on the function setting space of an interface 21 first. Then the ID number of the interface 21 is read in and the kind of the interface 2 is decided according to the contents of the ID to set a necessary function. After the setting is completed, a function setting end signal is turned on and a function setting strobe signal FS is relayed so as to operate on the interface 22 connected as a trailing stage.

This invention relates to an automatic numerical control device.

(Prior art) Various interfaces that make up a numerical control device have address settings, ! There are many elements for setting various functions such as II penetration level setting and control cycle setting. Conventionally, settings for these functions have been performed using switches on the interface, and as the number of functions increases, the number of switch settings increases, leading to the risk of setting errors.

In order to solve this problem, a method has been proposed in which, for some functions, setting contents are placed as information on a data bus instead of on a switch, and this is held in a latch for setting the function.

In order to hold data in 3, each interface 121
, 122, 123 have been set, there is a problem in that the only way to set the address is by setting a switch. In addition, it is necessary to secure a separate address space for controlling the function settings, and if more address space is required due to the expansion of the functions of each ink face 12+, lh, lh, There are cases where it is necessary to modify the function setting program due to a change in the function setting address space that accompanies normal operation booting by partially changing the address space of the
There was a problem in that it was difficult to maintain interface compatibility.

Therefore, in general, there have been problems in the past in that the moxibustion address space interferes with the complexity and erroneous settings in switch settings, and the function settings in program modification and normal operation.

The goal is to provide equipment.

(Means for Solving the Problems) The present invention relates to an interface function automatic setting method for automatically setting functions of an interface for controlling external equipment, and a numerical control device n for automatically setting the functions. and the above object of the present invention is that each of the one or more interfaces has a unique identification code;
A control means connected to each of the ink faces via an address bus and a data bus enables function settings to inhibit normal operation of the interface, and sequentially reads the identification code from each of the interfaces. This is achieved by reading the identification code and sending setting information corresponding to the identification code to the corresponding interface via the address bus and the data bus to set it. It also includes one or more interfaces that are connected to the address bus and the data bus and that control external devices, the address bus and the previous interface, and a controller that issues control commands to the interfaces. a means for digitally chaining each of the interfaces using a control command as a starting point, and indicating that the information of the function setting is valid on the address bus and the data bus; and an identification code line for identification, each of the interfaces having a function setting means capable of handling an identification code for causing the control means to identify the interface, and the control means: The identification code for identifying the machine is enabled, the identification code is read, and setting information corresponding to the identification code is sent to the function setting means via the address bus and the data bus. This is achieved by setting the functions for each interface.

(Function) In the present invention, the control means and each interface are connected by a function setting mode signal line and a function setting strobe signal line, and based on the identification code issued from each interface, By adopting a method of sending setting information to each interface via the control means control bus and data bus, function membrane settings can be automatically performed, for example, when a power supply official is in charge.

(Example) Hereinafter, an example of the present invention will be described in detail based on the drawings.

FIG. 1 is a block diagram of an apparatus according to the present invention.

In the same figure, a main processor 1 connects each interface 2. , 22.23 to control external equipment (motors, operation panels, etc., not shown) (normal operation mode), and function to set functions for each interface 2+, 22.23 (normal operation mode). function setting mode). Each interface 2□, 22.23 is the main
Controls external equipment based on instructions from processor 1,
Further, each interface 2 and the main processor 1 are connected by a signal line which will be explained below. First, address bus 3 is connected to each interface 2 during function setting operation.
Address information for specifying setting items for 1.22.23 is transmitted, and during normal operation, address information for specifying the transfer destination of control command information is transmitted.

Further, the data bus 4 transmits information regarding setting contents for each interface 2□22.23 during a function setting operation, and transmits information for control commands during a normal operation. Furthermore, the function setting mode signal FM is a signal indicating that the function setting operation is in progress, and when this signal is on, normal operation control is prohibited. Also, the identification code FS for machine identification is a signal indicating that information for function setting is carried on the address bus 3 and data bus 4, and this signal is different from other signal lines. The main processor 1 is the starting point and each interface 2 is connected in the form of a digital chain.

FIG. 2 is a detailed circuit diagram of the interface 2 in FIG. This interface 2 is roughly divided into two types: a function setting dedicated circuit and a normal operation circuit. Therefore, first, the function setting dedicated circuit is the identification code receiving/relay circuit 21 for machine identification. mo'e setting mode decoder (DI) 22
, Function setting completion signal generation circuit (FFl) 23 , ID
Register (old) 24 and function setting latch (Ll) 25
It consists of Reception of identification code for machine identification/
The relay circuit 21 receives the identification code FS for machine identification from the main processor 1 or the front-stage interface 2, and if the interface 2 has not completed the function setting, it identifies the machine. The identification code FS is sent to the function setting mode decoder 22 and is not relayed to the next stage interface 2. After that, when the function setting is completed and the function setting completion signal FC turns on, the function setting strobe is activated! +FS is relayed to the next stage interface 2 and operates so as not to be sent to the function setting mode decoder 22.

Furthermore, theory J! l! It is composed of elements 211, 212, and 213. When the function setting mode decoder 22 receives the identification code FS for machine identification from the function strobe 3 recipient reception relay circuit 21 while the function setting mode j+Fu is on, it is loaded onto the address bus 3. decode the received address data. It does not operate when the function setting mode signal FS is off, that is, in the driving operation mode. The function setting completion signal generation circuit 23 generates a function setting completion signal C when the main processor 1 accesses a certain address after the function setting of its own interface 2 is completed. In addition, when 'Jakugen is immersed, it is reset and the function setting completion signal F
C is always off.

The ID register 24 is a register that stores rD that identifies the type of interface 2 sent to the main processor 1. This 10 has a fixed part that is uniquely determined by the type of board, and a variable part that is determined by the equipment connected to the outside, and the latter is variable depending on the state of the manual part of the connector for connecting to the outside. The function setting latch 25 is used by the main processor 1 to store data.
Holds information for function settings carried on the bus 4,
The signal is outputted to a signal switching circuit (not shown) such as a data selector, or as an address decoding condition for the normal operation mode decoder 26 to set an address, an interrupt level, etc. On the other hand, the normal operation circuit 1 consists of a normal operation mode decoder (D2) 25 and a circuit (not shown) necessary for normal operation, and when the function setting mode signal FM is on, the address decoding operation is prohibited. It has become.

FIG. 3 is a flowchart showing the operating procedure in the present invention. Further, FIG. 4 is a diagram for explaining the address space in the present invention.

So, first of all, power supply 1! Main processor 1Sl
),, As a result, the main processor 1 shown in FIG.
The address space is switched to the function setting mode address space S. At this time, a function setting strobe is used to read 10 registers to the function setting mode address space S and perform function settings. When you turn on FS,
The first is interface 2. It acts on the function setting space 11 of . Next, the ID number stored in the ID register 24 is read (step 52). In step S3), it is determined whether the read number is FC1+ (which can be specified arbitrarily), and if it is not FF)I, the type of interface 2 is determined based on the contents of TD and the necessary Perform function setting (step S0°) After the setting is completed, a command is given to the function setting completion signal generation circuit 23 to turn on the function setting completion signal FC (step S5).As a result,
The identification code FS for machine identification is relayed so as to act on the interface 2 connected to the next stage. Below, the operation from step S2 is repeated, but all interface 2 function settings have been completed. Since the signal line of the bus 4 is pulled up by the resistor 5 so that it becomes logic 1, the IO input +α is [F)1. Therefore, in step S3, the main processor I determines that the settings for the currently installed interface 2 have been completed, and turns off the machine IF=setting mode signal M (
Step 58). After that, the address space of main processor 1 is switched to normal operation mode address space T)
The machine can then be controlled via the respective interface 2 set to the desired function.

(Effects of the Invention) As described above, the interface function automatic setting method of the present invention automatically performs the interface function setting and the numerical control device that automatically performs the setting, the switch setting Since there is no need for Kashen C, troubles caused by incorrect settings are completely eliminated, and since the address space is completely divided between the function setting mode and the normal operation mode, the influence of the change in the electric operation mode is eliminated. The influence of specification changes in the function setting mode can be reduced.
