Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field 1] The present invention relates to a programmable controller system, and particularly to a programmable controller having a communication function, and other programmable controllers or control M
This is an improvement in the method for setting information between links, such as the number of connected stations and the number of input/output points, when configuring a programmable controller system by connecting devices.

[Prior art 1 Programmable controllers have traditionally been developed as a replacement for relay m-sequences, or Ike's performance
Programmable controller systems with additional functions or communication functions are becoming more common, and applications are rapidly expanding.

For example, remote input/output line, tf
(hereinafter referred to as remote [/+1 device)] and communication with a general-purpose remote terminal. Generally speaking, the former is an input/output device located at a remote location, but it is a normal collective type l stomach unit. Or, similar to the e:4 quasi-person/output module, it is configured to automatically determine the type of input/output, φ, number type, etc. in the initial cycle or transfer cycle, and communicate. , especially these links t\! on the master station side of the programmable controller. There is no need to set any information.

However, in some cases, the programmable controller itself is a slave station with many input/output points, or the master station checks the connection status of the slave stations, so the input/output points, etc. must be set within the programmable controller. Conventionally, as a method for setting all of these link information, (1) a setting switch is provided.

■Establish a dedicated link area in memory.

etc. were adopted.

[Problem to be Solved by the Invention 1] However, regarding ①, it is possible to avoid increasing the size and price of the device, and in the case of ①, since a special link area is provided, the memory capacity may be limited. Become. Alternatively, since special link areas are set up in advance whether they are currently connected or not, unnecessary processing time is added, and it is difficult to communicate with unconnected areas. There were drawbacks such as a decrease in processing speed.

[Object of the Invention] In view of the above problems, the present invention has been developed to reduce the number of communication areas and stations to 1.
Programmer full Yukon 1 with information on people/output points and links
It is an object of the present invention to provide a programmerful controller conflict system that allows setting to 0-RA easily and inexpensively.

Child Actor 1 for Solving 11 Problems In order to achieve the above object, the present invention provides a programmable controller system in which a programmable controller having a programmable controller function and another programmable controller are connected. The present invention is characterized in that link information including the number of connected communication devices, the type of person/output of each communication device, and the score can be set by a command.

1 Effect] Therefore, by setting the ring information such as the number of connected stations, the type of input/output data, or the number of points, etc. by commands from the programmer full controller.

S can be achieved by using this link information at the start of sequence control to immediately check or exchange input/output data.

[Embodiments of the invention] Hereinafter, the present invention will be described in detail with reference to the drawings.

Figure H1 shows an embodiment of the present invention, where ■ is a programmerful controller, and memory modules 2.
r*x, module 39 communication module 4. It has an input/output module group 78 and other modules 6 such as a power supply module. The part surrounded by the broken line is a general-purpose multiplex transmission system 12, which is used for control and control as ill M.
The module 8 has a transmitter module 98 and a receiver module 10 as slave stations, and a control module 8
'f is connected to the transmitting module 9 and receiving module 10 via a pair of transmitting/receiving lines 11. In addition, the communication line 1 of the programmer full controller 1 and module 4 are also connected to the transmitting/receiving line 11.
It is connected to the multiplex transmission system 12 via.

Here, for ease of understanding, in FIG.
This explains what to do if you are not connected via . The control module 8, the prisoner module 8, and the receiving module 10 communicate data via the sending/receiving-1g line 11 in the O column. Here, in the multiplex transmission system I2 only, addresses are set for each transmitting module 9 and receiving module IO, and the I address is assigned 1 to 11 to a pair of transmitting module 8 and faux Moneur IO. .

The role of each module is shown below. Control module 8 becomes the master station (ff station) that controls 1J31 communications of the entire system, and addresses the 8 sending 1g and receiving modules. : Send. The transmitting module 8 is connected to input devices such as push button switches and limit switches, and when the address sent out by the control module matches the address of the own station, the on/off state of these input devices is changed. is input data, f-checked and sent. The receiving module IO is connected to output devices such as indicator lights, solenoids, and magnets/swifts, and if the sent address matches the address of the own station, it will respond to the sent output data ion/off signal. Convert and output to output device.

In such a multiplex transmission system, when the 'Wf source is turned on, the control module 8 sends out addresses in ascending order, and when it reaches the maximum address of the transmitter/receiver module fftfied to the system, Kl - Repeating the operation of sending from the smallest address, the sending module 9 sends the address of its own station or @
Afterwards, the input data is sent out, and the receiving module 10 at the same address takes in the data into its own station and uses it as output data. Since the communication transmission/reception line 11 can generally extend up to about 1 km, it is possible to wire input/output devices dispersed in remote areas at low cost.

Is it possible to reduce the wiring cost using only such a multiplex transmission system 12?Generally, control is required to perform sequence operations 82 on input signals and output them. Figure 1 shows the most efficient system in such a case, and below we will explain the operation of this system in a programmable manner.
The role of controller l will be mainly explained.

The Brochure Full Controller is a transmitting/receiving module with a number of slave stations. The difference from the configuration of only the multiplex transmission system described above is that 1 is immediately assigned to the communication module 4 in the programmable controller 1 with the same address number as the transmitting module 9 or the receiving module 10. If 3 units are connected and their addresses are '0', 'l' and '2', and if 10 or 2 receiving modules are connected and their addresses are '3' and '4', The address assigned to the communication module 4 in the programmer full φ controller l is '0' as it corresponds to the group of transmitting modules 9.
, “l”, “2”, receiving module 10
"3" corresponds to the group of.

``4''.As mentioned above, in the case of only a multiplex transmission system, the transmitting module ゛°0°°.

"t", "2", receiving module °'0"
, "l", or the address °°2'° has no receiving module, so it becomes an error station.

In such a connection configuration, when power is applied, control unit 8 is in 'o' position.

"l", "2", "3°', "4°', "o"
°.

The addresses are repeatedly sent in the order of "1", "2°", etc. T, 7. Immediately after sending the address "°0°', "1" or °2', each corresponding transmitting module 9 automatically The communication module 4 that converts the input state of the station into serial communication data and sends it out takes in these data, converts them to on/off data, and stores them in a predetermined data memory area T corresponding to these addresses in the memory module 2. Store in. This on/off data is sequentially processed in the same way as when data is taken in from the 6g power module 7 in the programmable controller 1.

Next, address setting or °4″ is sent 1 self (
The module 4 converts the data in the predetermined data memory area corresponding to these addresses of the memory module 2 into serial communication data and transmits the serial communication data. Each receiving module IO corresponding to this address °'3"z or °4°" takes in the data as its own data,
On/off data is f-checked and output.

Looking at the address setting process for each station in such a configuration, if settings are made using a DIP switch and a swift as in the past, the transmission module 98. Nihi Uke 1 Monyur IO can be done by simply setting only the address of the own station.) The communication module 4 in the ``rokrama full controller'' needs to be set for multi-chain addressing, and furthermore, the 7 tres transmission Since it is also necessary to differentiate between settings related to output, that is, those related to reception, that is, large power, if these settings are attempted in the above-mentioned switch I, the Jlcn will become larger and more expensive. Kabanko is also connected.

Therefore, in the present invention, these link information settings are performed using the command language of the block club full controller,
The setting process will be described below.

FIG. 2 shows an example of a link information setting area provided in the data memory area of the memory module 2. In other words, this example shows a part of the existing memory area when the block full controller 1 or the communication module 4 is installed. It can be used as a link information setting area and can be used as an auxiliary memory if the communication module 4 is not installed. In this area, as shown in FIG.
Alternatively, the type of receiving module 50 and the score of Dairyoku or Deba are set as link information.

Figure M3 shows an example of coding the type and number of input Φ output, and by writing +fi from this table into the area of the specified address in Figure 2, the link information can be recognized. Become.

FIG. 4 is an example of a program for writing this code into the area shown in FIG. 2. The block club full controller according to this example is IIJ1 regular no-kense eradication trade order or 710
In addition to requesting pages and subtractions, it is also possible to process link information code transfer commands.

One row is expressed as this command @ “FUN 10°”,
Indicate the numerical value added to that part or the code to be transferred,
Moe followed closely and made a T to instruct the transfer destination. In the case of the program shown in Figure 4, code 1""00°' is located at location 44ooJ in the data memory area, °O1' is located at address 4401,"
l l” is transferred to address 4402.T, that is,
Bro Club Full 9 controller l is at address ゛°O1
゛'s sending Monyur (great power, (A8 points), address”
The transmitting module (16 points) with address ゛°2°゛ and the receiving module (16 output points) with address ゛°2゛゛
・You will be able to recognize the connected depths.

This kind of disconnection is handled by the operator using the “FUN” function.
In response to the input operation of ``FUN 10'', the specified coat is stored in the specified area, or when the system is started, a command is issued prior to the actual control operation. You can do this by searching for “.

In order to perform link information setting and sequence control, the programmerful controller takes in the data from these transmitting modules, executes the programmed sequence arithmetic processing together with the standard input module data, and performs the standard input module data. It outputs data to the receiving module IO along with outputting to the output module. Note that the input data storage address and output data storage address in the programmerful controller l are linked TI! 1
The corresponding storage area may be determined in accordance with the setting of the information setting area. Also, the computation in the block club full φ controller and the communication 18 are performed in parallel in the calculation module 3 and the communication module 4, respectively. The system can be speeded up if it is processed using the following methods.

FIG. 5 shows another configuration example of the programmerful controller system shown in FIG. 1, in which the functions of the control module 8 are added to the communication module 14. Even in such a system, the link information can be set using either the above method or the 6-way method.

Figure 8 shows the system shown in Figure 1 or Figure 5.
Link Tl1 is created by a command other than the fla command explained in the figure.
An example of a program for setting one report is shown below.

In this example, the instruction "FUNII
This is what is supposed to be written into the 7th tres of IJ.

You can use 5 to set the -I barge as mentioned in the explanation of the 4th VJ, so you can now set the link from the input menu of the Bro Club Full Controller, In addition, by changing this data in the middle of the Pochun, it becomes possible to disconnect and santo a by software of each ward reception mozoyule.

Figure 7 and Figure 8 show an example of the link information setting process, and Figure @7 shows an example of the link Tf4 information d9 constant area,
<rl+N is an example of a program. This is designed so that it can be integrated even when a mixed transmitting/receiving module is connected in addition to the transmitting module 9 and the receiving module 10 shown in Figure @1, which are modules dedicated to transmitting or receiving. Therefore, as shown in Figure 7, one or both of the number of blades and the input value are set for one station using a block diagram as shown in Figure 8. This is the same as described with respect to FIG.

FIG. 9 shows another example of link information setting processing for a system to which the above-mentioned transmitting/receiving mixing module is connected, and in this example, no special link information setting area is provided. Here, the processing instruction is expressed as "FtlN 37", and the number placed immediately after that indicates the address of the child S, and the number placed next is the major point number, which is roughly placed after that. Turn the number 1 to indicate the number of output points. Therefore, the second or third
The number 11a or O placed in the ftth position indicates a receiving module or a transmitting module, respectively.

C Effects of the Invention] Prefecture Jl: JAs mentioned above, the present invention allows link information such as the number of stations connected to a programmable controller having a communication function, the Mt type of cutting/cutting data, or the number of points to be connected to a programmable controller having communication functions. Since it is written in the program as an instruction for the programmerful controller, there is no need to set up a link information setting switch, making the system more compact and inexpensive! Ru.

Also, since there is no need to exchange the link information flg as communication data depending on the timing of setting the link information, each part can immediately communicate data at the start of the sequence system iH; ! In addition, when the present invention is applied to a programmable controller system that communicates information, a more reliable programmable controller system can be obtained by comparing and determining set link information and communication data. It can be used as a la system.

In addition, it can be set programmably based on the lick information, making it softer and more versatile.

There is also the advantage of realizing a programmable controller-based system.
