Abstract

PURPOSE:To apply a distributed control device to all process controls without generating a control loop by introducing an IC memory, where control loop information is preliminarily formed, into an operation monitor device of the distributed control device. CONSTITUTION:A select key SKEY1 in an operation monitor device POC1 is used to select a control loop stored in a mask ROM and acts upon a CPU1 with a signal SK1. With respect to contents of a memory of this CPU1, a SKEY supporting function SK0 is added in a memory MM0 as shown by a figure A, and a memory MM1 is added newly, and the mask ROM where control loops LOOP0 l1-(n) are stored is provided. IDs a1-an are only designated by SKEY to make generation of control loops unnecessary, and the operation is simplified very much. Thus, various difficulties concerning information processings of control loop generation check, maintenance, etc. are all resolved.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of the Invention for 4U] The present invention relates to a distributed control device, and sometimes to a distributed control device that can be used for Ji without creating a control loop.

[Redundant background]

In recent years, various IFI control devices using microcomputers (μmCPUs) have suddenly become popular, and these devices without μmCPUs are in the process of disappearing. Among these control devices, this proposal is limited to micrometer CPU conversion of various analog controllers such as PID control, which have been used for a long time in the industrial measurement sector, and proposes a distributed control device. It is.

As the glaze adjustment gt function is applied to the μm CPU, the control loop (also called the adjustment loop, for example, the 7th step of adjusting the process temperature, pressure, level, flow rate, etc. to the optimum value for the process + 1ill side 1) Output from human power

It has drawbacks such as:

[Object of the invention] One of the objects of the present invention is to avoid creating a control loop.
If you are interested in a real-time process market, you will be able to use the control device in conjunction with @C.

[Synopsis of the invention]

The advantage of the present invention is as follows. In other words, the performance of this 4m+ city 1 in the junior year is more than enough (control Isome Giant), and the fu control loop itself is sufficient within 50 to 200. +ti! I should be in town.

In addition, in recent years (IC memory (for example, mask R
OM) has appeared and it is possible to apply this to control loop storage. Furthermore, the information capacity of mask ROMs has recently become smaller and has become 1 megabit, so even 20 to 300 bytes/control loop can be packed into one IC package.

Based on such a situation τ, the present invention provides an integrated circuit for controlling the control function by inserting an IC memory that must be installed in the control loop 1 in the operation monitoring unit of the distributed control device. I am trying to create a process that can be used as a base material without creating a J loop.

[Central example of invention zf1M” The following is a continuation of the present Example V.

Furthermore, by combining the control devices e1 to e shown in FIG. 6 with the control devices shown in FIG. 11, it is possible to easily manage the Co information stored in each seedling. That is, 5

In the IC memory stored as L 00 Po, selection is made using all 5KEYs of 1) a I-n of this memory MMI. As a result, ID is added to ao in the illustrated information table Tel in FIG. 12, and a memo! The first part of the JMM operates as a function corresponding to the conventional Co shown in FIG. This control loop is a control loop of tens to hundreds (about 200 control loops is the maximum), considering the number of μm CPUs that have been used over the past ten years.For example, a 1 megabit mask ROM is
If you have enough, you can achieve your goal.

In this way, according to the present example, vJ, for example, mask ROM
If you select one IC memory that stores all the necessary control loops in the IC manufacturing process, the above-mentioned problems will not occur at all, and in some cases there will be a l1lI It does not require any knowledge of group creation and production checking.

In FIG. 13, another embodiment of the invention is omitted.

In the figure, 5KEY2 (second selection KEY) is Kl(Y) that selects I/Ul-n (DIS+n corresponding to this), and is the information selected by this 5KEY2 and the first KEY. SKI!; is stored in the ao of the information table II+, , in the control loop 14 of the city 1j selected by Yx.Therefore, according to the storage capacity of the I/O I

Even if it is distributed to eDIsl-n, it will not lose its functionality.

〔Effect of the invention〕

As explained above, the present invention can be applied to any process 1 [11] without creating a control loop.
