Abstract

PURPOSE:To reduce the number of transmission lines and to improve the reliability by performing the communication between a unit, which sets parameters such as a set value or the like of each regulating unit, and a regulating unit, which performs the regulating operation, with a serial digital signal. CONSTITUTION:In a setting unit 3, a transistor or the like is turned on and off by a signal from a central processing unit 60 to transmit set data such as a set value or the like to regulating units 21-28 through a transmission line l1, and input data of regulating units 21-28 are received through a transmission line l2 by a receiving circuit 70, and an address designating signal, which designates one of regulating units 21-28 to which data should be transmitted, is transmitted through a transmission line l3. Since the address designating signal designating one of regulating units 23-28 which should communicate with the setting unit 3 is transmitted from the setting unit 3 through the transmission line l3, the regulating unit (for example, 23) designated by this address designating signal communicates with the setting unit and receives data such as set parameters or the like through the transmission line l1 and transmits prescribed data such as input data or the like through the transmission line l2.

Description

DETAILED DESCRIPTION OF THE INVENTION (1) Field of the Invention This issue 1131J relates to an improvement in a multi-point adjustment device.

Adjustment card (unit) for the number of machines, setting force, -do (unit) -/I! I got angry f! We are proposing an M1 section device.

In such an adjustment device, the adjustment unit performs adjustment operations except for the setting function, and the setting unit sends parameter signals such as set values to the valley adjustment unit along a shim feed line to make settings. .

In this case, if transmission is to be performed using a pass line of a central processing unit such as a microcomputer in the setting unit, an extremely large number of transmission lines will be required. In addition, with such a distributed jliU control device button device, each unit can be safely isolated and operated individually, but if the above-mentioned pass line is used, there will be a large number of isolated locations. .

There is a point in time when Tani University becomes independent and becomes irt.

A changeover switch 235 for local (I,) and manual (M), an output operation switch 236 for manual mode, and the like are provided. On the printed circuit board 231, a part 238237, such as a microcomputer, is formed which compares an input signal with a set value, performs calculations etc. from P, and outputs an adjustment signal.

The setting unit 3 is also called a controller parameter checking card, and is composed of a front plate 3o and a printed circuit board 31, and the front plate 30 has each adjustment unit 21.
. . , display section 3o1 for setting parameters such as arithmetic constants from 28 settings i+'irP. A setting section 302 such as a switch is provided, and the printing board 31 is.

Arithmetic unit 31 for performing the above settings and communicating with the host computer, etc.
0 is provided and connected to the motherboard board 4 and the connector 40, and each tone'B15 unit 21. . . , 28 and the setting unit 3 are seamlessly connected by a common transmission line of the motherboard 4.

In addition, the back of case 1 (the center is each adjustment unit 21°

..., 58. A cable 50 is connected to enable the setting unit 3 to communicate with a host computer or the like by 1M.

Each adjustment card 21. . . , 28, the desired parameters are set by interfering with the common transmission line, and each adjustment card 21 . . . , 28 performs adjustment operations.

Like each adjustment unit 21. . . , 28 are independent except for the setting I, and each receives the calculation output 1 from the input, and the power supply and instructions are also independent. On the other hand, the setting unit 3 is responsible for setting the setting values of each d1 and 4-section unit, setting parameters such as PID constants, and receiving communications from the upper level meter car, rock, etc., and is responsible for better differentiation of 4-year-old functions and reduction of instrumentation costs. We are trying to reduce this.

If the selector switch 235 of the lesson 1j unit 23 is set to manual (M), for example, the operation switch 236 will bring the unit into a nodal operation state.
