[0007] (a) The above-mentioned interlock diagnosis unit updates and displays whether the interlock condition is satisfied or not. In addition, even if a multi-stage interlock circuit is formed, only the initial factor variable of the failure is determined and automatically displayed in a graphical language. However, this The interlock diagnosis function is only performed for the interlock circuit of the control unit of one device

Embodiment 1

[0059] (Structure of Embodiment 1)

[0060] First, refer to Figure 1 to Figure 3 Embodiment 1 will be described.

[0061] figure 1 It is an overall structural diagram of Embodiment 1 of the present invention, and this Embodiment 1 is roughly composed of four parts. That is, in addition to the controller CON1 as the equipment control unit, the computer COMP as the control program generation and display unit, the general operator operation and display machine HMI (human machine interface device) operated by the operator in the equipment operation room, In addition to the past equipment control system composed of a LAN (Local Area Network) connected to the former, it is composed of multiple controllers CONT2, CONT3, ... CONTn having the same functions as the controller CONT1. These multiple control The devices CONT2, CONT3, . . . CONTn are also connected to the LAN.

[0062]The controllers CONT1, CONT2, CONT3,...CONTn are mainly composed of two parts, including: an object me...

Embodiment 2

[0098] image 3 The lower part of 1 shows Embodiment 2 of the present invention, that is, the [Faulted] column of the interlock diagnosis screen by the interlock diagnosis unit 20 .

[0099] In the above-mentioned embodiment 1, in image 3 In the [Live] column of the interlock diagnosis screen at the lower part, among multiple controllers CONT1, CONT2, CONT3, ..., CONTn that are connected to the network as the equipment control unit, even if the interlock condition used by any controller When an interface is made from another controller as a representative contact, by also monitoring the establishment and non-satisfaction status of each interlock condition established by other controllers as a representative contact, it can be used as a starting point for the failure of the interlock in any controller. Cause contact to display.

[0100] On the other hand, a function is provided in Embodiment 2, which is in image 3 In the [Faulted] column of the interlocking diagnosis scree...

Abstract

An equipment control system comprising: a program editing unit (10) for generating a control program including interlock conditions and interlock diagnosis; an equipment control unit (CONT1) for executing a program object in the above control program; and the above equipment control unit (CONT1) a plurality of equipment control units (CONT2), (CONT3), ... (CONTn) with the same function; with a logic action part and a display part, updating and displaying that the above-mentioned interlocking conditions are at a specified time point before now An interlock diagnosis unit (20) that determines and automatically displays the main cause of the failure even if a multi-stage interlock circuit is formed at the latest failure time in the past when it is established or failed, and is automatically displayed in a graphic language; and an operation operated by the equipment operator The operator operates and displays the machine (HMI), and the operator operates and displays the machine to have the same function as the above-mentioned interlock diagnosis unit (20).

Description

technical field [0001] The invention relates to an equipment control system, in particular to a device for generating, displaying and diagnosing equipment control programs. Background technique [0002] In general, when constructing an equipment control system, the system programmer provides the program for automatically operating the equipment as the control program of the equipment control device to the equipment operator after generating, testing, and debugging. [0003] Here, in order to safely control the equipment, the system programmer must incorporate interlock conditions (permission conditions for machine operation) for starting and operating equipment such as rotary machines in the control program. This is because whether or not the interlock condition is established is definitely a matter of concern to the equipment operator, so it is required to present easy-to-understand information to the equipment operator. [0004] In the past, an equipment system control sy...
