Embodiment approach 1

[0039] figure 1 It is a figure which shows the structure of the control system concerning Embodiment 1. The control system 1 comprises an engineering tool 2 and a control device 3 . The engineering tool 2 and the control device 3 are communicably connected via a network N1.

[0040] The engineering design tool 2 creates engineering data including a control program executed by the control device 3 and sends it to the control device 3 . The control device 3 controls the machine by executing a control program included in the project data. As the control device 3 , a programmable controller (JIS B 3502:2011, programmable controllers (PLC)) is exemplified.

[0041] figure 2 It is a figure which shows the hardware structure of the control apparatus concerning Embodiment 1. The control device 3 includes a main board 3a and a sub board 3b.

[0042] The main board 3a includes a CPU (Central Processing Unit) 3a1, a RAM (Random Access Memory) that is a memory 3a2, a communication...

Embodiment approach 2

[0213] Figure 19 It is a figure which shows the structure of the control system concerning Embodiment 2 of this invention. The control system 1A further includes a second control device 3A in addition to the engineering tool 2 and the first control device 3 . The engineering tool 2, the control devices 3, and 3A are communicably connected via the network N1.

[0214] The hardware configuration of the second control device 3A is the same as before. figure 2 The hardware configuration of the first control device 3 to be described is the same, and therefore description thereof will be omitted.

[0215] The control devices 3 and 3A provide a local memory area and a shared memory area in the memory 3a2. The local memory area is an area exclusively owned by the control device 3 or 3A. The shared memory area is an area shared by the control devices 3 and 3A.

[0216] When the first control device 3 writes data to a device in the shared memory area, the written data is transfer...

Abstract

The purpose of the present invention is to obtain a debug device which is capable of simplifying the ascertaining of dependencies among devices. This debug device comprises: a storage unit (24) whichstores project data (24a) which includes a control program which is executed by a control device, and device memory which is data in which descriptions specify a plurality of devices which is a plurality of task regions within the memory of the control device; a display unit which displays text or images; a dependency data creation unit (21a2a) which creates dependency data (24c) which representsdependencies of the plurality of devices which is described within the control program and stores same in the storage unit; and rendering units (21a2b, 21a2c) which cause the display unit to display images which represent the dependencies of the plurality of devices, on the basis of the dependency data (24c).

Description

technical field [0001] The present invention relates to a debugging device, a debugging method, and a debugging program for debugging a control program executed by a control device that controls industrial machines. Background technique [0002] A control program executed by a control device that controls an industrial machine accesses a plurality of work areas in a memory of the control device, that is, a plurality of devices. The control program writes data to another device corresponding to the data of a certain device. That is, there is a dependency relationship between devices. [0003] In the past, when debugging a control program, users needed to open the control program through a program editor to explore the dependencies between devices. [0004] However, the first device may depend on the second device, and the second device may depend on the third device. In addition, there are cases where the fourth and fifth devices depend on the sixth device. In the above s...
