Embodiment approach 1

[0026] figure 1 It is a figure which shows the structure of Embodiment 1 of the PLC design apparatus which concerns on this invention. The PLC design device 100 according to the embodiment is formed when the computer 10 executes an editing program. The computer 10 is a normal computer including a CPU 11 , a RAM (Random Access Memory) 12 , a ROM (Read Only Memory) 13 , a storage device 14 , a display device 15 , and an input device 16 .

[0027] The CPU 11 reads the editing program stored in the ROM 13 or the storage device 14 and executes the editing program using the RAM 12 or the storage device 14 as a work area, thereby constituting each functional unit of the PLC design device 100 . The storage device 14 is, for example, an HDD (Hard Disk Drive), and stores mechanism configuration information 141 , arrangement rules 142 , and unit information 143 . The mechanism configuration information 141 is information related to the PLC configuration, and includes information requir...

Embodiment approach 2

[0038] Figure 5 The figure which shows the structure of Embodiment 2 of the PLC design apparatus which concerns on this invention. The PLC design device 100 according to this embodiment is different from the first embodiment in that it does not have a unit installation position specifying unit and does not store an arrangement rule in the storage device 14 .

[0039] In the present embodiment, the unit selection / arrangement / input detection unit 112 has a function of detecting, based on the position of the pointer 23, that the pointer 23 is in contact with the CPU unit included in the model 210 displayed in the configuration display area 21. Condition.

[0040] The unit selection operation in this embodiment is the same as in the first embodiment, and is an operation of dragging and dropping a unit in the unit list 220 displayed in the list display area 22 . The unit arrangement operation in this embodiment is an operation of releasing the selected unit to an empty slot of t...

Embodiment approach 3

[0051] Figure 8 It is a figure which shows the structure of Embodiment 3 of the PLC design apparatus which concerns on this invention. The PLC design device 100 according to the present embodiment is different from the first embodiment in that the storage device 14 does not store arrangement rules.

[0052] The unit selection operation in the present embodiment is an operation of dragging a unit in the unit list 220 displayed in the list display area 22 as in the first embodiment. The unit arrangement operation in this embodiment is an operation of bringing the selected unit into contact with an empty slot of the model 210 displayed in the structure display area 21 . In Embodiment 3, after dragging a desired unit in the unit list, touch the pointer to the empty slot where the unit is to be installed, and release it on the CPU where the unit is to be managed, thereby performing unit configuration and parameter setting. .

[0053] In the present embodiment, the unit selectio...

Abstract

It has: an edit screen display unit (111), which displays a list of units available for the PLC on the display device (15), and a unit structure display unit (116), which displays the configuration of the units of the PLC The model of the state is displayed on the display device (15); the unit selection / configuration / input detection unit (112) detects the unit selection operation and the unit configuration operation that are selected from the list of units using the input device (16) unit, the unit configuration operation is to specify the CPU unit on the model by operating the input device (16) while maintaining the unit selection operation; The CPU to be managed by operating the selected unit is determined as the CPU of the CPU unit specified by the unit configuration operation.

Description

technical field [0001] The invention relates to a PLC design device. Background technique [0002] Programmable Logic Controller (ProgrammableLogicController: PLC) is a power supply unit and CPU unit, and units with various functions such as communication units and I / O (Input / Output) units are installed on the base unit according to needs. formed from above. [0003] There is a design environment in which the work of determining which unit is mounted in which slot of the base unit of the PLC can be performed by mouse operation. In addition, in this specification, the work of specifying which unit is mounted in which slot of the base unit is also referred to as "setting the unit configuration". [0004] In addition, there are also PLCs that mount multiple CPU units on the base unit and operate as a multi-CPU (Central Processing Unit) structure. In the case of such a design, it is necessary to determine which CPU unit each unit is managed by. and set it as a parameter. [...
