Abstract

To collectively set multi-CPU parameters included in a project of each CPU having a multi-CPU relationship, a parameter setting device includes: unit configuration information used for managing, for each PLC, unit information in which a CPU and a project allocated to the CPU are associated with each other; a unit-configuration analyzing unit that extracts a list of unit information on CPUs provided in a same PLC that includes a CPU specified by a user from the unit configuration information; and a parameter writing unit that acquires each project of CPUs provided in a same PLC that includes the CPU based on the extracted list of unit information when a parameter of a project of the specified CPU is set, and sets a setting content, which is same as a setting content regarding a project of the specified CPU, to each of the acquired projects.

Claims

1. A parameter setting device that sets a parameter of a plurality of projects for respectively operating a plurality of CPUs provided in a programmable controller (PLC), the parameter being required for the CPUs to operate in conjunction with each other, with respect to each of the projects, the parameter setting device comprising:

unit-configuration-information storage unit that stores unit configuration information used for managing, for each PLC, unit information in which a CPU and a project allocated to the CPU are associated with each other;

a unit-configuration analyzing unit that extracts a list of unit information on CPUs provided in a same PLC that includes a CPU specified by a user from the unit configuration information; and

a parameter writing unit that

acquires each project of CPU units, which are provided in a same PLC in which the CPU is included, based on the extracted list of unit information, when a parameter of a project of the specified CPU is set, and

sets a setting content, which is same as a setting content regarding a project of the specified CPU, to each of the acquired projects.

2. The parameter setting device according to claim 1, further comprising a consistency checking unit that checks consistency of parameters between the plurality of projects by comparing parameters set to projects of CPUs provided in one PLC with each other.

3. The parameter setting device according to claim 1, further comprising a project-usage-status checking unit that checks whether each of acquired projects is being used, before setting the setting content to each of the projects acquired by the parameter writing unit.

4. The parameter setting device according to claim 1, wherein the CPU is a CPU unit and/or a motion CPU unit.
