Abstract

The route information generation device (100) includes: a tag information storage unit (101) that stores tag information indicating a correspondence relationship between a tag name and the control device (10); a system configuration information storage unit (102) that indicates the control device (10) storing the system configuration information of the correspondence relationship with the network connected to the control device (10); path information, output the generated path information. The path information generation unit (105) receives a first tag name specifying an access destination, specifies a first control device (10) corresponding to the first tag name based on the tag information, and uses the first control device as an access target control device.

Description

technical field [0001] The present invention relates to a route information generation device, a route information generation method, and a program for generating route information used for communication between control devices in a control system including a plurality of control devices. Background technique [0002] Automatic control of equipment in production lines and workshops is usually performed using control devices such as PLC (Programmable Logic Controller) and HMI (Human Machine Interface). In recent years, large-scale control systems in which a plurality of control devices are connected via a network have also been developed. Such a control system may be configured by accommodating a plurality of control devices in one network, or may be configured by connecting a plurality of networks. [0003] Tag names are sometimes used in a control system with multiple controllers. A tag name is a character string associated with a control device. Any character string can...
