Recent smart factories use OPC as their common communication mode to collect data from the manufacturing facilities. Data collected from OPC Server can be used for monitoring facilities, remote control, data sharing between facilities and equipment using OPC Client. However, the OPC client of OPC Classic is based on COM/DCOM, and has difficulty in firewall setup and security problems when communicating with remote clients. Additionally, the expansion of OPC server data to other platforms is required by the emergence of smart phones, but COM/DCOM is dependent on Windows platform. In this article, we have designed and implemented a remote data communication server/client using WCF as a way to demonstrate functions similar to the OPC UA communication system in the early OPC DA communication system. We have developed a system that can transfer collected data from PLC to remote WCF client, which data gets collected through OPC communication that is for automatic control and monitoring of industrial plant using WCF server. This study is the implementation of a model that can integrate and control PLC data from distributed production sites. This study introduces a model that can be applied to a system that has a limitation to introduce OPC UA, and it implements a method to collect and manage centralized PLC data of distributed production sites. |
