Pay Less, Save More: Cheaper & Customized HMI Implementation (WS 162)
In this workshop you will learn about two approaches on software communications, namely Dynamic Data Exchange (DDE) and Open Platform Communications (OPC).
A common use of DDE is for custom-developed applications to control off-the- shelf software. For example, a custom in-house application might use DDE to open a Microsoft Excel spreadsheet and fill it with data, through communicating with your equipments.
Open Platform Communication (OPC) is also explained in this workshop. OPC specifies the communication of real-time plant data between control devices, like PLC’s from different manufacturers and developing software like C++. One of the advantages of OPC over DDE is its higher speed and scalability.
Case studies demonstrated in this workshop is based on Rockwell’s RSLinx and Allen Bradley products.
