This article describes how to configure communication with devices using Modbus protocol. Simple and robust, Modbus has since become a de facto standard communication protocol, and it is now a commonly available means of connecting industrial electronic devices (see Wikipedia). Rapid SCADA supports Modbus RTU, ASCII and TCP modes.
This article describes how to configure communication with devices using OPC standard. OPC is designed to provide a common bridge for the software and process control devices from different manufacturers (see Wikipedia). Rapid SCADA supports the following OPC specifications:
- OPC DA (Data Access) to read and write current device data.
- OPC AE (Alarms & Events) to receive event notifications.
Powerful integration capabilities with third-party software are among of the key features of Rapid SCADA. Integrated solutions which include Rapid SCADA and one or more third-party software products allow to perfectly fit customer needs in terms of functionality of the automated system. This article describes the structure of current and archive data and configuration of Rapid SCADA and learns how to integrate with the software.
To add support of a new device type to Rapid SCADA you need to develop the device driver. In terms of Rapid SCADA driver is called a device library or device DLL. SCADA-Communicator application dynamically links up the developed library and performs querying devices and sending telecontrol commands.
