1C31194G02 Master Embedded Module

The 1C31194G02 device driver mainly completes the access to the dual-port memory of the embedded module COM-C, and provides a common driver interface, and the user program accesses the PROFIBUS master embedded module COM-C by calling the interface function.The framework of the Linux device driver is as shown in Fig. 4, and the advantage of this is that, if you want to use other types of field bus (e.g. DeviceNet, CANopen) embedded module COM-C, the Linux device driver does not need to be changed and is directly available.

The 1C31194G02 series control system is a network technology-based control system introduced to adapt to the development of network technology, especially the development of Internet and Web technology. The system integrates the latest fieldbus technology, embedded software technology, advanced control technology and network technology, achieving a variety of bus compatible and heterogeneous system integration. All kinds of domestic and foreign DCS, PLC and on-site intelligent devices can be accessed to the WebField series control system to realise the sharing of process control equipment information within the enterprise.

1C31194G02 management information network adopts universal Ethernet technology for plant-level information transmission and management, and is an information channel for realising plant-wide comprehensive management. The operation network adopts Fast Ethernet technology to achieve data communication between the server and the client and time synchronisation of the nodes of the operation network in C/S mode. The process control network (SCnetII network) realises the connection between the nodes of the operation station and the control station, completes the transmission and sending of information and control commands, and adopts the dual redundancy design, which makes the transmission of information reliable and high-speed.The I/O bus is the internal communication network of the control station, including the field buses such as SBUS, PROFIBUS, Modbus, DeviceNet, and so on.
