摘要
为实现DCS对CAN总线设备的互联,对CAN总线及接口设备进行了研究,提出采用CAN网关设备将CAN总线信息转为Profibus-DP总线信息,并通过ECS-100的DP总线接口卡对CAN网关设备进行设置的方法,实现DCS对CAN总线设备的监控。实际应用表明,采用Profibus-DP总线通信的方式对CAN总线设备进行监控,实现了数据的交互,满足CAN总线设备对数据安全、高效的通信要求。
In order to realize interconnection between DCS and CAN bus devices,the CAN bus and interfacing devices are researched.The method of using CAN gateway device to convert CAN bus information into Profibus-DP bus information,and via DP bus interface module of ECS-100 to setup CAN gateway device to implement monitoring CAN bus devices from DCS is proposed.The practice indicates that this method implements data interaction,and meets the requirements of CAN bus devices upon data safety and high efficient communication.
