The CAN bus (Controller Area Network) is widely used in different fields of industry and in particular in the car industry,Tthere are a variety of devices, which allow the analysis of data travelling through the bus and generation of messages. The majority of these devices are cards with different formats (PCI, PCMCIA, PXI, etc…) that are finally inserted in a personal computer or rack where data analysis is performed. This article describes a CAN bus monitoring system which allows the analysis and data generation from any PC connected to Ethernet network thanks to the use of a programmable hardware interface which collects the information from the CAN bus and transmits it to any machine requesting this data, using the Ethernet network under a TCP-IP connection. The data monitoring system is extended with the use of OPC protocol (Ole for Process Control) as a tool for secure data distribution to the monitoring and registering systems based on OPC clients.
