The VScom NetCAN+ 110 is an easy to use gateway from Ethernet to CAN-Bus, based on state of the art RISC components. It provides CAN-BUS communication over Ethernet and WLAN, and allows completely secured communication for both data transfer and configuration to the attached CAN devices. CAN BUS is widely used in industrial applications as well as in automotive monitoring and control. The VScom NetCAN+ can be used to monitor the data traffic as well as sending control information.
Implemented in the NetCAN+ is an option to use the viaVPN system for Remote Access and Monitoring. viaVPN provides secure and strong encrypted access via Internet, without any re-configuration of firewalls. Once installed in the local network the NetCAN+ are used exactly as without the option viaVPN. But at the same time the operation can be monitored from remote locations. If the CAN port is not occupied by local access, also operation from remote is possible.
NetCAN+ supports three operating modes: TCP Raw Server, CAN Bridge and Driver Mode. With TCP Raw Server the communication is handled directly via IP address and port number. The CAN Bridge connects two NetCAN+ devices to tunnel CAN data via Ethernet/WLAN. The Driver Mode requires the installation of a virtual com-port driver, which makes the network fully transparent for the application. NetCAN+ provides various software tools to interface the user application: • The ASCII conversion protocol is useful in developing and testing any CAN-BUS configuration. Users just connect directly via Telnet, and have a simple way to talk to the CAN controller. It can also be used to manually transmit and receive CAN frames. • Applications programmed by users should use the VScan API library (DLL), which transparently handles the ASCII conversion for the CAN frames. Programmers have to handle only the CAN frames and status information, they do not have to care more about the ASCII conversion in their applications. This API is supported in C/C++, C#, VB.NET, Delphi and LabVIEW. • The NetCAN+ also supports CANFestival, an Open Source CANopen Framework. CANopen is a CAN-based higher layer protocol that is used in various application fields, such as medical equipment, offroad vehicles, maritime electronics, railway applications or building automation. CANopen unburdens the developer from dealing with CAN-specific details such as bit-timing and implementation-specific functions. It provides standardized communication objects for real-time data, configuration data as well as network management data. • CANHacker, a tool for analyzing and transmitting frames on the CAN BUS, is included in the product package. This requires the Driver Mode. • A set of Mapper DLLs simulates CAN hardware from other manufacturers. Users configure their system for those products or the NetCAN+ 110 adapter as a replacement. So existing software will use the NetCAN+ without replacing the application or modifying it.
The system viaVPN provides secure and easy access to remotely installed devices. The installation is quickly done and provides convenient tools to get access from all locations
All connections use VPN-tunnels encrypted by SSL and AES-256. And even when remote access to a NetCom Plus Server is possible, this does not provide access to the network the Server is installed in.
Access to the viaVPN Cloud Servers is done like https protocol in a browser. If web pages can be viewed from a location, access to the Cloud is also possible. No re-configuration of firewalls required.
Every capabilities of configuration use the same password including SNMP V3
OpenVPN tunnel provides security on WLAN and Ethernet. The tunnel protects the configuration as well as all serial data. It is also usable across the Internet. Strong encryption by SSL-AES up to 256 bit keys
