It is foreseeable, that the real-time control of machines still will be implemented directly with event controlled real time capable field buses for a longer period of time. Therefore linking the control network over a gateway to office or automation networks or to the Internet at all via TCP/IP is an interesting and cost-effective solution.
On the EtherCAN CI-ARM9 an Embedded LINUX™ operating system is installed. Therefore a lot of services like FTP, Telnet or an integrated web server but also a RS-232 interface are available to run user-specific applications.
For own developments a Developer Package is available. It includes besides tools to generate the FLASH image, a cross compiler and necessary libraries. Further examples in C, Java or Tcl can be downloaded from our web site www.port.de.The usage of the CANopen Library is possible to create CAN- open applications. Of course ready-to-run programs are available.For the usage as gateway to CANopen based systems the CANopen Server m4d running on the EtherCAN realizes the complete handling of the CANopen protocol. It runs as a Network Management Master, can configure LSS slaves with the LSS commands and supports the following CANopen services:
- NMT Services
- Heartbeat, Node Guarding
- SDO Services including Domain Transfers
- PDO Consumer and Producer
- SYNC Producer
- Emergency Consumer
Cyclic services like SYNC of Heartbeat are handled autonomously.
As protocol between a client application and the CANopen Server the CiA specification DSP309-3 is used at the Ethernet side.
For a comfortable handling of the CANopen Server the platform independent and graphical application CANopen Device Monitor can be used.
For CAN based systems without High-Layer protocol the EtherCAN CI-ARM9 provides the CAN server horch that can send all received data via a TCP/IP port to other applications.
Sending CAN message via the CAN server is possible, too. In the easiest case the server is used as a CAN analyzer via Ethernet. The CAN Analyzer CAN-REport can be used for this.
