CANopen Interface Cards and Boards
CANopen PCI, CANopen PC/104, CANopen PC Card, PCMCIA
Softing offers interface cards in various hardware formats for operating a PC as a CANopen master. You can integrate them in your application either via the standardized OPC interface or by means of the programming interfaces (APIs) available for the cards.
You can use our CANopen OPC Server for connections via OPC. This is available either as an accessory to the CAN interface cards or in an inexpensive package (server + card). Its integrated CANopen Configurator will help you commission your network.
We offer two different APIs:
The "CANopen-API" is optimized for performance and exact protocol timing. Since the protocol is implemented directly in the card's firmware, the CANopen API is particularly well-suited to fast, extensive control tasks.
- CANopen API for Softing's CAN Interface Cards
- CANopen master function
- Protocol is processed directly on the card
- Exact time response with millisecond resolution
- Dynamic creation of PDOs
- Supports acyclic, cyclic, asynchronous and synchronous PDOs
- Time-critical process data is stored in the DPRAM
- Transmission of any amount of data via SDO
- Parallel processing of several SDO requests
- Asynchronous application interface with task and event queues
- Runs under Windows 7/Vista/XP/2000 (32 bit)
CANopen API supports the following CAN interfaces and operating systems:
| Windows | 7 | Vista | XP | 2000 |
|---|---|---|---|---|
| PCI (1-channel) |
||||
| PC/104 (1-channel) |
||||
| PC Card (uses channel 1) |
LeanCANopen is a free add-on to our interfaces with CAN API which realizes CANopen-specific protocol services directly on the PC. It is particularly suited to tasks such as network configuration and device parameterization, but it can also be used for control tasks which are not as time-critical.
- Free CANopen API for Softing's CAN interface cards
- CANopen master function
- Protocol is processed in the PC
- Supports both channels of 2-channel cards
- Time response is determined by the Windows operating system
- Allows one outstanding SDO request each (no parallelism)
- Contains layer setting services
- Runs under Windows 7/Vista/XP/2000 and Linux
- Migration to CANopen API is very easy since the function calls are largely the same
