CANopen for PROFINET
CANopen support
The CME/PN from Ixxat provides comprehensive CANopen master technology within any PROFINET I/O environment. The device functions as a standalone CANopen Master – a configurable CANopen Master – which exchanges information via PROFINET with a PLC. The CME/PN enables the simple integration of Siemens controllers in industrial sectors where CANopen is used. It also allows PROFINET PLCs to communicate with CANopen fieldbus devices.
The gateway features an integrated 2-port switch, enabling simple integration into PROFINET topologies. The connection to the CANopen bus and the power supply is made using screw terminals. Device configuration and firmware upgrades can be carried out via a USB 2.0 port.
CANopen eigenschappen
- Selection of CANopen manager and CANopen slave devices based on a user configurable device catalog
- Management of any number of device description files inside the device catalog
- Configuration of CANopen manager parameters including NMT startup object, NMT slave assignment, and device type identifications
- Configuration of NMT error control services, both heartbeat and node guarding
- Direct configuration of device parameter objects which are written to the CANopen devices on network startup
- Individual selection of application objects to be mapped into the process image of the CANopen manager
- Alternatively, selection of application objects based on default PDO mapping of CANopen slave devices
- Automated calculation of PDO communication and mapping parameters for both CANopen manager and CANopen slave devices
- Manual manipulation of PDO communication and mapping parameter for CANopen slave devices
- Inspection of the calculated process image and grouping of parameters within the process image
- Manual adjustment of PROFINET timing parameters with estimation of the resulting CANopen bus load
- Generation of concise device description data and direct download of network configuration data to the IXXAT CME/PN
CANopen Manager configuration and STEP 7® integration
The gateway can be easily configured using the Ixxat CANopen Configuration Studio, which is supplied free of charge. The configuration tool automatically generates a CDC configuration file for the CANopen network – which is loaded into the CME/PN – as well as a GSDML file for PROFINET.
The CANopen configuration is based on EDS files. Using a graphical drag & drop interface, SDOs are mapped to PDOs and automatically placed in PROFINET subslots. The GSDML file ensures simple gateway integration into PROFINET networks and enables access to the gateway from PLC applications. The gateway is represented here as a single I/O device. All data on the CANopen side that is exchanged via the gateway with the PROFINET network is defined in the GSDML file as variables with variable name, data size and data direction. This unique two-sided approach significantly simplifies configuration.
