Application
The SIMATIC PN/CAN LINK connects a PROFINET network to the CAN or CANopen fieldbus, and enables the data exchange.
This gives the user the option of communicating with up to 126 CAN nodes.
The configuration is made in the TIA Portal V14 or higher. A corresponding HSP is available to the user.
In CANopen mode, external device description files (.eds files) can be imported and exported.
The SIMATIC PN/CAN LINK has an internal PROFINET switch and integrates itself seamlessly into a PROFINET network.
Design
- S7-1200-type enclosure, width 70 mm
- Can be mounted on a standard DIN rail or a control panel
- Connection to PROFINET PN IO networks exclusively via PROFINET by RJ45 connectors
- Connection to CAN Bus via a D-sub connector (9-pin, socket)
- 3-pin connection of the external 24 V DC supply voltage
- Operation without fans or batteries
- LED for visualization of the operating states for CAN, PROFINET and PROFINET ports
- Maximum permissible cable length of the CAN network up to 1 000 m (depending on data transmission rate, cable cross-section, number of participants)
Function
- PROFINET IO device
- Controllers supported: S7-1200, S7-1500, ET 200SP, Open Controller
- Supports 512 receiver and 512 transmitter PDOs
- Baud rate from 50 kbaud to 1 000 kbaud on the CAN side
- Three different operating modes:
- CANtransparent
- CANopen Manager
- CANopen Slave
- Data transmission options:
- After value change / acyclic
- Cyclic (after parameter assignment at first to 240th “SYNC”)
- On request out of the application (RTR)
- Cyclic data exchange between the PN/CAN LINK and the connected SIMATIC S7-CPU via update of the IO image
- Acyclic communication via the “Read/write data record” services
- Easy engineering and extensive diagnostics options due to optimum TIA integration
Configuration
- Configuration or data mapping of the SIMATIC PN/CAN LINK via HSP (TIA Portal V14 and higher)
- CANopen Manager and CANtransparent operating modes (CAN Bus 2.0A/B):
Complete configuration of the PN/CAN LINK in the TIA Portal. External software is not required. - CANopen Slave operating mode
Configuration of the object directory (OD) of the PN/CAN LINK. The OD is then made available to the CANopen Manager with .EDS file export.
- CANopen Manager and CANtransparent operating modes (CAN Bus 2.0A/B):
- Saving the configuration data of the SIMATIC PN/CAN LINK in the higher-level SIMATIC S7 controller, automatic transmission during start up
- Representation of the CAN components as submodules in the TIA Portal. Up to 126 CAN components can be integrated.
- Update mechanisms: TIA Portal and Siemens Automation Tool (SAT)
