Overview
- For data exchange between an ET 200SP system and CAN Bus 2.0A/B or CANopen Manager or Slave (according to CiA 301 & 302)
- CANopen features:
- Node / lifeguarding
- Heartbeat
- SYNC (producer / consumer)
- Integrated in TIA via HSP, TIA Portal V15.1 or higher
- CAN connection with push-in terminals
- Integrated CAN bus terminating resistor
- Up to 60 CAN nodes
- 128 receiver and 128 transmitter PDOs
- Galvanic isolation between the two networks
- Diagnostic interrupts
- Optionally with function block SIMATIC ECC CHAdeMO:
Realization of digital communication as basis for conductible DC charging of electric vehicles in line with the CHAdeMO standard
Application
The SIMATIC ET 200SP communications module CM CAN is designed to connect an ET 200SP system with the CAN or CANopen fieldbus and enables the data exchange.
This gives the option of communicating with up to 60 CAN nodes.
The configuration is carried out in TIA Portal (V15.1 or higher). A corresponding HSP is available to the user.
In CANopen mode, external device description files (.eds files) can be imported and exported.
Design
- Setup as ET 200SP module with a width of 15 mm
- Use with type “A0” base units
- Connection at CAN bus via push-in terminals on the base unit
- Terminating resistors can be connected by wiring to the base unit
- LEDs for visualizing the operating conditions of the module and connected CAN bus network
- Power supply via backplane bus. No external power supply required.
- Operation without fans or batteries. Maintenance-free.
- Maximum permissible cable length of the CAN network is 1 000 m (depending on data transmission rate, cable cross-section, number of participants)
Mode of operation
The cyclic data exchange between the module and the corresponding CPU or interface module takes place via the backplane bus and by updating the I/O image.
Acyclic communication is via the “Read/write data record” services
CAN components are represented as submodules in TIA Portal. Up to 126 CAN components can be integrated.
The communications module supports 128 receiver and 128 transmitter PDOs.
Function
- Three different operating modes:
- CANtransparent
- CANopen Manager
- CANopen Slave
- Easy engineering and extensive diagnostics options due to optimum TIA integration
- Data transmission options:
- After value change / acyclic
- Cyclic (after parameter assignment at first to 240th “SYNC”)
- On request out of the application (RTR)
- Data transmission rates on the CAN side from 10 to 1 000 kbaud
- Optionally with function block SIMATIC ECC CHAdeMO:
Realization of digital communication between a DC charging station and an electric vehicle as basis for conductible DC charging of electric vehicles in line with the standard CHAdeMO 1.x…2.0 charging mode 4
Configuration
An HSP is available for configuring and data mapping the communication module (TIA Portal V15.1 or higher).
In CANopen Manager and CANtransparent operating modes (CAN 2.0A/B), configuration of the communication module takes place completely in TIA Portal. External software is not required.
In CANopen slave operating mode, the user configures the object directory (OD) of the SIMATIC ET 200SP CM CAN and provides it in the form of an .eds file export to the CANopen Manager.
The communication module configuration data are stored in the higher-level SIMATIC S7 PLC and automatically transmitted during start up. It is not necessary to call up a corresponding function block.
TIA Portal and Siemens Automation Tool (SAT) are available as update mechanisms.
