CANopen® Interfaces for SIMATIC®
Industrial Automation Systems


The CANopen modules by HMS enable system integrators to easily and inexpensively integrate CANopen field devices with SIMATIC industrial automation equipment. The modules allow interaction between PROFIBUS or PROFINET controllers – such as the S7-1200 or ET200S device series – with CAN/CANopen fieldbus devices (gateways).

1 SI CANopen

Plug-in CANopen Master/Slave module for
SIMATIC® ET200S modular I/O system

The 1 SI CANopen module brings CANopen connectivity to the SIMATIC ET200S modular I/O system, enabling full integration between devices on a CANopen network and the ET200S. Furthermore, the addition of 1 SI CANopen module into the ET200S system allows a CANopen network to be seamlessly controlled from PROFIBUS and PROFINET.

With the 1 SI CANopen module HMS integrates its CANopen master technology with the SIMATIC architecture. The 1SI CANopen module enables easy integration of SIMATIC equipment into business segments where CANopen and other CAN based protocols are used today, also opening up the possibility for PROFIBUS or PROFINET controllers such as the S7 series of advanced controller devices to interact with CAN and CANopen fieldbus devices (gateways).

The 1 SI CANopen module is supported by all interface and CPU modules of the SIMATIC ET200S modular I/O sytem, with the exception of the Basic and Compact versions.

Configuration

CANopen configuration and TIA Portal integration

Easy integration into the SIMATIC world is one of the most essential requirements when extending of the SIMATIC automation system with networked fieldbus equipment that is not based on either PROFIBUS or PROFINET. HMS has addressed this need enabling a seamless integration of the 1 SI CANopen module into either SIATIC STEP 7 or TIA Portal. Configuration of the connected CANopen network is intuitively performed with the optional Anybus Configuration Manager - CANopen.

Once the configuration is finalized, the CANopen network configuration may be uploaded to and stored in the PROFIBUS or PROFINET PLC or the ET200S I/O system CPU. If a 1 SI CANopen module has to be replaced, the previously stored configuration can be downloaded from the PLC to the new module, significantly reducing down-times in high availability applications. 1 SI CANopen modules may be replaced while the ET200S is powered.

Technical services

Getting Started Support

We offer our customers support via phone, e-mail and Teamviewer in getting started the quickest way possible. This includes assistance in installation of the gateway, explaining the included programming examples, and giving an introduction to configuration.

Configuration Support

Our experienced engineers can support you in configuring the gateway to fit into your application. This includes analyzing your system setup and requirements, adapting the configuration of the gateway, optimizing your PLC program and configuration. Communication is usually via e-mail, phone and Teamviewer. Optionally we can offer to come to your site and work with your engineers directly at your system.

CAN 2.0A mode

Transparent CAN 2.0A functionality with the 1 SI CANopen

With the transparent CAN functionality, the 1 SI CANopen module allows transmission of any CAN frame from the PLC regardless of the higher level CAN protocol and is capable of receiving a number of pre-defined CAN frames from the CAN network.

CAN 2.0A is the underlying protocol of many fieldbus protocols, CANopen being one of them. When the application disables CANopen functionality, it still retains access to this protocol.

HMS provides dedicated PLC function blocks for the transparent CAN functionality that give the designer of the PLC program the possibility to interpret and generate any CAN frame directly in the PLC program and thereby making it possible to implement customer specific protocols. Furthermore, it is also possible to connect devices that only support customer specific CAN protocols to a PROFIBUS or PROFINET network.

Functionality supported in transparent CAN mode

  • Functionality to transmit and receive CAN frames in the PLC program
  • Possibility to implement any custom CAN based protocol on the slave side, which is controlled by the PLC
  • Special PLC function blocks available for easy integration in to SIMATIC STEP 7 or TIA Portal
  • Supports for CAN 2.0A (11 bit CAN identifier) only
  • Selectable bit rate from 20 kbit/s – 1 Mbit/s
  • CANopen functionality is disabled when the transparent CAN mode is used

The 1 SI CANopen for the SIMATIC ET200®S modular I/O system and the CM CANopen module for the SIMATIC S7-1200® basic controller implement the HMS CANopen master technology in a compact format fully integrated with the SIMATIC hardware. They allow to directly extend SIMATIC automation solutions with CAN or CANopen based equipment making more expensive and space demanding PROFIBUS or PROFINET to CANopen gateways unnecessary. 

Both modules are supported by optimized and highly intuitive CANopen configuration tools that enable users to quickly generate all required configuration data for the CANopen network.
Due to the support for operation in transparent CAN 2.0A mode, system integrators have the possibility to implement any custom CAN based fieldbus protocol.
