CM202

The proven Controller Area Network, based on a 2-wire connection, is optimized for maximum communication robustness. It is continuously applied in existing and new applications.

Several CAN-based protocols are available as software solutions and can be chosen by configuration:

• CANopen is configured in SolutionCenter by means of EDS files of the devices, and delivers process data directly into the process image
• J1939 and NMEA 2000 are supported by the software module J1939SRV
• Further, also proprietary protocols may be implemented by application programs

The two CAN connections on the module may be used independent of each other to operate two completely separated networks. Both connections are galvanically isolated from the controller and short-circuit-proof.

Configuration options for each connection:

• NMT MainDevice according to CANopen
• NMT SubDevice according to CANopen
• Further CAN protocols

Alternatively, both connections may be electrically connected by DIP switches, to enable a daisy-chain cabling from station to station.

• Up to 4 CM202 modules per M200 controller
• Up to 8 CAN networks per controller
• Operation mode is selected independently for each network
• Node Guarding or Heartbeat protocol for network monitoring
• Easy configuration
• Monitors for commissioning and diagnosis in SolutionCenter
• Extensive API for SDO, LMT, LSS, Emergency messages
• Maximum cable length depending on baud rate
• Maximum number of network nodes depending on baud rate
• Transfer rate 10 Kbaud to 1 Mbaud
• Galvanically isolated
• Short-circuit-proof
