The CAN 300 pro module of Systeme Helmholz GmbH for use in an S7-300¹⁾ from Siemens permits connection of CAN stations with the programmable controller.
The module can be slotted either in the central controller or in the expansion unit.

The CAN 300 pro module supports 11-bit and 29-bit CAN-IDs with a freely selectable bit-rate of 10 kbit/s to 1 Mbit/s.
The CAN 300 pro module can send and receive CAN frames in ISO/OSI layer 2 operating mode. The data of CANopen slaves can be processed as a process image in CANopen NMT master operating mode in the PLC. Applications as a CANopen NMT slave are also possible. Application examples are provided for standard applications including motor control with CANopen. Data handling blocks for the SAE J1939 protocol are also available.

The CAN 300 pro module contains 16 freely settable timers. Each timer can trigger a freely programmable CAN telegram. That way, it is easy to implement the synchronous protocols in common use in drive and servo systems using the CAN 300 pro module.

The DIP-switch for setting the bit-rate and the station address (node-ID) facilitate commissioning. An optional micro memory card stores the project so that the parameterization or the module is quickly replaced during servicing.
Six LEDs indicate the operating status of the module. An USB interface is available.

Features

• ISO/OSI layer 2, 11-bit and 29-bit CAN-IDs
• CANopen master on the module
• DIP-switch for node-ID and bit-rate
