Description
B&R EX270 (Full Model: 7EX270.50-1) CAN Bus Controller Module. Connection Port 9-pin D-sub (male) for the CAN bus line. It protects the sensitive CPU from electrical noise or power surges coming from the long CAN bus cables that run through the machine. Communication 1 CAN interface (electrically isolated). The B&R EX270 (Full Model: 7EX270.50-1 ) is a CAN Bus Controller module for the B&R System 2003 series. In your specific hardware lineup (alongside the Schaltag SCU and the CM211), this module acts as the communication gateway that allows the PLC to "talk" to other parts of the machine over a CAN network. Technical Specifications Feature Details Model Number 7EX270.50-1 Primary Function CAN bus controller / Interface module Supply Voltage 24 VDC (Operating range 18–30 VDC) Power Consumption Approx. 4–5 W Communication 1 CAN interface (electrically isolated) Network Speed Up to 500 kbaud Connection Port 9-pin D-sub (male) for the CAN bus line The "Bridge" Role While the CM211 module you asked about earlier handles the raw physical signals (inputs/outputs), the EX270 handles the data logic . Networking: It allows the System 2003 rack to connect to external devices like motor drives, encoders, or even other PLC racks. Isolation: The "electrically isolated" feature is critical in industrial environments. It protects the sensitive CPU from electrical noise or power surges coming from the long CAN bus cables that run through the machine. System Integration: In a Rieter draw frame , the EX270 is typically the module that sends commands to the servo controllers to adjust speed based on the sliver thickness data processed by the SCU. Hardware Pairing You will almost always find the EX270 and the CM211 mounted together on the same backplane. The EX270 usually requires a TB712 terminal block or a 9-pin D-sub cable for the network connection. If you are looking at a used or refurbished unit, ensure the revision (e.g., Rev. H0) matches your existing hardware, as some older Rieter machines have specific firmware requirements for these communication modules.
