ControlSafe™ IOU-CAN ModuleControlSafe™ Platform Module
The SMART Embedded Computing IOU-CAN module extends the capability of the ControlSafe™ Computer Platform to interface with up to four High Speed Controller Area Network busses (HSCAN). With rear RTM access I/O it is perfect for wayside applications requiring CAN connectivity to devices or external I/O boxes, for use in applications such as Computer Based Interlocking (CBI), Automatic Train Protection (ATP), Automatic Train Operation (ATO), and Positive Train Control (PTC).
This module packetizes and transmits all incoming CAN traffic (using the Ethernet fabric) to the application on the CPU module. Similarly, the CPU module will packetize and transmit any outgoing CAN frames to the cIOU-CAN module for transmission over the CANbus. This module also supports a port mirroring function, which allows both Active and Standby CPUs to access CAN traffic simultaneously.
