R716       *Don’t alter the CAN bus. No device that interferes with, alters, or blocks communications among the roboRIO and the PDP/PDH, PCMs/PHs, and/or CAN motor controllers on the bus will be permitted.

R715       *Control PCM, PH, and Servo Hub from roboRIO. Each PCM, PH, and Servo Hub must be controlled with signal inputs sourced from the roboRIO and passed via a CAN bus connection from the built-in CAN on the roboRIO (either directly or daisy-chained via another CAN bus device).

R717       *USB to CAN adapter permitted. Additional CAN bus connections may be added to the roboRIO using the CTR Electronics CANivoreTM (P/N 21-678682, WCP-1522) USB-to-CAN adapter.

R712       *Control PWM controllers from the roboRIO. Every relay module (per R504-B), servo, Servo Power Module, and PWM motor controller shall be connected to a corresponding port (relays to Relay ports, servos, and PWM controllers to PWM ports) on the roboRIO (either directly or through a WCP Spartan Sensor Board) or via a legal MXP connection (per R713). They shall not be controlled by signals from any other source, with the exception of the Nidec Dynamo motor controller which must also be connected to the roboRIO Digital I/O.
