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

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.

R715       *Control PCM, PH, and Servo Hub from roboRIO. Each Pneumatic Control Module (PCM), Pneumatic Hub (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).

R711       *Don’t connect motor outputs to roboRIO. Neither 12VDC power nor relay module or motor controller outputs shall be directly connected to the roboRIO, with the exception of the designated 12VDC input.
