Abstract
For discovering and safely transitioning transactors to a run mode, a message module determines if a message received from a communication master after a reset is a discovery message and determines if the message is an initial message received from the communication master. A command module, in response to the message not being the discovery message and the message being the initial message, activates a safety fault. In addition, the command module, in response to the message not being the discovery message and not being the initial message, determines whether the message comprises a valid safety command. In response to the message including a valid safety command, the command module enters the run mode.
