bool EthercatHardware::publishTrace	(	int	position,
		const string &	reason,
		unsigned	level,
		unsigned	delay
	)

Ask one or all EtherCAT devices to publish (motor) traces.

Parameters:

position	device ring position to publish trace for. Use -1 to trigger all devices.
reason	Message to put in trace as reason.
level	Level to put in trace (aka ERROR=2, WARN=1, OK=0)
delay	Publish trace after delay cyles. For 1kHz realtime loop 1cycle = 1ms.

Returns:: Return true if device supports publishing trace. False, if not. If all devices are triggered, returns true if any device publishes trace.

void EthercatHardware::update	(	bool	reset,
		bool	halt
	)

Send most recent motor commands and retrieve updates. This command must be run at a sufficient rate or else the motors will be disabled.

Parameters:

reset	A boolean indicating if the motor controller boards should be reset
halt	A boolean indicating if the motors should be halted
