void EthercatDevice::collectDiagnostics ( EthercatCom * com )

virtual

Reimplemented in WG0X.

Definition at line 369 of file ethercat_device.cpp.

void EthercatDevice::construct	(	EtherCAT_SlaveHandler *	sh,
		int &	start_address
	)

virtual

< Construct EtherCAT device

Construct non-EtherCAT device

Reimplemented in WG0X, WG06, WG021, WG05, EK1122, and WG014.

Definition at line 331 of file ethercat_device.cpp.

void EthercatDevice::construct ( ros::NodeHandle & nh )

virtual

Definition at line 336 of file ethercat_device.cpp.

void EthercatDevice::diagnostics	(	diagnostic_updater::DiagnosticStatusWrapper &	d,
		unsigned char *	buffer
	)

virtual

For EtherCAT device that only publish one EtherCAT Status message. If sub-class implements multiDiagnostics() then diagnostics() is not used.

Parameters

d	Diagnostics status wrapper.
buffer	Pointer to slave process data.

Reimplemented in WG0X, WG021, EK1122, and WG014.

Definition at line 557 of file ethercat_device.cpp.

void EthercatDevice::ethercatDiagnostics	(	diagnostic_updater::DiagnosticStatusWrapper &	d,
		unsigned	numPorts
	)

Adds diagnostic information for EtherCAT ports.

Parameters

d	EtherCAT port diagnostics information will be appended.
buffer	Number of communication ports slave has.

Definition at line 538 of file ethercat_device.cpp.

virtual int EthercatDevice::initialize	(	pr2_hardware_interface::HardwareInterface *	,
		bool	allow_unprogrammed = `0`
	)

pure virtual

Implemented in WG0X, WG06, WG021, WG05, EK1122, and WG014.

void EthercatDevice::multiDiagnostics	(	vector< diagnostic_msgs::DiagnosticStatus > &	vec,
		unsigned char *	buffer
	)

virtual

For EtherCAT devices that publish more than one EtherCAT Status message. If sub-class implements multiDiagnostics() then diagnostics() is not used.

Parameters

vec	Vector of diagnostics status messages. Slave appends one or more new diagnostic status'.
buffer	Pointer to slave process data.

Reimplemented in WG06.

Definition at line 578 of file ethercat_device.cpp.

virtual void EthercatDevice::packCommand	(	unsigned char *	buffer,
		bool	halt,
		bool	reset
	)

inlinevirtual

Parameters

reset	when asserted this will clear diagnostic error conditions device safety disable
halt	while asserted will disable actuator, usually by disabling H-bridge

Reimplemented in WG0X, WG06, WG021, and WG05.

Definition at line 151 of file ethercat_device.h.

virtual bool EthercatDevice::publishTrace	(	const string &	reason,
		unsigned	level,
		unsigned	delay
	)

inlinevirtual

Asks device to publish (motor) trace. Only works for devices that support it.

Parameters

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 support publishing trace. False, if not.

Reimplemented in WG0X.
