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:
dDiagnostics status wrapper.
bufferPointer to slave process data.

Reimplemented in WG0X, WG021, EK1122, and WG014.

Definition at line 557 of file ethercat_device.cpp.

Adds diagnostic information for EtherCAT ports.

Parameters:
dEtherCAT port diagnostics information will be appended.
bufferNumber 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:
vecVector of diagnostics status messages. Slave appends one or more new diagnostic status'.
bufferPointer 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 
) [inline, virtual]
Parameters:
resetwhen asserted this will clear diagnostic error conditions device safety disable
haltwhile 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 
) [inline, virtual]

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

Parameters:
reasonMessage to put in trace as reason.
levelLevel to put in trace (aka ERROR=2, WARN=1, OK=0)
delayPublish trace after delay cyles. For 1kHz realtime loop 1cycle = 1ms.
Returns:
Return true if device support publishing trace. False, if not.

Reimplemented in WG0X.
