EnableHotConnect

Allows new hardware to be added while the EtherCAT network is running.

Syntax

KsError EnableHotConnect(
     BOOL Active
);

Parameters

Active: TRUE to enable, and FALSE to disable Hot Connect. By default, it is FALSE.

Return value

If the function succeeds, it returns errNoError, otherwise an error code. For more information about the error code, see the KsError list.

Remarks

• This function must be called after Create and before Start.
• This feature requires Hot Connect Package.

Usable EtherCAT states

ecatOffline

Example

BOOL StartKingstar() {
   //Launch or connect to the KINGSTAR Subsystem process
   KsError nRet = errNoError;
   nRet = Create(INSTANCE, 0);

   SubsystemStatus Subsystem = { ecatOffline, ecatOffline, 0, 0, 0, 
	{ecatOffline}, {ecatOffline}, {axisOffline} };
   GetStatus(&Subsystem, NULL);
   if (Subsystem.State == ecatOP) {
      RtPrintf("Subsystem already started: %x\n", nRet);
      return TRUE;
   }
   else if (Subsystem.State != ecatOffline) {
      RtPrintf("Subsystem in unexpected state: %d\n", Subsystem.State);
      return FALSE;
   }

   //Configure the Subsystem settings
   nRet = SetCycleTime(cycle500);
   nRet = SetAxisAccessMode(accessPos);
   nRet = EnableServerLog(FALSE);
   nRet = EnableAxisInput(TRUE);
   nRet = EnableAxisOutput(FALSE);
   nRet = EnableSecondEncoder(FALSE);
   nRet = EnableActualVelocity(TRUE);
   nRet = EnableActualTorque(TRUE);
   nRet = EnableActualCurrent(TRUE);
   nRet = EnableFollowingError(TRUE);
   nRet = EnableMaxTorque(TRUE);
   nRet = EnableMaxCurrent(TRUE);
   nRet = EnableTorqueOffset(FALSE);
   nRet = EnableProfilePosition(FALSE);
   nRet = EnableSynchronizedControlMode(TRUE);
   nRet = EnableAutoRestart(TRUE);
   nRet = EnableAutoRepair(TRUE);
   nRet = EnableAutoConfig(TRUE);
   nRet = ConfigureDc(TRUE, TRUE, FALSE, 0);
   nRet = EnableHotConnect(TRUE);
   nRet = EnableRedundancy(TRUE);
   nRet = SetConfiguredAxesCount(1);
   nRet = SetConfiguredIoCount(3);
   SlaveStatus simulatedIo = { 0 };
   simulatedIo.InputLength = 16;
   simulatedIo.OutputLength = 16;
   for (int i = 0; i < IO_COUNT; i++) {
      nRet = ConfigureIo(i, simulatedIo);
   }

   SlaveStatus axisDefinition = { "Simulated Axis", 0 };
   ConfigureAxis(0, axisDefinition, 131072);

   //Start the EtherCAT network
   //This function is asynchronous so the network is not started yet when it returns
   KsCommandStatus status = WaitForCommand(30, TRUE, Start());

   return TRUE;
}
