Slave Control API > BS2_GetSlaveDevice

In case of CoreStation, searches a slave device from the RS-485 network.


#include "BS_API.h"
int BS2_GetSlaveExDevice(void* context, uint32_t deviceId, uint32_t channelPort, BS2Rs485SlaveDeviceEX** slaveDevices, uint32_t* outchannelPort, uint32_t* slaveDeviceCount);


  • [In] context : Context
  • [In] deviceId : Device ID
  • [In] channelPort : Channel port
  • [Out] slaveDevices : Slave device list pointer
  • [Out] outchannelPort : Channel port of slave device
  • [Out] slaveDeviceCount : Number of slave devices

slaveDeviceObj variable needs to return the memory to the system by the BS2_ReleaseObject function after being used.

Return Value

If successfully done, BS_SDK_SUCCESS will be returned. If there is an error, the corresponding error code will be returned.
