RtecatWriteSubDeviceAlias

RtecatWriteSubDeviceAlias writes an alias address into a SubDevice.

Syntax

Copy

RTECAT_COMMAND_STATUS RtecatWriteSubDeviceAlias(
  [in]    RTECAT_HANDLE SubDevice,
  [in]    WORD Alias
);

Parameters

[in] SubDevice

A handle to a SubDevice. To retrieve the corresponding handle, use RtecatOpenSubDeviceByIndex, RtecatOpenSubDeviceByStationAddress, or RtecatOpenSubDeviceByExplicitId.

[in] Alias

An alias address to write into a SubDevice.

Return Values

The function returns an RTECAT_COMMAND_STATUS structure. If an error occurs, field State of the structure is set to ecatCommandError and the error code is stored in field ErrorId (see RTECAT_ERROR for error values). If the function succeeds, ErrorId is set to ecatErrNoError (which is represented by the value 0). If the function fails, it stores a different error value.

Possible return values:

Return value	Meaning
ecatErrNoError	The function succeeded.
ecatErrNullParameter	Parameter Alias is NULL.
ecatErrWrongParameter	Parameter SubDevice is invalid.
ecatErrMainDeviceNotReady	The MainDevice is not ready.

Remarks

RtecatWriteSubDeviceAlias is an asynchronous function that takes time to complete. It allows for background execution and requires you to check its status by calling RtecatGetCommandStatus or wait for it to complete by calling RtecatWaitForCommand.
