RtecatWriteSubDeviceEEprom

RtecatWriteSubDeviceEEprom writes a double word into a SubDevice’s EEPROM.

Syntax

Copy

RTECAT_COMMAND_STATUS RtecatWriteSubDeviceEEprom(
  [in]    RTECAT_HANDLE SubDevice,
  [in]    ULONG Offset,
  [in]    DWORD Data
);

Parameters

[in] SubDevice

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

[in] Offset

The offset in the EEPROM space.

[in] Data

A value to write into a SubDevice’s EEPROM.

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.
ecatErrWrongParameter	Parameter SubDevice is invalid.
ecatErrWrongEnvironment	The EEPROM requesting channel is occupied.
ecatErrMainDeviceNotReady	The MainDevice is not ready.

Remarks

RtecatWriteSubDeviceEEprom 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.
