When using the API of EtherCAT_Dll, the API function will return a value that shows the
execution result. Please refer to the following table for the description of those values. For
example, if the API function returns 0, it means the API is successfully executed. On the other
hand, a non-zero value is regarded as an error code. It means an error has occurred during
operation or hardware connection. Please troubleshoot the problem according to the description
