int hm_IsAttained();

參數

無

回傳值

Return the status of the homing operation. When the status value equals CIA402_HM_RUNNING, it indicates that the homing process is still in progress. The bit definitions of the status are shown in the table below.

Bit	名稱	值	描述
0	CIA402_HM_ATTAINED	0	Homing mode not yet completed.
		1	Homing mode carried out successfully.
1	CIA402_HM_ERROR	0	No homing error.
		1	Homing error occurred.

備註

This function must be called after a successful execution of EthercatMaster::start(). This function is non-blocking and can be called in callback functions.
