5.2 _ECAT_Master_Get_CycleTime

Syntax
U16 PASCAL _ECAT_Master_Get_CycleTime (U16 CardNo, U16 *CycleTime)

Purpose
This is for acquiring the cycle time of the
EtherCAT master communication.
Note: This function can be used only after the EtherCAT Master is enabled by “_ECAT_Master_Open” (refer
to section 6.1).

Parameter
Name Data type Property Description
CardNo U16 Number Card No.
CycleTime U16* Time (us)
Communication cycle time (unit: us);
The Master currently only supports cycle times of
2000, 1000, 500, 250, 125. For the slave cycle time,
please refer to the description of each Slave.

Example
U16 Status;
U16 CardNo=0;
U16 Cardnum=0;
U16 CycleTime =0;
Status = _ECAT_Master_Open (&Cardnum);
if (Cardnum>0)
{
Status = _ECAT_Master_Get_CardSeq (0, &CardNo);
// Acquire the Master’s CycleTime setting information.
Status = _ECAT_Master_Get_CycleTime (CardNo, &CycleTime);
}
