Definition at line 1910 of file ethercatmain.c.

int ecx_send_overlap_processdata ( ecx_contextt *  context)

Definition at line 1993 of file ethercatmain.c.

int ecx_send_overlap_processdata_group ( ecx_contextt *  context,
uint8  group 
)

Transmit processdata to slaves. Uses LRW, or LRD/LWR if LRW is not allowed (blockLRW). Both the input and output processdata are transmitted in the overlapped IOmap. The outputs with the actual data, the inputs replace the output data in the returning frame. The inputs are gathered with the receive processdata function. In contrast to the base LRW function this function is non-blocking. If the processdata does not fit in one datagram, multiple are used. In order to recombine the slave response, a stack is used.

Parameters
[in]context= context struct
[in]group= group number
Returns
>0 if processdata is transmitted.

Definition at line 1879 of file ethercatmain.c.

int ecx_send_processdata ( ecx_contextt *  context)

Definition at line 1988 of file ethercatmain.c.

int ecx_send_processdata_group ( ecx_contextt *  context,
uint8  group 
)

Transmit processdata to slaves. Uses LRW, or LRD/LWR if LRW is not allowed (blockLRW). Both the input and output processdata are transmitted. The outputs with the actual data, the inputs have a placeholder. The inputs are gathered with the receive processdata function. In contrast to the base LRW function this function is non-blocking. If the processdata does not fit in one datagram, multiple are used. In order to recombine the slave response, a stack is used.

Parameters
[in]context= context struct
[in]group= group number
Returns
>0 if processdata is transmitted.

Definition at line 1896 of file ethercatmain.c.
