Function Documentation

boolean ecx_configdc

(

ecx_contextt *

context

)

Locate DC slaves, measure propagation delays.

Parameters

[in]

context

= context struct

Returns

boolean if slaves are found with DC

Definition at line 270 of file ethercatdc.c.

void ecx_dcsync0	(	ecx_contextt *	context,
		uint16	slave,
		boolean	act,
		uint32	CyclTime,
		uint32	CyclShift
	)

Set DC of slave to fire sync0 at CyclTime interval with CyclShift offset.

Parameters

[in]	context	= context struct
[in]	slave	Slave number.
[in]	act	TRUE = active, FALSE = deactivated
[in]	CyclTime	Cycltime in ns.
[in]	CyclShift	CyclShift in ns.

Definition at line 70 of file ethercatdc.c.

void ecx_dcsync01	(	ecx_contextt *	context,
		uint16	slave,
		boolean	act,
		uint32	CyclTime0,
		uint32	CyclTime1,
		uint32	CyclShift
	)

Set DC of slave to fire sync0 and sync1 at CyclTime interval with CyclShift offset.

Parameters

[in]	context	= context struct
[in]	slave	Slave number.
[in]	act	TRUE = active, FALSE = deactivated
[in]	CyclTime0	Cycltime SYNC0 in ns.
[in]	CyclTime1	Cycltime SYNC1 in ns. This time is a delta time in relation to the SYNC0 fire. If CylcTime1 = 0 then SYNC1 fires a the same time as SYNC0.
[in]	CyclShift	CyclShift in ns.
