8.3 Setting the Trigger Edge for the Reference Pulse
The time for reference-pulse triggering can be set to the rising or falling edge or to both edges of the reference-pulse signal.
If both edges are used for the trigger event, it must be ensured that the maximum trigger rate is not exceeded.
Function
EIB7_ERR EIB7SetRITriggerEdge ( EIB7_AXIS axis,
EIB7_RITriggerEdge edge
)
Parameters
axis AXIS handle
edge Active trigger edge for the reference pulse
edge Description
EIB7_RI_Rising Rising edge of the reference pulse
EIB7_RI_Falling Falling edge of the reference pulse
EIB7_RI_Both Both edges of the reference pulse
Return code
The return code delivers a status for the function call. In addition to the standard return codes, the following error messages
