Synchronous acceptor trigger mode (SynchronousA)
Use the synchronous acceptor trigger mode (SynchronousA) on a trigger subordinate that operates
with a trigger master configured for the SynchronousM trigger mode. The roles of the internal and
external drives are reversed in the SynchronousA trigger mode.
Input characteristics:
•
The falling edge is detected as the external drive pulses the line low, and the internal drive
latches the line low.
Output characteristics:
•
In addition to trigger events from other trigger objects, the digio.trigger[N].assert() and
tsplink.trigger[N].assert() functions release the line if the line is latched low. The pulse
width is not used.
•
The physical line state does not change until all drives (internal and external) release the line.
•
Action overruns occur if the internal drive is not latched low and a source event is received.
