4.24 Trigger subsystem
The Trigger subsystem is made up of a series of commands and subsystems to configure the
three layers of the Trigger Model (see Figure 4-13). These commands and subsystems are sum-
marized in Table 4-32.

Enable (1 or ON) or disable (0 or OFF) continuous initiation of trigger sys-
tem.
Query continuous initiation.
Reset trigger system.
Subsystem command path to configure arm layers:
Path to program arm layer 1:
Loop around control source.

Query arm count.
Select control source: HOLD, IMMediate, MANual, BUS, TLINk, EXTer-
nal.
Query control source.
Loop around control source.
Path to configure Triggers:
Enable (SOUR) or disable (ACC) Bypass: SOURce, ACCeptor.
Query direction.
Path to configure asynchronous Trigger Link:
Select input line (1 to 6).

Select output line (1 to 6).
Query output line.
Path to program arm layer 2:
Loop around control source.
Program scan count (1 to 99999 or INF).
Query scan count.
Program delay (0 to 999999.999 sec)
Query delay.
Select control source: HOLD, IMMediate, TIMer, MANual, BUS, TLINk,
EXTernal.
Query control source.
Set timer interval (0.001 to 999999.999 sec)
Query timer.
Loop around control source.
Path to configure Triggers:
