Event triggering
You can use Event-triggered commands 1 – 4 to execute the specified PR path. You can select
two types of Event triggering: rising-edge trigger and falling-edge trigger. The range of PR path
numbers that you can specify is from 51 – 63 (see example in Figure 7.1.5.3). Before using the
Event-trigger for PR command, you must define the DI functions, which are [0x39] Event-trigger
command 1, [0x3A] Event-trigger command 2, [0x3B] Event-trigger command 3, and [0x3C]
Event-trigger command 4 (see Table 8.1). You can use ASDA-Soft to set the I/O triggering as
shown in Figure 7.1.5.4.
