Profile switching dependence on I/O event
Another profile switch method is based on I/O event. Events happen when the value of
enabled I/O intersects thresholds (enter, exit, on both, hysteresis) predefined by High and Low
level thresholds. SW21, SW22, SW23, SW24 stands for “Switch to profile No. X”. After an event
happens, FM6320 switches to a defined profile. Using profile switching you can create smart
applications. SW2X actions can be performed only if “Profile change on event” is enabled in
Global parameters. Pictures below illustrate profile switching depending on digital events:
1) H:0 L:0 Event: on exit
2) H:1 L:1 Event: on entrance
3) H:1 L:1 Event:on exit
4) H:0 L:0 Event: on entrance
