How Keypad Commands WorkHow Keypad Commands WorkEvents activated by keypad commands are similar to latched events, because,once activated, a separate action is required to override (deactivate) it.The following sections describe the methods you can use to activate anddeactivate keypad commands.Method 1Figure 13-2 on page 13-4 demonstrates using two keypad commands tocontrol an output. Keypad command 1 and event 1 are used to activate theoutput and keypad command 2 and event 2 are used to deactivate it. Whenthe event 2 action asserts, it overrides the action of event 1, and event 1disappears.This method works well in situations when there are no other controls on theoutput. However, this method leaves a deactivation on the output atwhatever priority level is set by event 2. If keypad command 1 asserts again itwill override event 2.Figure 13-2: Method 1 - Controlling an output with two keypad commands13–4 C•CURE 800/8000 Software Configuration Guide
