The items in this section are not displayed when the module has no interlock conditions configured.
Reset button - This button is used to clear the first-out indicator (red arrow). The Reset button is displayed whenever one or more red arrows point to the interlock condition text descriptions.
First-out Indicator - Whenever there is a transition from no interlock conditions active to one or more interlock conditions active , a red arrow points to the text description of any new interlock condition. Typically, only one red arrow is displayed, but multiple arrows are possible when multiple conditions become active in a given module execution. The Reset button clears any visible red arrows. Note that the red arrows do not clear when the interlock conditions clear; the arrows must be cleared using the reset button. However, the first-out trap updates when necessary even when it has not been reset using the reset button.
Condition and Bypass - Up to eight text descriptions of interlock conditions can be displayed in this section, each having a bypass check box to its right. The text is gray when the condition is not active (PRE_OUT_D in the corresponding Condition block is 0). The text is dark red when the condition is active (PRE_OUT_D is 1). The bypass check box can be checked to bypass the interlock condition. When this is done, DISABLE in the Condition block is set to 1, forcing OUT_D to 0. This prevents an interlock from occurring for that condition, even though the expression might evaluate to True. A condition description in dark red indicates an interlock or the potential for an interlock only when the bypass check box is cleared. The DISABLE parameters in the Condition blocks have a restricted control writelock by default. Bypassing interlock conditions is intended for individuals with sufficient authority to do so.
