CLick PLC Timers / Trip Delay

I'm trying to find a way to put a common say 60 second delay / timer block in line before trips are activated.

 

There are a large number of trips so I'm trying to avoid onerous code / making an individual timer for each trip, or having to use every single trip to activating a single timer etc.

 

Is there a way to drop a common delay in a rung easily?

      What Todd said. To get additional fidelity, instead of using integers for each copy, you could pack bits into a word and then depending on which bit is on indicates which alarm is active.

        I was thinking the same, but haven't done it in Click to comfortably show how.

        Thanks for the replies.

        It turned out easier than I assumed.

        I made a single timer at the start of my latched trip page. It gets reset whenever the plant reset push button is activated or when the plant is put into standby. I then dropped that timer into each rung / trip I wanted delayed. So the timer activates when the process is started, and only delays low risk trips so it can get up and running.
