Multiple outputs one timer?

[Jhav]

Hello,

I was wondering if there is a simple way of using one timer for  multiple inputs.  I have multiple valves and each one has a open input and a closed input . I’m allowing  a couple seconds between status change of open and close if it does not reach the right position the valve will alarm. Is there a simple way of using one timer for all inputs instead of giving each individual input a timer?

It is tedious, but the generally accepted way is to assign one timer per valve.

If you don't use multiple timers you won't know which one failed.

This is another way - try to configure standard Alarms with configured delay. You do not specify PLC model but 16 to 128 Alarms can be configured with different delay.
