Hello dear Comunity,

I have another problem with a timeloop. I have 6 switching outputs that should be switched in a loop with adjustable time on and pause in a loop. The logic is as follows:  
Via UI setting switching time (t\_on) on for outputs (DO) and pause(t\_break) and start/stop.  
After start  
DO1 TRUE while t\_on, all DO FALSE while t\_break  
DO2 TRUE while t\_on, all DO FALSE while t\_break  
...  
DO6 TRUE while t\_on, all DO FALSE while t\_break  
DO1 TRUE while t\_on, all DO FALSE while t\_break  
....  
I don't have a clever solution yet to implement this in Node-Red - thank you!

Have you thought about using the msg.delay option within the 'delay' node?

 ![variable_delay](https://us1.discourse-cdn.com/flex026/uploads/nodered/original/3X/b/c/bc9dbbc37a2dfe606e4e2756aca5445231e21c3d.png)  
Please note the value you pass-in is the number of **milliseconds** for the delay.  
So 5000 would represent a delay of 5-secs.

Note:  
I've used this method in some of my Finite State Machines (FSMs) where I needed a transition from one state to another that had a variable time delay.
