Hi all I would like restart a branch iteratively. Now I set a injection with repeat function but the minimum step time is 1s. How I can restart many times as in a ladder code for example plc hardware?  
Many thanks

You can set the inject repeat frequency to less than 1s, it's not a very reliable interval though.

On a Raspberry Pi Zero 2, with repeat set to every 0.01 seconds, I get about 98 messages through a gate opened for 1s.  
Set to 0.001s I get something like 750 messages per second, and it doesn't change if I increase the frequency further.

What is it that you want to do faster than 1 second? If you are polling something then there may be a better way.
