Resetting flag

Hello, I'd like to know how could I reset a flag (i.e. M1) that I set via web interface.

Say that I start a cycle via M1 (on the web page), I expect that once the cycle is started the program will reset the M1 so on the next cycle (few seconds after) I will find the M1 again to 0. I don't know how to accomplish that.

Thanks

The web interface in attachment.

If' I can't, how can I give a remote start to my program and find my start signal resetted to 0 ?

Thanks

Ok, it works as I intended.

Thanks.
