@@TohidAlizadeh no problem, can I use Codesys to program Schneider electric M171?

[@TohidAlizadeh]

@@mikefreedom5612 I am not sure if it supports CODEYSYS. I know that there is EcoStruxure Machine Expert - HVAC for programming this PLC.

IF WE OFF A LS1 AFTER 7 SECOND AND WE START LS1 AGAIN, SO A CYCLE IS START FROM "0" SECOND OR "7" SECOND???

[@TohidAlizadeh]

The counter counts the seconds provided by the Timers, and this happens when LS1 is closed. If LS! is open, the counting stops, but the counter is not reset. The counter will keep its current value until the Reset pushbutton is pressed.
I hope I have answered your question.
