Hi all, I was wondering if anybody knows how to reset a retentive timer after it has started timing. I am using Schneider Electric's EcoStruxure Machine Expert Basic software. The book I am reading in on Allen Bradley controllers and it uses an RES command to reset. Thanks for any help.

You can set it on operate block with %TMx.V :=0 command when timer input is false and not yet timed.

%TM.0.V can only writed from animation view


I think, that it is easier to code own timer with add block for %MW or %MD adress and 1s pulsing.

For M241 I used FB_Timer but I'm not sure if you have access to that library in basic version. If you do then you can reset i_xEnable and i_xRetentive at the same time; that will reset the time.

Basic version turned out to be nothing like the Pro ( is that what it's called?).

Maybe you can try this one, i have done some researches and it have done well.

%M71 = enable / disable
%M74 = reset button
%M72 = just ignore it
"20" = My constant preset
