 Good afternoon Nguyen, what do you mean exactly by you see it at program mode? do you mean instead of the normal home screen you go straight to the menu screen?

 Is it continue in program mode when ever you power off and on?

 what you mean logo should stop program after  power off happen ?

my point of view when I turn off my logo power after when I turn on then its program running mode if before power off running mode other condition if your logo stop mode before power off and when you turn on its power it will stop mode .

which condition with your logo ?

hope this will helpful.

A Logo that is in RUN when power goes down stops.

When power is Coming back then:

If there is a memorymodule in the LOGO, the progtramm on the memorymodule is copierd into the LOGO, and after that the LOGO starts running with the programm and settings of the contens of the memorymodule.

If there is NO memorycard in the LOGO, the LOGO starts running.

You can never lost the programm when power goes down.

If the power is down for a long time (for timen See manual) the Clock wil not by on the right time!

All the settings in the LOGO blockt that have RETENTIVITY ON have the value as just before the power down. Blocks with RETENTIVITY OFF starts with the original initial value.

The value of the "Hours Counter" OT wil always retentivity.

The Marker M8 ( LOGO >0BA4) wil give 1 puls (Initial) when power is going on, only the first cyclus of the programm.

The programm in the LOGO is in a FLASH-Memory and wil never lost, until you deleted it manualy, It stay for more then 10.000 years there!

If I understand the topics starter correctly, the logo should have gone not automatically go to RUN mode after return of voltage, but went into the programming mode.

This error is not known to me.

If no program in the logo, it would remain in STOP and could no longer be started. The case so it can not have been.

Hi all,

I dont know exactly.  we start production again after few days stopping, suddently the logo dont make output. My colleague checked condition but nothing change.

That morning I connected to it by my PC and upload program. That afternoon I come back and saw it in stop like attracted file.

After that I make it to run by software and it work propely.

logo will high output when your program conditions met with logic check your logo logic inputs, outputs, timers etc.

you can troubleshoot with diagnose  with online mode .

it will helpful.

if this not helpful describe more about your problem with help of err picture etc.

The picture is not complete. So is it not helpful.

 This picture is cut from manual but it the same actual. Because in case that, Logo is in operator user.

  How long have you been manualy stopping and starting the LOGO for?

 Only that time. I will check next times what happend.

No, because it does not show a complete picture. You can not see what would be seen in the upper section.

Or you want to ensure that only announce that the logo on failure shows the first entry of system menu? Then you need no picture.

I know of no error where the logo with a program during program execution (RUN) is turned off, then not again automatically goes into RUN, but starts with the system menu.

 Thats the normal screen when you power on your LOGO and as kormotech staited it should be in run mode, Make sure if its not running that you dont have a ``reset button´´ anywhere

If have told you before:

First: Your LOGO must have a working programm

(it can be easy  I1 == Q1)

Then sitch LOGO to RUN

You get (if you dot use Textblocks in your programm) the date and time on your display.

If you turn power OFF and than switch power on then LOGO goes automaticaly in RUN mode

The time between OFF and On could be seconds, but also more then 100 Years, every time it wil be the same.

LOGO starts in RUN

But when LOGO is NOT in RUN when power is gowing off, then LOGO wil NOT starting in RUN automaticaly with a working programm.

 Did you checked your logic inputs ?

 because output hi depend your logic involved inputs condition whether these hi or low. you should know you logic operation how it works.

 You can easyly check inputs outputs and so on on LOGO. When the date and time is in the display, and LOGO is in RUN status, you can press the left or right cursor key. Then you get the real information of inputs, next press OUtputs, Analog in and outputs and internal Marker. Its helpful if you think your LOGO is not working well, you see the inputs and make your conclusions.

Has your problem been solved Nguyen?

 Thanks. This problem happened only one time for now.
