gregor91 Posts: 2 Rating: (0)	I would like to control some home devices using Logo!8 via ethernet. I have two applications for android which I can use (including Siemens App). Unfortunately I have some problems with this. These applications let me to set a network input or flag (not Siemens app) but I have to reset that network input via android because there's no momentary buttons. So my question is how to reset flag or network input in FBD program in LSC v8. My program works in that way: network input sets Q output for 2 seconds, after that time I’ would like to reset network input (or flag). Which FBD instruction should I use?

Zymo Posts: 6 Rating: (0)	Hello, I am having the same problem. I use the logo and additional digital outputs to control lightning at home. All of the lights are programmed using momentary switches and easy blocks like timers etc.It would be nice if you can control the lights using the Logo! app, the only thing is, those switches not momentary. I can program them to control simple outputs, like on/off but then i discovered they are not in sync with the inputs on the logo (hardware switches for example). I read about getting the network in and outputs on the same adress but i really don't get it.. when simulating this, weird thing happens like loops. What am i doing wrong? Many greetings,

In attachment a screen video. There you can see the program in online mode and place of the app I use the web server. As you can see, you can also switch multiple network inputs or pushbuttons connected to digital inputs in parallel. but it is always important, which is used during network entry, a network output with the same address.

Zymo Posts: 6 Rating: (0)	Hello Ixo65, Thank you for the video and diagram! I'll almost get it right :) Just a few questions, using the webserver, the 'modifiy' acts like a momentary switch right? The problem is, i wanted to use the logo app, which doesn't have momentary switches. If i program this with the switches and you press 'on' on the app for example, the hardware switch (digital input) doesn't know its state. The status low 0 on the diagram, whats its function for this? Again, thank you for the info but i'm very new with this. Greetings, Z

App. If a bit is set in the V-section to 1, it remains both the web server and on the Logo! App to 1 and must be specifically set back to 0. This is a static response as a switch. The constant LOW writing a network output with the same address as the network input, the bit is reset to 0. Because the whole thing needed only one cycle, you do not see the 1 state in the web server. And believe me, this also works with the Logo! App. You are not the first to have this Problem.

Zymo Posts: 6 Rating: (0)	Hi Ixo65, I tried the demo that you gave. Thank you for that, i learned alot from it. So i programed the button 1 and button 2 in the app, left button off, right button on. The value of the right button is 1 so everytime you hit it, you can switch the output Q with it, just like a momentary switch. It would be great if you can program both buttons in the app with a unique state, so left one is off, right one on. If you know what i mean. Or, it would be nice to have just one button in the app, a bit stupid that SIemens didn't put this in the app..
