Posted 14 Jan 2005 Hi, i am new with step 7 programming and i have few question if somebody could help me first i made a little program with OB1 and a FC i try the online mode to see the state of bits but i can't see OB1 and FC1 at the same time online one can be online at once? is there a solution fo that? tkank you Share this post Link to post Share on other sites
Posted 14 Jan 2005 To see the values of OB1 and your FC you have to create a variable table. From the menu Insert ,S7 Block , Variable table , the default first variable table is VAT_1 from there you can insert the addresses you wish to monitor.

Posted 14 Jan 2005 thank you for your answer i ever did that but it would be cool to visualise the state of each net... Share this post Link to post Share on other sites
Posted 17 Jan 2005 you can actually look at both blocks simultaneously by opening both OB1 and your FC within the ladder editor. Then go to <window><arrange><horizontally> and click on the "eye glasses" icon for each window and you will see both of them animating at the same time.

Posted 17 Jan 2005 I think it might be a CPU limitation, especially if you are using a 3xx CPU. I notice that when I'm checking out a program online and change from one FB/FC/OB to another, I get a message box telling me that the observation of the first window will be shut down (even though it's not on screen at the time). I suspect it may also have something to do with how long each program is, because I'm 99% certain that on a relatively small machine I did a few months back, I was able to observe two different FCs or one FC and OB1 at the same time. My current project is much more complex. Share this post Link to post Share on other sites
