StamatisJE Posts: 5 Rating: (0)	Hi experts, I have a problem modifying a REAL number from my web page. I can only modify it as an integer, but I cannot edit a decimal value. My Data Block is the DB100 where I have the settings, and my variable is the "Set Point Temperature" which is a REAL value. If I replace my "real value" with an "INT value", the web page is working, but of course only with integers. You can see my code below. Something that could be useful for you is that when I edit negative value from my web page, the result in the output field is: 4.294967e+09 An important info is that: When I use the same page for CPU1214 V3.0 it works, but when I use CPU1215 V4.0 or V4.1 it doesn't. So, what should I do to be able to edit decimal or negative values from my web page? <tr> <p> <td>Temperature set point:</td> <td class="output_field">:="100 Settings"."Set Point Temperature":</td> <!-- AWP_In_Variable Name='"100 Settings".Set Point Temperature' --> <td> <p> <form method="post"> <input name='"100 Settings".Set Point Temperature' type="text" size="1" /> <button type="submit">Confirm</button> </form> </p> </td> </p> </tr> FYI: In the head section, I use the following code. <head> <meta http-equiv="Content-Type" content="text/html; charset=utf-8"/> <meta http-equiv="Content-Script-Type" content="text/javascript"/> <!-- <meta http-equiv="refresh"content="1; URL=Seetings.html">--> <link rel="stylesheet" type="text/css" href="Stylesheet/siemens_Stylesheet.css"/> <script src="Script/siemens_script.js" type="text/javascript"></script> </head> If you want more details about my program or my web pages, please let me know. Thank you in advance. ------------------------------------------------------------------------------------------ Split from TIPs and Samples Programs for User-defined web pages and S7-1200.

When I send a Real number with decimals my variable does not change but, if I set any positive number, without point, it changes on the PLC. I also did the test with negative numbers and also got a BIG number (the one you mentioned). I was having problems with some integers also when I use negative numbers. That was because the WEB page sent me 32 bit instead of 16 (as an Integer is),then I changed the data type as DINT on the PLC and it worked fine but with real I tried to use LReal and do not work. Any suggestions? Regards PLC CPU 1214C AC/DC/Rly FW V4.1 TIA Portal V13 SP1 Upd 8 (Mozila works fine, IE is a virus)

MedinaJ Posts: 4 Rating: (0)	I was thinking the same, the problem is my poor skills in html . But, if I have to do it by multipling or using it as text and then convert it on the PLC I´m gonna do it.. I just would like to do it the right way . It is a shame that something that showld be as easy as transfer a number need too much work. Regards

But it seems that something is preventing the transmission of real numbers. So, heh, the workaround appears as the only solution
