I can see the data in my LOGO (checked with the I/O-status) just fine, but my data is not updating on the web interface. Can any of you help me to figure out what i'm missing please? Both my LOGO-program and LWE-project should be in the attachement. Thanks for the help Regards Arie Attachment Gasdetection TryOut.zip (372 Downloads)

Since I don't have your Modbus device, I deleted the Modbus connection to be able to simulate values. And I can see the result (AM1 to AM4) of the simulated values in the extended web server without any problems.

BM I use is a 12/24RCEo (0BA1 version). I've added the logfile of the I/O-status and that shows a value for AM2, but the webserver still shows nothing (see screenshot). Any ideas what might be wrong?

Value of B002 (AM5 ) multiplied with the value of B003 (AM6) and then dividied with 1000. The Log file shows: AM5 = 0, AM6 = 50. So 0 * 50 / 1000 = 0. AM1 shows in the Log file 0. See your calculation for AM2. Value of B018 (AM7 ) multiplied with the value of B019 (AM8) and then dividied with 1000. The Log file shows: AM5 = 548, AM6 = 10. So 548 * 10 / 1000 = 5,48, the LOGO! rounds down to 5. AM2 shows in the Log file 5. See your calculation for AM3. Value of B034 (AM9 ) multiplied with the value of B035 (AM10) and then dividied with 1000. The Log file shows: AM5 = 0, AM6 = 100. So 0 * 100 / 1000 = 0. AM3 shows in the Log file 0. See your calculation for AM4. Value of B050 (AM11 ) multiplied with the value of B051 (AM12) and then dividied with 1000. The Log file shows: AM5 = 0, AM6 = 1000. So 0 * 1000 / 1000 = 0. AM4 shows in the Log file 0.
