Thanks for the response, as I've thought about this problem over the last month I began to suspect this was a problem with not being able to exactly represent .1 as a 32 bit binary number. I think I've found a work around by making the number an integer, then dividing it by 10 and storing that value as a floating point number. There is still an issue with the value not being exact somewhere in the 8th or 9th decimal place, but because I'm incrementing an integer value then dividing it, the error doesn't compound.

A got a larger project but this very small example makes it clear. I have a button, and after it's clicked a lamp should flip on and stays on, and when the mouse-button is released it should stay on. When I try that in the PLC_PRG it works, but when I change it to a function block (seet attched demo proj) it isn't. I'm fairly new to PLC programming but are very experienced C# engineer, but this goes above my head...

You could use the Modulo function to get the minute part from the total minutes: Minutes := TotalMinutes MOD 60;

Your function block instance is not called, so the code is not executed to set the light on when the button is pressed.

Only logged in to agree with the above. So counter intuitive. Why does an associated action force the variable when the step it is associated to is not active? Makes no sense at all, is terrible to debug and costs a lot of time. Such as shame.

Here a code for an Operation Counter with : days,hours,minutes,seconds as an example, maybe it points you the right direction ?

Hello, You use the WAGOUpload tool. You can download it on the download center of WAGO. Make a backup and restore it on the new device. (if can check the remanent data to copy the persistent variables if necessary) You can also use a SD card, go to the WBM copy it the image to the SD card and restart the other controller on the SD card. In the WBM, copy it back to the internal flash. If you contact your local Wago office, they will more than probably help you. There is also a WAGO forum. RP,

Hello, This is an old topic but it might help. This can/should be solved by either of the solution below 1. disabling the "Support client animations and overlay of native elements" option in the visualization Manager (which is handy) 2. disabling the "Hardware acceleration" of the browser. Saw it happening on some clients/PC and on other it works fine with the same webvisu... (Version 3.5.19.20 with visu package 4.4.0.0) Hopefully it will be fixed it in a next release. I haven't tested the 4.5.0.0 visu packages yet. RP,

To search for an exact phrase, put it in quotes. Example: "getting started docs"
To exclude a word or phrase, put a dash in front of it. Example: docs -help
To search on specific fields, use these field names instead of a general text search. You can group with AND or OR.
