Post by stribor on Passing properties as VAR_IN_OUT variables. ^{CODESYS Forge talk (Post)}
if i only use it as input variable I won't be able to update its state within the visu object. Lets say i have real value as a property, i would like the slider object to display this value and also modify it.

You can write any expression that evaluates to TRUE/FALSE in that property, you can also call a method from the property.

Put %f in the "text" field and rValue in the "Text variable" field. You could also have a look at the possible placeholders: https://content.helpme-codesys.com/en/CODESYS%20Visualization/_visu_placeholder_with_formatting_sequence_in_a_string.html

Post by dogulas on numeric text box control ^{CODESYS Forge talk (Post)}
I am using TargetVisu in my v3.5 sp20 p6 (64-bit) project. I see no control that will allow me to bind, edit, and display a LREAL variable. Am I missing a library? If it exists, why can't I see it?

Post by snhatton on Visu - changing auto-logout time ^{CODESYS Forge talk (Post)}
You could try using the VUM_UserGroup struct from the VisuUserManagement library. I haven't tried this, but there is a variable for tAutoLogout to set the logout time.

Post by ton on How to create a stopwatch? ^{CODESYS Forge talk (Post)}
Hi, i guess you want to make a hour counter. You need to store the measured value. Try to use a retain variable, but need a graceful shutdown, or save it your self. see https://forge.codesys.com/forge/talk/Runtime/thread/278e325579/ Succes.

Could not find the solution to this issue but I have side stepped this by creating a global variable MAX_SIZE.

Is there a way to move the slave axis across the zero point of the master axis with variable start and stop points? For example: Slave start at 270° and end at 50°. thanks :)

if you just want to show the currently logged in user in the visualization, then just create a field with text %s and as text variable VisuElems.CurrentUserName

Post by matt-s on HMI Pushbutton/Move Instruction ^{CODESYS Forge talk (Post)}
I know, that is not the issue though. The issue is the HMI_Blower_Auto_PB variable not changing to false. I do not have the IO modules plugged in yet, that is why there are NaN values for those variables. That should not affect this.

Post by masmith1553 on HMI Pushbutton/Move Instruction ^{CODESYS Forge talk (Post)}
Have you cross referenced the variable to see if it is being written some where else? You could try an Execute block instead of a Move.

Hey mate, did you get to the bottom of this? If not, have you double checked the buttons are linked to the correct variables and/or performing the correct action? Have you tried always enabling the block to confirm false is moved to the variable if so?

with every call of the FB500 it keeps adding the INTs of the array to the sum variable. set sum to 0 before you start the loop.

Post by tvm on Timer On Vijeo ^{CODESYS Forge talk (Post)}
Vijeo doesn't support TIME variables, so the easiest thing to do is convert to a STRING in your program, and use that variable. You could use TimeAsString:= TIME_TO_STRING(TimeVar) to get a string that looks like this: T#5h10m45s200ms

Post by hwopereis on SFC Action problems ^{CODESYS Forge talk (Post)}
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.
