Post by pistola on Case Function - Multiple Conditions, Is it possible? ^{CODESYS Forge talk (Post)}
Thanks for the information, I ended up just making a long if else statement as each variable had 3 possible options, I figured at least this way it would still work.

thank you, i tried your library and device description but i don't get analog values. Do i something wrong? i also got an library error at the I2C_BASE functionblock the calcCycleTime gave an variable size error, so i added thet conversion from ULINT_TO_UDINT.

That works, thanks, I was trying to get a variable into the Position>Height and was struggling, then I was using absolute movement, never though to try relative movement.

Post by tvm on Passing properties as VAR_IN_OUT variables. ^{CODESYS Forge talk (Post)}
Use a VAR_INPUT for properties. The reason for the error is that you can't get a reference to a property. Using a VAR_INPUT will copy the property to an input variable.

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.

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.

I need to connect 2 computers on the same network that are running codesys, so that they can receive and change variable values from each other. This connection must preferably be made using Modbus.

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 sigurdrb on Read codesys version in the codesys application ^{CODESYS Forge talk (Post)}
Hi! I want to read the codesys version into the project, so I can highlight it in the SCADA system. VAR dwVersion : DWORD; END_VAR SysTarget.SysTargetGetVersion(pulVersion := ADR(dwVersion)); This gives me the value 100859909. I tried to search ths up and found som older post (https://forge.codesys.com/forge/talk/Runtime/thread/a55981ff4d/) that said each 4 bytes reads a number in the version. Example is 50662666 = 16#03050D0A which reads to V3.5.13.10 When I run this code I get the value 100859909, which I cant translate to anything meaningful. I am running it on Codesys V3.5.19.70. Help appreciated!
