Codesys Visualization - Text Field multiple variables?

[theColonel26]

Is there any way to bind more than one variable to a Text field?

I want to be able to doing something like this
<Value> <Unit>


104.6 F
or
56.14 PSI

etc.


Then further, to be able to specify the the format of the Value (decimal places etc)

I assume no?

Is the only way to do this to concat a string in a PRG?

What I have done in the past is a selectable text field for the type of Units using a bit i.e. Deg. C or Deg. F then the value is set to 2 decimal places (some platforms can use another field for decimal places but not all) then use the units toggle bit to move the two values into the field so for example:
AND My toggle bit move Var Deg_C to HMI_Field
AND NOT Toggle bit move Var Deg_F to HMI_Field
The units is just a fixed field that displays one of two texts depending on the toggle bit.
On Beijers HMI's I have also used a text field with multiple text lists & the variable that selects them is a integer so depending on the value of the variable it displays the text i.e.
0 Message 1
1 Message 2
3 Message 3
& so on.

I know it only half answers your question, but you can do something like. The below picture. Maybe you want to create your own Function PrettyUnitFormatter(Value:LREAL,Unit:STRING,ValueFormat:STRING)

Oh sweet !!! I didn't know I could call a function in there


I tried to bind it to a FB.property but it threw an error saying I couldn't call ADR on the assigned variable.

I will try a function.

Works you win the internet




HOWEVER is a String formatting function for REALs built in to codesys?

or am I going to have to build something to specify 0 padding and decimal padding?

You can use formatting masks like you use in the printf() function in C.

There is the printf and StuSprintf function in this library.

[theColonel26]

Where can I download that library though?

 

[AustralIan]

It should be installed in your system already. Double click library manager, Click add library, press the button on the far right labelled 'Display advanced libraries', type the function name into the search box, wait impatiently for 10 seconds, then select one of the entries for Library "StringUtils"

Sweet I found it

Clicking the advanced button is what i was missing I think.

Since you know a lot about Codesys do you know of any thing to help me with this, that this other guy does not?

There is not 'dynamic' as such, but there is the Multiply Visu Element for creating many static objects
