FactoryTalk Numeric and Text Display

[DamianInRochester]

FactoryTalk View ME 5.10.00

I have a String Display object.

I want to concatenate a number and a string to display.

so in "Expression" i have

{numeric tag of type REAL} + "--" + {text tag of type STRING}

During runtime this generates an error
"Unable to activate connection:'my expression'"

Now if I delete the Numeric tag and leave the
"--" + {text tag of type STRING}
then it displays the two dashes and the text just fine

And if I delete the "--" and the STRING tag and leave the
{numeric tag of type REAL}
it displays the value of the number just fine

Is there any way to get it to display both??

I should also add that while in the expression editor the "check syntax" button returns valid on the expression that is giving me the error.

Can you just concatenate in the PLC? And have the string display in the HMI.

Instead choose Object - Drawing - Text

The screen will lead you through setting up the text. If you need a complex frame you can also make one of those then move the Text object on top of it.

Genius! Thank you Bernie, that worked like a charm.

Hi there! Sorry to hijack the thread but i have an almost related issue i cant seem to crack.. I have an object (VBA Exposed) that when pressed returns AB_CD_EF (ABCE etc. as example) as a string. I would like to append the controllername and a suffix to this and then use the whole as the expression of a numeric display to indirectly read a tagvalue from the PLC using the VBA, but i seem to get an error when assigning the concatenated string to the .Expression variable of a normal Numeric Display. Any ideas?

In RS Logix its showing real number but not showing on HMI.

You probably need to check the setting for the number of digits/decimal places for the numeric display.

A quick tip: you select the number of digits, and the number of decimal places, but the number of digits includes the decimal point.

So if you have a value of 2.4:
1 digit, 0 decimal places will read "2"
2 digits, 1 decimal place will read "2" (or more accurately, "2.", but it doesn't show the decimal place)
3 digits, 1 decimal place will show "2.4"
4 digits, 1 decimal place will show either "2.4" or "02.4" depending on your setting for what to do with leading zeroes
4 digits, 2 decimal places will show either "2.4" or "2.40" depending on your setting for what to do with trailing zeroes
5 digits, 2 decimal places, will show "2.4", "02.4", "02.40" or "2.40" again depending on your settings for leading and trailing zeroes.

Hope that helps!
