Converting Text to String Tag in Siemens PLCs

You can convert concatenated text into a string tag (Text variable 8-bit) using VBScript within your Siemens PLC program (e.g., in a Function Block or Function). Here's how:

VBScript Example:

Dim strTag1, strTag2, strConcatenated, strResultTag
strTag1 = "Hello"
strTag2 = "World"
strConcatenated = strTag1 & " " & strTag2 'Concatenate strings
strResultTag = "YourStringTag" 'Name of your string tag
'Assuming "YourStringTag" is a global text tag defined in your PLC
'Assign the concatenated string to the string tag.
PLC_Tag(strResultTag) = strConcatenated

Explanation:

• `strTag1` and `strTag2` hold the initial string values.
• `strConcatenated` stores the result of the string concatenation.
• `strResultTag` is the name of the 8-bit text tag you've already defined in your PLC project.
• `PLC_Tag(strResultTag) = strConcatenated` assigns the value of `strConcatenated` to your PLC string tag.

Important: Make sure the `strResultTag` variable name matches exactly the name of your pre-defined text tag in the PLC's tag table. Also, ensure the string tag is large enough to accommodate the concatenated string.
