Hi Asif,

 

Just to clarify, are you asking if you can count the number of times a value is read from a particular memory address while running your project? Or are you asking how you can count the number of explicit references that have been defined for a specific memory address in your project?

 

Additionally, what is the specific model of your PLC and how are you communicating with it?

 

Best,

You might be able to count the instances of a specific shared variable with scripting. It wouldn't be easy. And if you succeed, it will not work in an executable.

Do you know how to use Google search? Just search for "VI scripting" or "LabVIEW scripting" keywords.
