I need pass a string value to a custom function.  Is there any way to declare a type for custom function parameters??

I am assuming you mean using URScript on the UR Robot, if not please clarify.

If you write your function correctly you can just pass it.  The type is inferred the first time the variable is instantiated and then the type becomes static.

Here is a simple function that I wrote that passes the string to another global variable and then uses it to create a popup.

So since global b is already a string type before the function is called, the a variable takes on the type of the global b?

What I have is a communication function that talks to a device, and it needs the IP address and port to grab the data.  The IP address is a string, the port is an integer.  So somewhere in the program, set a global ip variable as a string?

def myCommFunc(ip,port):
# connect to device, grab data

return data
end

Not sure what I did wrong, but started over and it works.  Thanks for the explanation!

You’re welcome.
