runScript on expression tag produces Bad_Stale value

Ignition
1

I am trying to use an expression tag to produce a random value every 30 seconds in Ignition 8.0.5 using a the runScript expression and a script called randomInt written in a global project. For some reason it is producing a Bad_Stale value and I can’t figure out why. Here is the global script.

import random

def randint(lower, upper):
return random.randint(lower, upper)

Here is my runScript expression:

runScript(“randomInt.randInt”, 0, 0, 160)

You say this is a global project. But is it the “Global Scripting Project” as identified in the gateway’s configuration?

3

yes it is.

Consider putting some logging statements in your randInt function that will show the values passed.

5

Also look in your gateway logs for syntax error reports for your script modules. You only get one of those per save.

Ok thanks. I will do that.
