Hello
What would be the best way to write a value into "Source B" of a GEQ SLC500 PLC instruction from Wonderware?

I would like the operator to be able to change these values from within Wonderware


thanks,
 
Use an unused Integer or Floating Point address. Then have the HMI write to that tag. In my example I am using N10:0 to hold the value from the HMI. Then I move that to N11:0 as my "valid number".

This allows me to test that the value from the HMI is within a range.
