Your code will produce BO01 = True
If RI01 is = 0.0......then BO01 = 0
Any other value for RI01 will produce BO01 = True

Subject: [foxboro] Question about OR usage in CALC function block logic
Good day ladies and gents,
What happens in a CALC function block when an OR function is used with a stack
that includes a real value. For example, what is written out to BO01 in the
following case?
IN BI01; = False
IN RI01; = 13.0
IN BI02; = False
IN BI03; = False
OR;
OUT BO01 = ?
Does this produce an error? Does the result depend on the value of RI01?
I am reverse-engineering some old I/A logic and I do not have access to a
simulator to test and see what will happen in this situation. Can someone
please help me out?
Regards,
Quay
