Can somebody suggest a solution to my problem with the algebra please. The structure of my formula is wrong
I am working on an electrical system. I have created a calculation, which identifies a fault when certain conditions occur. (r1 is a text filed which may contain numbers)
In the case of live CSA = 2.5 only. A fault is generated
when the OPD = 32amp
and r1 ≠ LIM or Number
and rn ≠ LIM or Number
and r2 ≠ LIM or Number.
My formula construction is not correct.
If ( Cable Ratings Data Source::Rating = 2.5
and OPD Ratings Data Source::Rating = 32
and ( IsEmpty ( Filter ( R1 Ring Line Impedance ; "0123456789" ) ) or R1 Ring Line Impedance ≠ "LIM" )
; "Fault" ; "Okay" )
