SCL INSTRUCTION
FOR ANALOG INPUT:-
In case of
Micrologix -1000 A for current signal (4 to 20 mA),
Max Value for
i/p = 31230 (Approx.)
So min value
at 4 mA = 31230*4/20 = 6246 (Approx.)
Let the range
of RTD is 0 to 400 degree C.
To calculate
the value of rate & offset please use following formula.
1). Rate = (scaled
max. - scaled min.) * 10000 / (input max. - input min.)
= (400 – 0) * 10000 / (31230-6246)
Rate
= 160
2). Offset = scaled
minimum - (input minimum x rate)
= 0 – (6246 * .0160)
Offset = -100
FOR ANALOG OUTPUT
In case of
Micrologix -1000 A for current signal (4 to 20 mA),
To use the AI
double click on I/O Configuration & then I/O Setup.
Select the
o/p mode (may be current or voltage, which you want to use).
If you want
to provide 0 to 10 V signal on o/p then the value at O:0.4 should be 0 to 31230
(Approx.).
