Processing details

■Engineering value conversion processing

This function block executes range conversion to the value input from the input variable IN and outputs the result from the

output variable OUT_.

Output (OUT_)

(OUT_NMAX-OUT_NMIN)×(IN-IN_NMIN)

IN_NMAX-IN_NMIN

OUT_NMAX: Output High Limit Alarm

OUT_NMIN: Output Low Limit Alarm

IN: Input value (IN_NMIN to IN_NMAX)

OUT_: Output value

This expression is also applicable for OUT_NMAX  OUT_NMIN and N_NMAX  N_NMIN.

Operation error

An invalid operation (such as division by zero) is performed.

Input data (IN) or operation constant (IN_NMAX, IN_NMIN, OUT_NMAX, OUT_NMIN) is a subnormal number or NaN (not a number).

An overflow has occurred.
