Function
Calculates the average value
of latest n scan values of A ,
and stores the result in C .
Filters the value of A by filter
constant specified by B , and
stores the result in C .
Performs PID control. (pre-
derivative real PID algorithm)
Process value (PV): A
Set value (SV): A+1
PID parameters: B and after
Manipulation value (MV): C
Upper limits the value of A by
B , and stores the result in C .
Lower limits the value of A by
B , and stores the result in C .
Finds the maximum value of n
registers data starting with A ,
and stores the value in C and
the pointer in C+1 .
Finds the minimum value of n
registers data starting with A ,
and stores the value in C and
the pointer in C+1 .
Calculates the average value
of n registers data starting
with A , and stores the result in
C .
Finds f(x) for given x= A , and
stores it in C . The function f(x)
is defined by parameters
stored in a table 2´ n registers
starting with B .
