Landis & Staefa Division Function PNX 2-225
2.25 PNX Change/List Multiple Point Parameters
The function PNX provides the user with highly flexible means to
• •
change parameters
and/or
• •
list parameters
of a large number of points in great detail and according to complex constraints.
The function PNX is a useful extension to the functions PG, PNT and RPT.
It is related to RPT,PNX, except that it allows parameters to be changed.
2.25.1 Initial Access and Handling
CRTL/P, PNX
Before the desired parameter changes can be made, the set of points, i.e. the address
range and the constraints, as well as the operating mode must be specified:
The functio.n PNX allows the following sets of points to be selected:
1.
up to 7
address ranges or individual addresses
2.
up to 8
masking parameters (parameter name with respective value)
3.
up to 10
freely definable parameters to be changed or printed.
Note:
The above maximum selectable values cannot all be specified at the same time.
The user is free to select any of the following options or any combination of them:
•
Selection of the parameters to be changed according to the above criteria
•
Status report for all selected parameters
•
Statistics on the number of points found
Example of the function PNX
T8 15:20:10 Function=PNT : PNX
1. Address Mask=$d100'000...$d100'377: $100*
2. Address Mask=. :
1. Masking Param.=.: ?
PAR = "AND" Parameter
!PAR = "OR" Parameter
. = -----
1. Masking Param.=.: OSV
Parameter Value = 0: ?
General: Operation and Value or Only Value
Operations for Numerical Values (x,y):
x(..y) Equals x or within x..y (default)
<>x(..y) Does not equal x or outside x..y
>x, >=x Greater than x, Greater than or equal to x
<x, <=x Less than x, Less than or equal to x
Operations for Bitset Values (x,y):
x&y Equal - Only Bit x,y set (default)
<> x&y Unequal - Only Bit x,y not set
and x&y AND Expression - Bit x and y set
or x&y OR Expression - Bit x or y set
not x&y Inversion - Bit x,y not set
