CM2U8567E / 04.1999 VISONIK DCS Functions and System Messages VVS18 Siemens Building Technologies
2-228 Function PNX Landis & Staefa Division
2.25.2 Parameter Change/List Operating Mode
The function PNX allows parameters to be changed in two different ways:
–
Allow the VISONIK DCS to automatically change the complete selected point set to a
specified value.
–
Manually change each value, point by point, to a new, freely selectable value.
The system carries out each parameter change in the sequence of entered operating
parameters. Any parameter that does not apply to a point in the specified point range is
skipped (e.g. HIL for a switch command point).
With "Operating Param. =." the respective parameter is not changed, and the points in
the selected address ranges are only listed when a status report is requested by the
user.
Operating mode
The change/list operating mode can be selected by entering the appropriate
abbreviation.
The operating mode can be extended as required by any meaningful combination of
abbreviations (e.g. CHP&INSP, etc.).
Within the specified address range and for the selected parameters, the operating
modes have the following significance:
List Parameter
The VISONIK DCS lists the selected parameters for each point address.
Change Parameter (Fixed Value)
The VISONIK DCS automatically changes all selected parameters to the specified
value.
Important: A list is not automatically printed with CHA. In order to produce a list, the
options CHA and LIST must be combined, i.e. CHA&LIST.
Change Parameter (Point by Point)
The selected parameters can be set manually to individual values, point by point.
Important: A list is not automatically printed with CHP. In order to produce a list, the
options CHP and LIST must be combined, i.e. CHP&LIST.
Possible application: assigning user addresses after point generation with the function
PG.
Inspect before Parameter Change
This option allows the user to verify each parameter change before it is made, and then
confirm or cancel it with "Change =(NO, YES)".
The INSP option can be deselected at any time by entering "Change =.". The VISONIK
DCS then continues the process in the selected operation mode without inspection.
Parameter Change Messages (MSGDEV)
All parameter change messages are registered at the terminals specified in the
parameter MSGDEV (message channel mask).
Parameter Change Messages (DEVPCH)
All parameter change messages are registered at the terminals specified in the
parameter DEVPCH (message channels: manual parameter change)
