Siemens Building Technologies VISONIK DCS Functions and System Messages VVS18 CM2U8567E / 04.1999
Landis & Staefa Division Function GRR 2-155
The VISONIK DCS starts/stops one of the available DCS COLBAS tasks.
Number of the COLBAS task whose operation mode is to be modified.
Requested operation modes:
RUN Stops the COLBAS task if it is active, and starts it at the line number
entered.
RESTART Starts a COLBAS task only if it is inactive. If the task is active, the
instruction is ignored.
STOP Stops the task and prints a STOP message.
END Stops the task without a message.
Line number at which the task is to be started by a RUN or RESTART instruction.
No Reaction
(see the section below, Special Features)
This option is only implemented for group reactions and maintenance reactions.
Group reactions (GRR) and maintenance reactions (MRR) include additional
mechanisms that do not require a special reaction section:
•
Group reactions include a device changeover mechanism for alternative or auxiliary
devices.
•
Maintenance reactions include an operating hours counter.
If reaction programs are used for such cases, the reaction entry should be set to
"Reaction=.".
Automatic picture/point selection
When the reaction PICT is triggered, the VISONIK DCS automatically displays the
selected picture in VISONIK-Insight.
The picture is only displayed if VISONIK Insight is free. Otherwise, it is saved until it is
opened manually.
Specification of the picture to be displayed.
In the case of reaction programs whose "reason" is a point change (GRR/SRR), the
user can enter an "F" in the reaction entry instead of a fixed picture number. With this
entry the picture that has been assigned to the respective "reason" address using the
function COS,PICT (???) or the function PICT will be automatically displayed.
The PICT parameter contains the number of the picture on which a given point is
displayed.
VISONIK Insight, Output device number (T1..T15)
If a printer channel is selected as graphic device, the encoded picture number will be
printed only.
The VISONIK DCS executes the same reaction with the further addresses as with the
address defined under "Reaction =". This feature allows for reaction entries to be
economised.
The user can assign up to four different further addresses to each reaction entry,
provided the reaction is one that modifies point parameters
(Reaction =UA/TA) or prints slave messages (Reaction =SLV).
