2-130 Function DRR Landis & Staefa Division
In the above example, the reaction entry is executed only if the "reason" is fulfilled and
flag $F10 has the value 1,Step or 2,Step at that time.
In all other cases the reaction entry is blocked, and the reaction is not executed.
Definition of the reaction to be executed
The following reactions can be triggered via a date / time reaction register entry:
Reaction =(UA,TA): ?
UA/TA = Change Point Parameter
CT = Printout Cleartext
MC = Issue MACRO Command
SLVM = Output Slave Message
CB = Start/Stop COLBAS Task
. = No Reaction (for MRR & GRR)
PICT = Auto Picture/Point Selection
Reaction =(UA,TA):
Address of the data point on which the reaction is to act. The following inputs are
permissible:
•
Technical address or $* masks
•
User address or $* masks
•
All addresses, including CT to PICT, by entering '..' (???)
Specify the parameter to be modified.
In the example "Set Digital Output: Priority=0 :"
The following possibilities are available for entering the parameter value:
•
A fixed value is assigned to the selected parameter.
•
A priority is assigned to the resultant output values RDO of switch command points
DO.
The following variants can be entered for switch commands in the DRR:
–
Modification of the parameter DO1 or DO2 with its respective bit influence DO1ACT
or DO2ACT.
–
Selective setting of a single bit influence in DO1ACT or DO2ACT.
–
Selective setting of all bit influences in DO1ACT or DO2ACT.
The above statements apply analogously to flag points.
•
RVAL
: The resultant setpoint of a switch command RDO or of a flag point RFL is set
to the last effective value, e.g. after a power failure.
•
SAME
: When the reaction is triggered, the parameter value of the reaction address is
set the SAME as the main value of a selectable data point.
The data point can be specified at the "FNT /Address" (???) prompt.
•
INV
: When the reaction is triggered, the parameter value of the reaction address is
set to the INVERSE of the main value of a selectable data point. The respective
values are interpreted as Boolean variables.
The data point can be specified at the "FNT /Address" (???) prompt.
•
More detailed information and appropriate examples can be found in the chapter
"Reactions" in tab "R" of this manual.
•
Information on the subject of "bit influence" can be found in the descriptions of the
parameters RDO,DO,DO1,DO2 and RFL,FL,FLI1,FLI2.
When the reaction is triggered, the VISONIK DCS prints a specific clear text message in
the defined message mask; the message appears in the language that is defined for the
respective device with the parameter XX.
