Definition of additional conditions (blocking flag)
A flag point with address and value(s) can be assigned to each reaction entry.
This blocking flag constitutes an additional condition that must be fulfilled before the
reaction is executed.
A reaction entry is said to be
blocked
if the current value of the flag
does not
correspond
to a value belonging to the entry.
Blocking Flag=. : $F10
Flag Value =Off : ?
Flag Value =(&,.,*,-,+=,-=,Off,Step 1,Step 2,Step
A specific value or a combination of several values can be entered for the flag value.
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 time reaction 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 TRR:
–
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.
