2.16.2.2 Creating a new group reaction entry
Depending on the type of reaction program, the following prompts must be answered in
order to create a new reaction entry:
Definition of the "reason"
Reason for the group reaction can be given as a single address or an address range.
Number of the reaction entry. GRR entries are not sorted by addresses, rather by
address masks.
This prompt only appears if the address mask is specified. Only Data points with the
relevant message priority (MSGP parameter) are accepted.
Points with "MSGP=." do not come under this selection criteria.
The group reaction is activated by a status change of a single point or a point within the
above-defined address range:
"." Normal <--> Faulty
"1" Normal ---> Faulty
"0" Faulty ---> Normal
"." see the section below, Special Features
wherein ERSTA=0 corresponds to "Normal"
ERSTA=1 corresponds to "Faulty"
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 group 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 mask
Entry
Message priority
Edge
Blocking flag
Flag value
