10 Programs for logic and control
10.1 Flag Input/Output
Programming logical connections with combinable time responses
Interrogation of specific conditions such as a module fault and AF activity
Note!
Enhanced information regarding AF channels (
Audio channel
) in a
Flag
can be transferred from
each (
Flag (OR)
) input to the (
Flag (OUT)
) outputs! Combined with the capability of most AF programs to
exchange AF channel information by means of
Flag (OR)
and
Flag (OUT)
, it is possible to program
complex AF channel switch-overs.
The AF channel of the first flag to become active in the output is
always taken over!
Procedure:
The output of the program becomes active, if the input and timer conditions permit this!
Only inputs in which a
Flag
or a
Line
is entered, are taken into account. Inputs with a 0-entry are ignored.
At
least one
Flag (OR)
must be programmed and
active
in order for
Output active
to be possible. For
continuous activation, the
Flag
255 (
Always ON
) is available.
The
Flag (OR), Line
inputs and the configurable special input are OR linked.
Input conditions:
The field of an OR-link fulfills the condition for itself alone.
A
Flag (AND)
must be used in conjunction with at least a
Flag (OR)
. AND and OR must be active
in order to fulfill a the condition.
An active
Flag (NAND)
switches off independently of other inputs immediately. Only the use of
Timer 2 or Timer 4 delays switch-off after Follow-up time T1.
Flag (OR)
[IN] The program can be switched on by this flag. It is possible to take over AF
channels.
Flag (AND)
[IN] AND link with
Flag (OR)
Flag (NAND)
[IN] The program can be turned off by this flag or switching on can be prevented.
Selection box
Special input (see next table)
Input
Address, port and line from a module
Flag (OUT) 1/2
[OUT] The flag is switched on if the program is activated. Other programs can be
triggered. It is possible to transfer the AF channel in use.
Flag (OUT) (invers)
[OUT]
Flag
ON in idle position
Output
Address, port and line to a module
Output (invers)
Address, port and line to a module (ON in idle position)
