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.
[IN] The program can be switched on by this flag. It is possible to take over AF
Flag (OR)
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
[OUT] The flag is switched on if the program is activated. Other programs can be
Flag (OUT) 1/2
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)
