3.2.6 Function
diagram
The following diagram shows in which order the functions are processed:
Switching command
Evaluate logic operation
Evaluate time function
Evaluate forced operation
Evaluate cyclic monitoring
of object “Telegr. switch”
Evaluate relay operation
Objects
- “Switch”
- “Call preset”
- “8-bit-scene”
- “Threshold value”
Objects
- “Log. connect. 1”
- “Log. connect. 2”
Cyclic monitoring of
object “Telegr. switch”
Object
“Priority / forced op.”
UND
ODER
XODER
Tor
Staircase lighting function
ON/OFF delay
Flashing function
Fault mode when object
“Telegr. switch” is omitted
Forced operation active /
inactive
Normally closed contact /
normally open contact
Switch relay
Command input:
Fig. 5: Interdependence and priority of the functional groups
Example: On receipt of a “Logical connection” object, the linking logic is
evaluated first of all. The result is analysed by the time function;
when the staircase lighting function is active, this can result in
the staircase lighting being switched on.
The forced operation has the highest priority as it is evaluated last of all the
functions.
