In the
example
below, a compare function as boiler thermostat shall issue the message "excess
temperature" to set off an acoustic warning signal when excess temperature is in the boiler (=event),
switch on dominantly the heating circuit pump and the cylinder charging pump and switch off the
burner demand:
INPUT VARIABLE:
OUTPUT VARIABLE:
MESSAGE TYPE:
Header selection: MESSAGE, FAULT, WARNING, ERROR
WARNING
A warning is issued
MESSAGE GROUP:
What group was the name of the message selected from?
Default
General or user-defined (only with TAPPS)
MESSAGE CAUSE:
What event caused the message to be issued?
Excess temp.
Excess temperature triggered the message
WARNING TONE yes
As soon as this event occurs, a warning tone is issued
In addition, appears as the message type "FAULT":
Reset fault?
Pass on the scroll wheel to set off a pulse that last three seconds
in the output variable "Reset fault"
The respective pump outputs are darkened to show that they are assigned in the output variables
under the heading "OUTPUT (dominant ON)." This ensures that the pumps are always reliably
switched on when the event occurs. At the same time, assigning this output for the burner demand via
"OUTPUT (dominant OFF)" ensures that the burner is switched off in all cases.
In general:
If outputs are triggered by means of "dominant" commands (even for other modules that
have such options), all control signals from simple assignments are overwritten --
including manual
mode
. If two different dominant signals come into an output at the same time (ON and OFF), the
signal "dominant OFF" has priority.
If the event sets off the message as described above, the function overview will begin with:
---------------------
WARNING TONE OFF:
---------------------
WARNING
Excess tTemp.
since:
29,01.
at 15:18
DELETE MESSAGE:
---------------------
Is not displayed if the event is still current
As soon as the cursor is on "
WARNING TONE OFF
", press the scroll wheel to switch off the acoustic
warning signal and delete this line from the display.
Only for the message "
FAULT
": The additional line "reset fault?" sets off a pulse that lasts for three
seconds with the scroll wheel in the output variable "Unlock Malfunction" regardless of whether the
event to trigger this reaction is still current at this point or not. If this event no longer occurs after the
pulse, the entire message is deleted at the same time.
