Vereinfachte Liste der Modbus-Netzwerkvariablen

Die vereinfachte Liste Modbus enthält die am häufigsten verwendeten Daten für die Überwachungskommunika-
tion in Modbus. Alle diese Datenpunkte können über den Corrigo Controller ausgelesen werden. Die verfügba-
ren Informationen hängen von der Konfiguration der Anlage ab. (Betriebsart oder gewählte Optionen, Montage /
Verkabelung usw.)

READING AIR FLOW /PRESSURE
In COP mode with pressure transmitter on supply air duct =
Value of ∆Pa mesurement on supply air fan nozzle
Air flow is obtain by calculationl: Air flow= K*√ ∆P
R
Coef.K value corresponding to the unit; √∆P= √read value/10
Value: 0 .. 9999 signifiant 0 .. 999.9Pa
Supply air flow (M3/h), in CAV, VAV ou COP on exhaust air
R
running mode
Pressure on supply air fan (Pa), in COP on supply air duct
R
Value: 0 .. 9999 means 0 .. 999.9Pa
In COP mode with pressure transmitter on exhaust air duct =
Value of ∆Pa mesurement on supply air fan nozzle
Air flow is obtain by calculationl: Air flow= K*√ ∆P
R
Coef.K value corresponding to the unit; √∆P= √read value/10
Value: 0 .. 9999 signifiant 0 .. 999.9Pa
Exhaust air flow (M3/h), in CAV, VAV ou COP on exhaust air
R
running mode
Pressure on exhaust air fan (Pa), in COP on supply air duct
R
Value: 0 .. 9999 means 0 .. 999.9Pa
Status of boost function
R
0=boost off; 1=boost on
TEMPERATURE STATUS
Read the supply air temperature
R
Value: -990 .. +990 means -99.0 .. +99.0 °C.
read the exhaust air temperature
R
Value: -990 .. +990 means -99.0 .. +99.0 °C.
Read the outdoor air temperature
R
Valeurs: -990 .. +990 signifiant -99.0 .. +99.0 °C.
Read the water coil temperature (anti frost probe value)
R
Valeurs: -990 .. +990 signifiant -99.0 .. +99.0 °C.
