4.6 Digital out: external reset alert
ExternalresetalertisactiveduringtheconguredPre alert time before an automatic reset of motor protector
isperformed,oralarmsareresetfromadigitalinputtypeAlarm reset withresetdelay>0.
Example: Thepumpsareblockedbecauseoneorseveralalarms.
Aremotealarmresetmaycauseablockedpumptostart.Ifservicesta󰀨arenearbytheycouldbenotiedbya
sirenorashinglightconnectedtothedigitaloutput,thatapossiblepumpstartispending.
4.7 Communication
Therearethreeportsforcommunication.OneUSBandtwoRS232,ofthesetwoRS232thereisonlyone
which can be connected to a modem. The protocols are Modbus RTU or Comli. Other protocol could be avail-
ableifthereisanexternalconverterfromModbusorComlitorequestedprotocol.
4.7.1 Com port (screw terminals 48 – 52)
This port is designed for modem communication and supports Modbus RTU or Comli protocols. Other protocol
suchasTCP/IPcanbeusedbyusingmodemwhichconvertsthesignal.TheportisconguredasModbus
RTUdefaultwithbaudrate:115200,parity:None,Handshake:O󰀨,andProtocolID:1,Messagetimeout:2s
Optional:Stationname.
Onthisporttherearepossibilitiestochangethepropertiesofbaudrate(300–115200),protocolID(1–255)
andstationID(1–65535),Parity(None,Odd,Even)andhandshake(on/o󰀨)aswell.NecessaryforAquaWeb
connection is the Station IDsetcorrectlyandthattheprotocolIDissetto1!
4.7.2 Service port (9-pols D-Sub in the front)
Thisportfollows“Com port”inprotocolandhasalwaysprotocolID:1therearehoweverpossibilitiestochange
the properties of baud rate separate from Com port.Thisportisconsidertobeusedfordownloadcongura-
tionandupdatingthermwarebyusingAquaProg.
4.7.3 USB port (USB type B in the front)
Thisportisfollowingtheprotocolfrom“Com port”andisonlyforupload/downloadcongurationbyusing
AquaProg.
4.7.4 Modem
Only the port at the screw terminals (Com port) is supporting modem.
Thereareanumberofdi󰀨erentmodemswhichcanbeusedonPC441.
NormallyisaCA521connectedtothePC441whichcallsbyGSMtoaSCADAtriggedbyaneventorthata
SCADAcallsupforcatchinglogvalues.IfPC441isconnectedtoAquaWeb,thenshalltheCA521beworking
asaGPRSmodem.It’salsopossibletoconnectaTCP/IPoranalogmodem.
TCP/IP modem ForxedTCP/IPline.CommunicationthroughRS232toexternalIPmodem.Thisiscomparabletoadirectline
and in the settings under Communication – Modem – Modem connected in the PC 441 shall be [No].
Analog modem Forxedtelephoneline.Signalsbeforeanswer,minimum1.Hayessettingsnormallyworkswithdefault.
Settings under Communication – Modem – Modem connected in the PC 441 shall be [Analog modem].
GSM modem ForGSMconnectione.g.CA521.Signalsbeforeanswer,minimum1.
 Hayessettingsnormallyworkswithdefault.SetPINcodeifSIMcardisequippedwithone.Settingsunder
Communication – Modem – Modem connected in the PC 441 shall be set to [GSM modem].
NOTE! ThePINcodecanbedeletedwithacellphone.
GPRS modem BasedoninternalTCP/IPstackinCinterion(formerSiemens)GSM/GPRSmodules.Alldataaccessisviathe
 HayescommandsdenedbyCinterion.MostcommonisdynamicIPaddressing.GPRSdefaultisthepump
controllerconnectstoTCPserverinSulzerAquaWebsystem.IfScadasystemshouldconnecttostationsee
TCP-serversection.CommunicationviaGSMandGPRSusesthesamenetwork.Ifsubscriptionallows,both
canbeusedoneatatime.SetPINcodeifSIMcardisequippedwithone(deletedonAquaWebSIMcards).
NOTE! ThePINcodecanbedisabledwithacellphone.
