

TheMDC‐700seriesmoduleisaModbusDataConcentratorwhichcanconcentratedatafrom

severalModbusRTUslavedeviceswithRS232/RS‐485interfaceandallowsModbusTCPmastersto

read/writedataviaEthernet/LAN.TheModbusmastercanuseoneModbuscommandtogetalldata

onthoseModbusRTUslavedevicesviatheMDC‐700concentrator.Inotherwords,throughthehelp

ofaMDC‐700module,theModbusRTUslavedevicescanbeaccessedoverEthernetwithbetter



IfyouwouldliketowritedatatoadigitaloranalogoutputchannelonaModbusRTUslavedevice,

theoutputchannelneedsbemappedwithalocalregisteraddressintheMDC‐700byeditingthe

pollingdefinitionwithusingcorrespondingreadfunctioncode(01or03).RefertoSection6.FAQ‐Q4

formoredetailedsteps.



ThefollowingsectionwillhelpyoutosetupyourMDC‐700module.Aftercompletingthefollowing

steps,youcanobtainconfigurationandotherinformationrelatedtotheMDCmoduleand

associatedslavedevicesinyourbrowser.



Basicoperatingprocedure

Step1:AssignavalidIPaddresstotheMDC‐700.

Step2:Edittheconfig.csvfile.

Notethatbeforeeditingthisfile,youshouldconfirmtheparametervalueforany

associatedSlavedevices.

Step3:Uploadtheconfig.csvfiletotheMDC‐700.

3.1.AssigninganIPaddresstoMDC‐700

TheMDC‐700isanEthernetdevice,whichcomeswithadefaultIPaddressof192.168.255.1;

therefore,youmustfirstassignavalidIPaddressofyournetworktothemodule.Toaccessthe

MDC‐700byusingweb‐basedinterface,youhavetoknowtheIPaddresssettinginthemodule.



STEP1:ConnectthePCandMDC‐700moduletoanEthernetHub/Switch,andpoweronallthe

devices.YoucanalsoconnectaMDC‐700toPCdirectlywithanEthernetcable.



STEP2:SettheIPconfigurationonyourcomputer.

IftheMDCmoduleisnewwithusingthedefaultIPaddressof192.168.255.1,youmustchose

anIPaddressforthecomputerintherangeof192.168.255.2–192.168.255.253thatisnot

alreadyinuse.



NOTE:DetailsonhowtochangetheIPaddressonyourcomputerdependuponthetype

architectureandoperatingsystemyouareusing.UsetheHelpandSupportfunctionalityon

yourcomputerandsearchfor"IPAddressing".



STEP3:Openawebbrowserandgotothewebsiteathttp://192.168.255.1,where192.168.255.1is

theIPaddressinyourMDCmodule.



STEP4:Confirmtheconnectionstatusiconisopenonthepage.





DenotestheconnectionbetweenthecomputerandtheMDC‐moduleisopen.



DenotestheconnectionbetweenthecomputerandtheMDC‐moduleisfailed.



STEP4:ChooseavalidIPaddressofthenetworkforyourMDC‐700module

Scrolldownto‘EthernetConfiguration’section,inputtheIP/SubnetmaskandGateway

addressesandclickonthe“Apply”button.MakesurethattheIPaddressyoupickisnot

currentlyinusebyanotherdeviceonthenetwork.



NOTE:TheIP/Subnetmask/GatewaymodifiedinaMDC‐700canberesettofactorydefaults

byshortingtheRESETpintoGNDpinover3seconds.TheLEDdisplaywillshow“RESET”as

belowandtheIPaddresssetpreviouslywillbeclearedandreturnedtothefactorydefault.



3.2.Editingtheconfig.csvfile

TheMDCmoduleisconfiguredbyaconfig.csvfiletoworkwithyourmasterandRTUslavedevices.

TheCommaSeparatedValues(CSV)filescanbeviewedandeditedinspreadsheetapplicationslike

MicrosoftExcel,orinanytexteditor,inwhichthecommacharacter(,)typicallyseparateseachfield

oftext.Inatexteditor,itlookslikethis:



Thefilename“config.csv”cannotbechanged;itcontainsfourmainsectionsthatneedtobeedited:

(1)ModbusConnection,(2)Moduleinformation,(3)COMPortConfigurationand(4)Polling

Definition.Eachsectionstartswitha“#”character;followsarenamesforparametersinthissection.

Arowstartingwitha“*”characterisasetofsettingsinasection.

NOTE:

Thenameforeachparametercannotbechanged.

Youcanmakeacopyoftheconfig.csvfileinthreewaysandmodifyittomeetyour

requirements:

1.Exporttheconfig.csvfileinyourMDC‐700.(See3.3.Importing/exportingtheconfig.csvfile)
