1.Introduction



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

readandwriteperformance.



TheMDC‐700seriesmodulehastheabilitytoperformupto240ModbusRTUcommandsto

read/writedatafrom/toModbusRTUslavedevicesandallowsupto8ModbusTCPmasterstoget

thepolleddata.ThesupportforModbusTCPprotocolmakestheMDC‐700wellintegratedinto

PC‐basedapplicationssuchasSCADA(SupervisorControlandDataAcquisition)andHMI(Human

MachineInterface)programs.

Byusingaregularwebbrowser,userscanchangetheIPaddress,import/exportthe

configurationfile‐config.CSV,checktheaddressmappedforpolleddataandconnection

statusofeachpollingdefinition.TheMDCfirmwarewillskiptheabnormalModbus

pollingdefinitionforawhiletosmoothlyperformthewholepollingwithoutdistribution.



GreatCapabilityofSharedMemory

TheMDC‐700seriesmodulecanperformupto240pollingdefinitions.Andthe

internalsharedmemoryhasfourtablestostorethepolledAI,AO,DIandDOdata.

Eachtablecanstoreupto9600registers.

SupportforModbusTCPMasterandModusRTUMaster

TheModbuspollingdefinitionisdefinedinaConfig.CSVfile.Editing/checkingalotofpolling

definitionsisahardworkanditmaybemakingmistakes.ACSVformatfilecaneasethework

byusingExcel.Furthermore,thebuilt‐inwebserverallowsuserstoimport/exportthe
