7 Modbus/TCP – SmartWire-DT implementation7.1 Overview of Modbus registers74 SmartWire-DT Gateway EU5C-SWD-EIP-MODTCP 08/17 MN120003Z EN www.eaton.com7.1 Overview of Modbus registersThe input and output register space makes it possible to access the gate-way's data in a structured manner. Tabelle 23 below lists the available regis-ters, together with their contents and address ranges. A detailed descriptionof the registers is provided afterwards.Table 23: Overview of Modbus registersModbusregister, hexa-decimalRead/WriteData type &Value DescriptionSmartWire-DT input/output data0x0000 - 0x03FF R WORD 0 - FFFF Input data (input register, input status)0x0800 - 0x0BFF R/W WORD 0 - FFFF Cyclic output data (holding register, coilstatus)0x1012 R WORD 0 - 5136 Bit-length of the digital outputs0x1013 R WORD 0 - 6400 Bit-length of the digital inputs0x1017 R WORD 1 Version of "mappings" registerGateway device information0x1000 - 0x100B R STRING EU5C-SWD-EIP-MODTCPName of the gateway0x100C Status of the gateway￫ Section “ Register0x100C: "Gateway-Status“”, page 76Time Tracker0x1020 R WORD 0 - FFFF Active time monitoring (in milliseconds)0x1120 R/W WORD 0 - FFFFDefault setting:3000(= 3 seconds)Defined time monitoring (in milliseconds)0x1121 R/W WORD 0 - FFFF Time monitoring for the "Reset" register0x1130 R/W WORD "Modbus connection" operating mode0x1131 R/W WORD 0 - FFFFDefault setting: 0Time monitoring for Modbus connection (inseconds)0 = No time monitoring0x113C - 0x113D R/W WORD Used to restore the Modbus connectionparameters0x113E - 0x113F R/W WORD Used to save the Modbus connection param-etersAcyclic SmartWire-DT data0x8000 - 0x807F Request space for acyclic service objects￫ Section “7.5 Acyclic data communica-tions”, page 780x8080 - 0x80FF Results space for acyclic service objects￫ Section “7.5 Acyclic data communica-tions”, page 78
