5 Commissioning the PLC programming environment5.2 For Modbus/TCP50 SmartWire-DT Gateway EU5C-SWD-EIP-MODTCP 08/17 MN120003Z EN www.eaton.com5.2.2 Using gateways with ELC/Modicon controllersDepending on the controller system being used, it is possible that the sys-tem will not be able to process all the data with one single Modbus request.If this is the case, please use multiple read/write requests in order to makesure that all data is processed.5.2.3 Using gateways with Eaton controllersEaton controllers (XC20x) and HMI displays with a PLC runtime functionalitycan be used as Modbus-TCP servers and clients. The library required for thispurpose must be imported into the XSoft-CoDeSys programming software'slibrary manager. Please read application note AN2700K22, "Modbus/TCPMaster/Slave for XControl Controllers." This application note contains notonly the corresponding documentation, but also the required library.￫ The application note can be downloaded on the Internet at:ftp://ftp.moeller.net/AUTOMATION/APPLICATION_NOTES/Index.html
