R RapID™ Platfo orm – Modbu M usTCP Netwo ork Inte erface 2--Port Co onnectiv vity Solu ution The e RapID Platform P Network N Interface e is a com mplete, prre-tested solution that manages the industrrial protoc col and network n ttraffic forr a host processorr The Networrk Interface m module or embedded de esign contai ns everrything need ded to participate in starr, line, or tree network topo ologies includ ding the com mmunication ns controllerr, protocol sttacks, Flash h, RAM, Ethe ernet switch h and PHYs. A host proce essor conne cts to the N Network Inteerface via a UART or 16‐‐bit Parallel IInterface. A At the softw ware layer th he host conn nects to a “U Unified Interrface" so oth her protocols can be e used witho out changingg the host so oftware. Thhe work commu unications is extremely rrobust and supports Innoovasic's netw PriorrityChannel™ ™ technology. This means your field d device will operate prob blem‐free with any ModbusTCP conttroller and w will never dissconnect from m the networrk. Eas sy Hardw ware and Software S Integratiion The Networrk Interface can be integgrated into aa design as eeither a mod dule or an em mbedded de esign. As a m module, the Network Intterface plugs into a boarrd using stan ndard 2.54 m mm pitch thrrough‐hole ppins. on is as easyy as Wheen designing‐in the module, hardware integratio conn necting Powe er/Ground/R Reset and in nterfacing the Host to th e UART or 116‐bit Paralleel interface. As an embedded design n, the Netwo ork Interfacee hardware design can b be integrateed directly u using the scheematics provvided. Also p provided are e the Bill of M Materials annd example llayouts to m minimize the hardware desiggn effort. So oftware for tthe embedded design is provided ass firmware that is downloaded to th he flash. Wheether using the Network Interface ass a module o or an embeddded design, no software developm ment is requ uired and the ere are no liicense fees o or royalties.. Software inttegration with a Host is also easy. M Messages paassed betweeen the Host and Networrk Interface follo ow a “Unified d Interface” definition. A A simple to use, Innovassic supplied,, PC‐based to ool configurres the Network Interface, soo the Host o only passes p parameters b between it and the N Network Inteerface. From m this tool, itt is also easyy to specify how paraameters will be passed to o the ModbusTCP registter map and the assocciated host pparameters. Since the Host is only p passing paramete ers, the Hostt software does not havee to change if ModbusTTCP networkk parameterss change or iif another In ndustrial Ethernet protocol is uused. Theree is also a “so ockets” interrface that de is supports direct Etherrnet communication. Exxample C‐cod provided to minimizee the software effort forr the Host / N Network Interface communicaation. www.inno ovasic.com m R RapID™ Platfo orm – Modbu M usTCP Netwo ork Inte erface 2--Port Co onnectiv vity Solu ution Reliable, Fle exible Network Inttegration The RapID P Platform Nettwork Interfa ace supportss ModbusTC P communication with PriorityyChannel™ – – a revolutionary technoology that eliminates tthe effects o of network trraffic and ensures reliab le, real‐‐time network performance. It gives your devicce a significaant competitive advvantage, extrremely low jjitter, and a rreliable conn nection that will not discconnect eve en with >95% % network loading. P is a master//slave proto ocol with Mo odbus RTU ModbusTCP encaapsulated in a TCP frame e. The proto ocol requires slave devicees to respond to the m master's com mmands, and d these respo onses shouldd be perform med in a tim mely manner.. With PriorrityChannel’s extremely low latency,, ModbusTCP command s will not bee lost in unreelated netwo ork traffic and these comm mands will be e responded to with min nimum delayy. In addition n, the Netwo ork Interfacee comes with an example e Electronic D Datasheet file that can b be tailored t o describe the features of the field device to a Mod dbusTCP masster. To assiist with commissioning, a webserveer is provided d so the field d device’s neetwork inforrmation can be displayed d on a stand dard browserr. Fas st Evaluattion and Developm ment The RapID P Platform Nettwork Interfa ace Evaluatio on Kit provvides a quickk assessmentt for interfaccing a Host tto the mod dule. An app plication example is provvided in orde er to demonstrate end‐to‐end, Ho ost‐to‐Network Interface‐to‐ mastter commun nication. Sim mply connectt the Host deveelopment bo oard to the N Network Inteerface evaluaation boarrd via the UA ART or 16‐bitt Parallel intterface. Oncce Hostt‐side communication is established, ModbusTC CP communication can be evalu uated using a PLC or master ulator. The ccommunicattion path bettween Host and simu Mod dbusTCP masster can be ccompletely vverified befo ore integgrating the m module into your field device hardw ware.
