iTrax Spray Controller6Part 1079459-07 2017 Nordson CorporationiTrax Systems (contd)The Spray Controller, Spray Monitors and PRx modules are connected to asingle CAN network.The iTrax Operator Interface (OI) is provided as a local OPC client or, as anoption, a remote OPC client. Each module has an independent embeddedprocessor, so once they are set up on the CAN network, they do not requirethe Windows computer to function.The CAN network is an industrial standard differential serial bus designed tobe robust in electromagnetically noisy environments.The iTrax System uses a Nordson proprietary data protocol, so onlyNordson modules can be on the network.External data exchange is provided from the OPC Server. OPC is anindustrial standard that specifies the communication of real−time plant databetween control devices and computers from different manufacturers. TheNordson iTrax OPC Server is OPC DA 2.0 compliant.iTrax Software PackageThe iTrax Software Package is required for setup and contains the OPCServer, and OPC Local Client applications.The OPC Server collects data from the modules on the CAN network once asecond and organizes it per module inputs and outputs. This ”raw” data canbe viewed within the server application.The OPC Local Client (the iTrax OI) is included on the same CD with theOPC Server. It runs on the same computer as the OPC Server. Theoptional OPC Remote Client (remote iTrax OI) is a remote window into thesystem. It provides operators or managers the ability to run or monitor theiTrax System from remote computers on a factory installed Ethernetnetwork. The system can also have the following options: Local or Remote OPC data logging software package Pressure regulators, proximity switches, and other sensors for optionalsystem control and monitoring CAN-to-CAN gateways, for very long networks requiring electricalisolation or systems with a large number of modulesOptional OPC Remote ClientThe optional OPC Remote Client application allows the iTrax system OI tobe viewed and operated on additional computers on your ethernet network.Talk to your Nordson representative about adding this option to yoursystem.
