1DeviceNet Communications for Series 90-30 DeviceNet ModulesDeviceNet uses the Producer-Consumer technique of messaging. A device with data produces thedata on the network. All devices that need data listen for messages. When a device recognizes theappropriate identifier, it consumes the data. A message is not specific to a particular source ordestination, and one message can be consumed by multiple devices. For example, one messagecould control several motor starter modules.A DeviceNet message field can range between 0 and 8 bytes. Messages longer than 8 bytes arefragmented into packets. The Series 90-30 DeviceNet modules assure data integrity for eachnetwork node.I/O MessagingI/O messaging is used for the routine and automatic exchange of data between devices. IndividualI/O messages can be up to 255 bytes in length. I/O messages provide a dedicated communicationpath between a producing device and one or more consuming devices. System configuration sets upthe parameters for the connections between the producing and consuming devices. With theconnections established, communications occur automatically.There are four basic types of I/O messages: Polled, Strobed, Cyclic, and Change-of-State (COS).The Series 90-30 DeviceNet Master Module can be configured for up to two different types of I/Omessaging connections to each slave (for example, one Cyclic I/O messaging connection and oneChange-of-State I/O messaging connection). See chapter 3, "PLC Configuration for the DeviceMetMaster" for details.Explicit MessagingExplicit messaging provide a point-to-point communication link between two devices on thenetwork. Explicit messaging is often used for slave configuration and for diagnostics. SpecificExplicit messages are defined for the DeviceNet protocol. For the Series 90-30 DeviceNet Mastermodule, Communications Request (COMMREQs) are used to send Explicit messages. See chapter6, "Programmed Communications" for more information. Received Explicit messages areautomatically processed by the DeviceNet module except for user defined Objects which requireuser programmed COMMREQs support.1-8 Series 90®-30 Programmable Controller DeviceNet Modules – November 2002 GFK-2196
Chapter2InstallationThis chapter provides basic installation information for the Series 90-30 DeviceNet Modules:• Power requirements: PLC system power and DeviceNet network power• The DeviceNet cable: specifications, length, termination, taps• Grounding: DeviceNet cable, DeviceNet power supply, DeviceNet system• Installing the DeviceNet module in the PLC• The Module LEDs: Module Status, Network Status, Network Power• The RS-232 Serial PortFor Additional InformationCorrect installation of cables, power supplies, and other network hardware requires a more detailedknowledge of DeviceNet specifications than can be provided here. Readers are referred towww.ODVA.org for additional information.Conformance to StandardsBefore installing GE Fanuc products in situations where compliance to standards or directives fromthe Federal Communications Commission, the Canadian Department of Communications, or theEuropean Union is necessary please refer to GE Fanuc’s Installation Requirements forConformance to Standards, GFK-1179.GFK-2196 2-1
