DeviceNet Modules, Series 90-30, Manual, GFK-2196

3Configuring the Parameters of a DeviceNet Master ModuleThe DeviceNet Master Module is added to the PLC configuration in the Navigator window, and themodule’s Parameter Editor window appears in the InfoViewer window space.Parameters of a DeviceNet Master ModuleSettings tabMac IDSlave Status BitArray AddressLength(of slave statusbits)NetworkStatus/FirmwareID AddressLength (ofnetwork status/firmware ID)Program ModeTransmissionThe Mac ID (medium access control identification) of the master on the DeviceNet network.Valid range: 0 - 63. Default: 0.The starting address for an array of bits indicating the health of each node on theDeviceNet network. It must be a non-overlapping range in %AI, %I, %Q, %G, %AQ, %R,%T, or %M. It defaults to %I memory and uses the next available %I address.A slave's status address equals Start Address + Station Address of the slave. For example,if the status bits are mapped to %I00001, the status for the slave at Station Address 5would be found at %I00001 + 5 = %I00006.The master’s status is located in the same way as the slaves’ (Start Address + StationAddress). The master is configured as station 0 by default, but can be set to any validaddress (0-64).(Read-only.) Length has a value of 64, corresponding to 64 network devices.The starting address for three words of module/network status information. The default is%AI memory and uses the next available %AI address. The Network Status/Firmware IDAddress must be a non-overlapping range in %AI, %I, %Q, %G, %AQ, %R, %T, or %M.During system operation, the module and network status data and module firmware ID willbe stored in this memory location.(read only) Length of the Network Status / Firmware ID Address memory location, 3 words.When the PLC is in Program mode (Stop mode), the DeviceNet Master Module can eithersend idle packets or set data to zero. The default is to send idle packets.3-4 Series 90®-30 Programmable Controller DeviceNet Modules – November 2002 GFK-2196
