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

1The DeviceNet NetworkDeviceNet is a communications network that transmits data between control systems (for example:PLCs, PCs, VMEbus computers, and robot controllers) and distributed industrial devices such asswitches, sensors, valve manifolds, motor starters, bar code readers, drives, displays, and operatorinterfaces. The network can also link intelligent interface modules such as the VersaPointDeviceNet Network Interface Unit (NIU) and the VersaMax DeviceNet NIU. An NIU is thenetwork interface for an I/O Station of many additional modules.The DeviceNet network has a linear structure. There is a main trunk line with drop lines routed tothe networked devices. Power and signals are carried on the same network cable. A Series 90-30DeviceNet module can be connected directly to the trunk cable or installed as an individual drop oras part of a daisy-chain drop.MasterSeries 90-30 PLC withDeviceNet Master ModuleSlavesSeries 90-30 PLCwith DeviceNet SlaveModuleGFK-2196 Chapter 1 DeviceNet Modules for the Series 90-30 PLC 1-7
