The DeviceNet Communications Unit's communications connector connects to the Master Unit through a DeviceNet communications cable. Up to 64 Slice I/O Units can be connected to one DeviceNet Communications Unit. DeviceNet Master DeviceNet Communications Unit Slide Slice I/O Units in from the front to install. 24 VDC for Unit 24 VDC for I/O Slice I/O Units (64 max. ) Note (1) Do not connect or disconnect the DeviceNet Communications Unit's communications cable while the DeviceNet network is operating. Short-circuits or poor contacts in the DeviceNet cable may prevent normal communications. (2) Be sure that the power supplies for the DeviceNet Communications Unit, Slice I/O Units connected to the DeviceNet Communications Unit, and external I/O are wired correctly through the DeviceNet Communications Unit's terminal block. 3-1-1 Connecting the DeviceNet Communications Unit and Slice I/O Unit Connect the first Slice I/O Unit to the DeviceNet Communications Unit by aligning the sides of the Units and sliding in the Slice I/O Unit from the front. Additional Slice I/O Units can be connected consecutively to the first. Slide the Slice I/O Unit toward the DIN Track from the front. Insert the Unit until you hear a click, which indicates that the Unit has locked on the Track. It is not normally necessary to release the DIN Track mounting hook when mounting the Unit. Note Do not touch the connector on the Unit's base block. 40 Installation Section 3-1 3-1-2 Connecting Additional Slice I/O Units Connect additional Slice I/O Units by aligning the sides of the Units and sliding in the next Unit from the front. [. . . ] Standardizes the configuration and behavior (the smallest data configuration and operation that must be supported by the devices) of devices of the same type. Provides mutual exchangeability between devices of the same type. Devices for which device profiles are currently being studied include sensors, valves, display units, and encoders. A node can be either a master, which collects and distributes data, or a slave, which outputs and inputs data according to the instructions received from the master. [. . . ]
