Installing the Wiring Base and Power Supply

DeviceNet Connections

For network wiring, the wiring base has two DeviceNet terminal
blocks; one for incoming power and communications, the other for
outgoing power and communications. DeviceNet communications
requires 3 wires (2 communications, 1 ground) and a shield. You can
install the Reader in a single or multiple drop configuration. Up to 63
slave devices can be installed on a single DeviceNet master/slave
network. Up to 32 Readers can be installed on a DeviceNet
peer-to-peer network.
Reader
Both DeviceNet terminal blocks are tied to each other. You can
connect the wiring to either terminal block. Use cabling (Catalog
No. 1485C-P1A50, -P1A150 or -P1A300) for all DeviceNet
connections.
