Functions and System Configuration
■ Connect Multiple PLCs to the Same Network
A Configurator (sold separately) can be used to enable connection of more than one Master to the
Network, allowing message communications between PLCs and between multiple groups of PLCs
and Slaves. This allows the DeviceNet Network to be used as a common bus to unify controls while
reducing wiring.
■ Handle Multi-point Control and Line Expansions with Multi-layer
Networks
A Configurator (sold separately) can be used to enable mounting more than one DeviceNet (Master)
Unit to a single PLC, allowing control of many more points. This feature can easily handle line expan-
sions and other applications.
■ Free Remote I/O Allocation
A Configurator (sold separately) can be used to enable flexible allocation of I/O, i.e., in any area and
in any order. This allows I/O allocations that suit the application to simplify programming and enable
effective usage of PLC memory areas.
■ Handle Slaves with Different Response Speeds
A Configurator (sold separately) can be used to set the communications cycle time, enabling usage
of Slaves with slow response times.
■ Easily Expand or Change Lines with Various Connection Methods
Use a multi-drop trunk line, T-branch multi-drop lines, or daisy-chain drop lines. All three connection
methods can be combined to flexibly construct a Network that meets the needs of the application.
Note For connecting the DeviceNet Communications Unit of the Inverter, use DCA1-5C10 Thin
Cables and branch them from the T-branch Tap.
