Overview of DeviceNet Section 1-1
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 reduc-
ing wiring.
Multiple Master Units
Handle Multi-point Control
and Line Expansions
A Configurator (sold separately) can be used to enable mounting more than
one Master Unit to a single PLC, allowing control of many more points. This
feature can easily handle line expansions and other applications.
