CompoBus/D Network
H Multi-vendor Network
The CompoBus/D conforms to the DeviceNet open field network specification, which means that de-
vices (Masters and Slaves) produced by other manufacturers can also be connected to the Network.
Therefore, a wide range of field-level applications can be supported by combining valve devices, sen-
sors, and other devices.
H Simultaneous Remote I/O and Message Services
Remote I/O communications to constantly exchange I/O data between the PC and Slaves can be
executed simultaneously with message communications, to send/receive Master Unit data as required
by the application. Therefore, a CompoBus/D Network can be installed to flexibly handle applications
that require both bit data and message data. Message communications can be achieved either by using
OMRON’s FINS commands or by using DeviceNet explicit messages.
H Connect Multiple PCs to the Same Network
A Configurator (sold separately) can be used to enable connection of more than one Master to the Net-
work, allowing message communications between PCs and between multiple groups of PCs and
Slaves. This allows the CompoBus/D Network to be used as a common bus to unify controls while re-
ducing wiring.
H Handle Multi-point Control and Line Expansions with Multi-layer
Networks
A Configurator (sold separately) can be used to enable mounting more than one Master Unit to a single
PC, allowing control of many more points. This feature can easily handle line expansions and other ap-
plications.
