Multi-vendor Network
■
The DeviceNet conforms to the DeviceNet open field network specification, which means that
devices (Masters and Slaves) produced by other manufacturers can also be connected to the Net-
work. Therefore, a wide range of field-level applications can be supported by combining valve
devices, sensors, and other devices.

Simultaneous Remote I/O and Message Services

■
Remote I/O communications to constantly exchange I/O data between the PLC and Slaves can be
executed simultaneously with message communications, to send/receive DeviceNet (Master) Unit
data as required by the application. Therefore, a DeviceNet Network can be installed to flexibly han-
dle 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.
