DeviceNet Unit Features Section 1-2
Multiple PCs in a Single
Network
Multiple DeviceNet Units can be connected in a single network for message
communications between PCs as well as for remote I/O communications
between PCs and slaves in multiple groups. This feature allows a DeviceNet
to be used as a common bus that can integrate all types of control with less
wiring.
Note Refer to 4-1 Master Remote I/O Communications for details.
Multiple DeviceNet Units
on a Single PC
Up to 16 CS/CJ-series DeviceNet Units can be mounted to a single PC. This
feature enables greater DeviceNet remote I/O control capacity and ensures
that DeviceNet can easily handle line expansion as well as other applications.
Note 1. Multiple Units can be mounted without the Configurator.
2. DeviceNet Units set as both slaves and/or masters can be mounted at the
same time.
3. Refer to 4-1 Master Remote I/O Communications for details.
DeviceNet Unit Setup Files
(Memory Card Backup)
Setup data (e.g., scan lists) in a DeviceNet Unit can be written as a file to the
Memory Card mounted in a CPU Unit. This feature greatly simplifies
DeviceNet Unit replacement. A DeviceNet Unit device parameter file (same as
data setup file) that is prepared offline using the Configurator can be saved on
a Memory Card, and setup data from the Memory Card can be downloaded to
