Preface
1788-CN2FFR ControlNet Network
This diagram shows an example of how a 1788-EN2FFR linking device could be
used with a ControlNet network.
Features The AOP provides an intuitive graphical interface to configure devices. A
predefined data structure for each field device provides eight input process
variables (PVs), eight output PVs, and eight PVs for inter-device communication
for full distributed control.
The linking device uses four controller connections. The data for the 16 field
devices is distributed over the four CIP connections. Connection A has the data
for the linking device and four field devices. Connection B, C, and D have the
data of four field devices each. The minimum requested packet interval (RPI) is
100 ms, and the maximum is 3,000 ms.
The HSProcessUtility is used to manage and register the field device description
(DD) files. The utility is launched from the AOP in the Studio 5000 Logix
Designer application, or directly in the Microsoft Windows operating system.
Field Device Tool/Device Type Manager (FDT/DTM) technology is supported.
This allows access to field device configuration and diagnostics via FDT Frames
such as FactoryTalk® AssetCentre. In addition, the Rockwell Automation FDT
ThinFrame (read only) can be launched from a FactoryTalk View or via the AOP
providing access to each field devices status and extended diagnostics.
