Preface
1788-CN2PAR Linking Device and ControlNet Network
The diagram shows an example of how a 1788-CN2PAR linking device can 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) and eight output PVs.
The linking device uses four controller connections. Data for the 24 field devices
is distributed over the four common industrial protocol (CIP) connections.
Connection A has the data for the linking device and four field devices.
Connections B, C, and D have the data for 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 general status
description (GSD) files. The utility is launched from the AOP in the Studio
5000 Logix Designer application or directly in Microsoft Windows.
Field Device Tool/Device Type Manager (FDT/DTM) technology is supported;
this technology 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.
