The ControlNet communication card links the FlexLogix controller and
PowerFlex 700S with DriveLogix controller to other devices on a ControlNet
network. The ControlNet communication card also provides access for the
FlexLogix controller to monitor and control I/O modules located remotely
from the controller on the ControlNet network. These cards support:
• I/O bridge functionality to manage distributed I/O modules.
• transfer of scheduled data via produced/consumed tags.

• unscheduled MSG instruction communication with other
ControlNet nodes.
• messaging data for configuration and programming information,
operator interfaces, upload/download.
• local communication network access through the NAP - not available
on the 1788-CNFR.
• redundant media (1788-CNCR and 1788-CNFR only).
• fiber media for optical isolation and increased noise immunity
(1788-CNF and 1788-CNFR only) used in conjunction with the
ControlNet short distance fiber repeaters.
• uses 200 micron cable (1786-FSxxx) with V-pin connectors and
1786-RPFS/RPA to connect to the network (1788-CNFR only).
The 1794-ACN15 and 1794-ACNR15 modules operate as adapters for FLEX
I/O modules on a ControlNet network. This module supports:
• control of I/O within its chassis–you can connect up to 8 FLEX I/O
modules to one 1794-ACN15 or 1794-ACNR15 module.
• unscheduled messaging data for configuration.
• local communication network access through the NAP.
• control of individual I/O modules by different controllers.

• redundant media (1794-ACNR15 only).
