ControlNet-to-Foundation Fieldbus H1 Linking 
Device
Catalog 1788-CN2FF
Product Overview
The ControlNet-to-Foundation Fieldbus H1 linking device (1788-CN2FF) connects a 
ControlNet™ network with one or two F
OUNDATION
Fieldbus H1 (Fieldbus) networks.
Each H1 network consists of multiple Fieldbus devices. Each field device has one or more 
function blocks. Each function block performs an elementary control function such as analog 
input, analog output, discrete input, or discrete output. The ControlNet network consists of 
controllers, such as PLC
®
processors, HMIs, drives, I/O devices, and so on. The
1788-CN2FF has three broad functions, supporting the following:
• closed-loop control
• configuration
• a redundant ControlNet network design
ATTENTION
The 1788-CN2FF module ships from the factory with 
configuration switches set to “ON (RESET)”. With switches 
“ON”, any configuration data would be reset on Power 
interruption. Set the switches to “OFF (NORMAL)” after initial 
power-up (to clean any Factory test configurations) but before you 
configure the module with your application. 
Remove power to the module before resetting configuration 
switches. For more information on configuration refer 
to Configuring the 1788-CN2FF Linking Device on page 9.
