Input, Status, Output and Configuration Files
using ControlNet
What this Chapter Contains
Read this chapter to familiarize yourself with input, output and
configuration files for analog I/O modules on ControlNet.This chapter talks
about:
• the ControlNet Adapter
• I/O structure
• fault state data
• communication fault data
• idle state behavior
• input data behavior upon module removal
About the ControlNet Adapter
The FLEX I/O ControlNet adapter (cat. no. 1794-ACN15 or -ACNR15)
interfaces up to 8 FLEX I/O and/or FLEX Integra modules and a
ControlNet processor or scanner. The adapter can support ControlNet
real-time data connections to individual modules or module groups. Each
connection is independent of the others and can be from different processors
or scanners.
Communication Over the
FLEX I/O Backplane
One ControlNet adapter can interface up to eight terminal base units with
installed FLEX I/O and/or FLEX Integra modules, forming a
FLEX I/O system of up to eight slots. The adapter communicates to other
network system components (typically one or more controllers or scanners,
and/or programming terminals) over the ControlNet network. The adapter
communicates with its I/O modules over the flexbus backplane.
