4-2 Input, Output and Configuration Files for the Analog I/O Modules on the ControlNet Network
Use Programming Software
in Your FLEX I/O Application
When using FLEX I/O analog modules, you must perform I/O mapping and
configure the ControlNet network before generating configuration data for
your I/O modules.
For example, you may use RSNetWorx software to connect FLEX I/O
modules to a ControlNet processor or scanner through a FLEX I/O
ControlNet adapter (cat. no. 1794-ACNR15). The I/O configuration portion
of another programming software, for example RSLogix5 software, could be
used to generate the configuration data for each I/O module in the control
system.
Configuration data is transferred from the controller to the I/O modules
when communication to the modules is first established.
Follow these general guidelines when configuring I/O modules.
1. Perform I/O mapping.
2. Configure all I/O modules.
3. Change to Run mode to initiate communication.
4. Download module configuration.
About the ControlNet
Adapter
The FLEX I/O ControlNet adapter interfaces up to 8 FLEX I/O modules to
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.
