4.2 Autoconfiguration or Programmer
Configuration
The configuration for a Genius NIU and I/O Station can either be
downloaded from the programming software or established by
autoconfiguration.
4.2.1 Autoconfiguration
Autoconfiguration is done by the NIU itself. It provides a default
configuration for the NIU and I/O Station and does not require the use of
a programmer. During autoconfiguration, the NIU determines which
modules are installed and automatically creates a configuration for the
I/O Station. I/O modules that have software-configurable features can
only use their default settings when the I/O Station is autoconfigured.
4.2.2 Programmer Configuration
Using the programming software makes it possible to reassign the
module’s I/O reference addresses, and configure many I/O module
features. The programming software runs on a computer that connects
to the NIU via the NIU expansion port.
The programming software can be used to:
•
Create a customized configuration
•
Download a configuration to the NIU
•
Upload an existing configuration from the NIU
•
Compare the configuration in the NIU with a configuration file stored
in the programmer.
•
Clear the configuration that is currently being used by the NIU and
force the NIU to autoconfigure.
The NIU retains its configuration across power cycles. Downloading a
configuration disables autoconfiguration, which means that the NIU will
not overwrite the downloaded configuration during subsequent power-
ups.
However, clearing the NIU’s configuration from the programmer does
cause a new autoconfiguration to be generated. In that case,
autoconfiguration is enabled for the next power-up unless a
configuration is subsequently downloaded using a programmer.
