SNAP IO4AB Learning Center
Description
The SNAP IO4AB Learning Center delivers a complete package for
learning to configure and use implicit messaging via EtherNet/IP
between an Allen-Bradley Logix controller and Opto 22’s intelligent
remote SNAP I/O
Not just a sample, the SNAP IO4AB Learning Center includes the
field-proven, real hardware and software used by Opto 22
customers all over the world.
With the SNAP IO4AB Learning Center and EtherNet/IP Configurator
you can explore the following:

After you’ve explored their capabilities, you can continue to use the
same hardware and software to take advantage of Opto 22’s
distributed intelligence in your own application. With distributed
intelligence, a controller (such as an Allen-Bradley PLC), handles
overall control but certain functionality can be configured and run
at the I/O level, thus reducing logic programming as well as CPU
scan time. The I/O’s own onboard processor (called a brain) has the
intelligence to handle a wide range of functions, which reduces the
load on the controller. Since these functions run locally on the I/O
unit, they continue to run even if communication to the controller
is lost.
While other manufacturer’s devices may report only states and
counts, our intelligent remote I/O can provide sophisticated
