Opto 22 has added wireless LAN capability to these controllers and
brains without removing the communication functions that are
already there.
Wired and Wireless Support
A SNAP PAC controller, for example, has two independent Ethernet
interfaces (two IP addresses; two network interface cards, or NICs).
These two interfaces can be used for redundant links or for
segmenting networks. Adding wireless support means that the PAC
now has three Ethernet interfaces (three IP addresses; three NICs)—
two wired and one wireless. If desired, the wireless controller can
segment a wired from a wireless network and provide a redundant
link as well.
A SNAP PAC brain, in contrast, has two switched Ethernet interfaces
(one IP address; one NIC). The switched interfaces allow these
intelligent I/O processors to be daisy chained, if needed. Adding
wireless support to the brain means adding a second IP address, so the
brain can communicate through either a wired or wireless network, as
required by the application.
These controllers and brains retain the same functions whether they
are used wired or wirelessly.
All the standard industrial protocols supported by the wired Ethernet
interface are fully supported over wireless. These protocols include
ODVA’s EtherNet/IP™, Modbus®/TCP, OptoMMP, SNMP, SMTP, and FTP.
brains). These controllers and brains also handle all
communications for the system.
The same brains, or intelligent I/O processors, provide both local
processing and communications for SNAP I/O used with A-B and
PC-based systems.

Wireless PACs and I/O in Industrial Automation
In addition, the same control and HMI development software is used
regardless of physical network. Because the physical layer is
abstracted, control programs running on the PAC require no
modification for wireless communication.
Communications for both wired and wireless networks are set up in
the same configuration software and can be done at the same time, or
one network type can be added later.
Full I/O Product Line
Because Opto 22 adds wireless capability by modifying only its
controllers and brains, the company offers the same I/O modules,
racks, and other components whether the application is wired or
wireless. No additional wireless components are needed.
The full line of analog, digital, and serial SNAP I/O modules is available
for engineers to use with either network—an important point, since
the company is well known for the breadth and reliability of its I/O.
Existing Opto 22 customers will also find it easy to experiment with or
switch to wireless: they can simply exchange the existing brain or
rack-mounted controller with a wired/wireless one. The mounting
rack, I/O modules, field wiring, and all other communication and
processing functions remain intact.
