Ethernet Communication
All SNAP PAC R-series controllers communicate over standard
10/100 Mbps Ethernet networks and can be attached to an
existing network. The controllers can also be used in an
independent control network built with standard, off-the-
shelf Ethernet hardware.
SNAP PAC R-series controllers include two 10/100 Mbps
Ethernet interfaces for networking to Ethernet hosts and to
other I/O units. These independent Ethernet ports have
separate IP addresses that can be used with PAC Project
Professional software to set up redundant network links to
safeguard the availability and reliability of an I/O system, or to
segment a control system’s network from the enterprise LAN.
Supported protocols over Ethernet include EtherNet
Modbus
Wired+Wireless Communication
SNAP-PAC-R1-W and SNAP-PAC-R2-W controllers add
wireless capability to communications. In addition to the two
wired network interfaces, these models have a wireless
network interface as well, so each PAC has a total of three
separate IP addresses—two wired and one wireless.
Wired+Wireless PACs can be used wirelessly or on a
wired network, or both at once.
For flexibility in designing your wireless network,
wireless communication includes support for 802.11a,
b, and g standards. Wired+Wireless PACs can be used
with a variety of wireless switches and other
infrastructure hardware. For the best security, the
802.11i WPA2/AES standard is supported, while older
WPA and WEP security standards are included for
backwards compatibility.
Because wireless functionality is in the PAC itself, no
additional parts are required within the
control system for wireless use. All
SNAP PAC racks and SNAP I/O modules
can be used either wired or wirelessly.
You can switch from one network to
the other without reconfiguring I/O or
changing field wiring.
Just like a laptop computer with a
wireless connection, all functionality
remains the same whether the
Wired+Wireless PAC is used wirelessly or
as part of a wired network. Supported
protocols remain the same. And control

programs run the same on both networks without
reprogramming.
Serial Communication
SNAP PAC R-series controllers provide an RS-232 serial link to
support Point-to-Point Protocol (PPP) modem connections—
for creating TCP/IP networks over serial or PSTN (Public
Switched Telephone Network) lines—as well as remote serial
device communication.
The RS-232 serial interface supports either a modem
connection using PPP or general-purpose communication
with serial devices, allowing you to send and receive data from
a serial device connected directly to the controller. For
additional serial interfaces, you can add one or more SNAP
serial communication modules on the rack.
NOTE: The R-series controller does not include an RS-485 port and
cannot be used to control Opto 22 serial I/O processors, such as the
SNAP PAC SB-series brains. Use an S-series controller for serial
brains.
I/O Mounting Racks
SNAP PAC R-series controllers must be connected to the
appropriate rack to avoid damage to the controller. Both
the SNAP-PAC-R1 and R2 are designed to work with SNAP
PAC mounting racks, which are available with 4, 8, 12, or 16
positions for Opto 22 SNAP I/O modules. Part numbers are
SNAP-PAC-RCK4, SNAP-PAC-RCK8, SNAP-PAC-RCK12, and
SNAP-PAC-RCK16. Factory Mutual-approved versions of
these racks, with part numbers ending in -FM, are also
available.
