SNAP PAC programmable automation controllers (PACs) and industrial I/O processors (brains) offer several networking options to meet the needs of your application, whether it be in industrial automation, remote monitoring, data acquisition, process control, discrete manufacturing, energy monitoring, or SCADA.

These flexible networking options are possible because each SNAP PAC controller or brain has two Ethernet network interfaces.

SNAP PAC controllers—both standalone and rack-mounted—have two independent network interfaces with separate IP addresses. These controllers can segment the control network from your company's computer network or accommodate redundant Ethernet links.

SNAP PAC Wired+Wireless™ controllers add a third independent Ethernet interface: a wireless one. You could use a wireless LAN for energy monitoring, for example, and segment it from the rest of your industrial control system.

SNAP PAC S-series controllers can also be used for controller redundancy. Redundancy requires two identical S-series PACs, PAC Project Professional 9.0 or newer, and the Redundancy Option Kit.

SNAP PAC Ethernet-based brains (industrial I/O processors) have two switched Ethernet network interfaces that share the same IP address. Because they're switched, you can daisy-chain your distributed I/O. Wired+Wireless brains add an independent wireless LAN interface as well.

For more on networking options, see Chapter 3 in the SNAP PAC System Specification Guide.
