Wired and Wireless Networks
The network shown in this diagram requires a Wired+Wireless S-series controller (SNAP-PAC-S1-W
or SNAP-PAC-S2-W). The PAC runs a PAC Control strategy and controls remote I/O units via a wireless
access point. The controller is also connected to a separate, wired enterprise network through one of
its wired Ethernet network interfaces.
The controller could just as easily talk to the I/O units through a wired network and segment the
enterprise PCs on a wireless LAN. In addition, because the Wired+Wireless PAC has two wired
interfaces plus the wireless one, it could segment three networks—for example, a wired control
network, a wired enterprise network, and a wireless connection with a laptop for maintenance or
testing purposes.
