Modern Automation networks have standardised on Ethernet and the Internet 'IP' protocol across the Local Area (Plant Wide) Network (LAN).
Interconnection of sites generally requires the use of public Wide Area Network (WAN) services (ADSL/FTTC/3G4G). The WAN router provides the interconnect between LAN and WAN.
These devices can be quite complex and their performance and features vary considerably as do their price.
Characteristics that impact cost include:
- Environmental robustness
- Routing protocols
- Encryption / VPN
