WIRELESS IO

Wireless gateways are used to connect wireless devices to the BPCS. Gateways should be logically distributed throughout the process unit like junction boxes. A gateway is usually localized to a process unit or area, and wireless devices are then assigned to the gateway based upon this logical assignment.

The first is the use of wireless instead of wired devices on the current project in all process areas due to factors such as lower installation costs, quicker installation time, faster commissioning, and more efficient change order management.
