315-WH-GT WirelessHART Gateway
WirelessHART‑compliant infrastructure gateway for wireless sensor networks
Description
The 315-WH-GT WirelessHART™ Gateway establishes
the connection between wireless field instrumentation
and asset management or distributed control systems.
Serving as the central controller and security manager
for low‑power wireless mesh field instruments
operating under the WirelessHART standard, the
315‑WH‑GT ensures performance through dynamic
network optimization and intelligent routing to achieve
high reliability, lower latency, and deterministic power
management. The embedded security manager
protects the plant network through secure device
authentication, end-to-end encryption and message
integrity checking to create one of the most secure
wireless mesh networks available.
Operating with a low‑power WirelessHART 802.15.4
RF link to the sensors, connectivity to the host system
can be provided either via hardwired LAN connection
or secure wireless LAN (802.11b/g or 802.11a). The
315‑WH-GT Gateway can also be coupled with the
315‑WH-DC WirelessHART Data Concentrator to
create a high performance wireless backbone that
offers reliable and secure connectivity from multiple
WirelessHART sensor networks, as well as allowing
secure, non-disruptive expansion of the network as
needed.
