The wireless gateway 1420 from Emerson Automation Solutions can support up to 100 devices. However, knowing the update rate is important to scale out the number of devices it can support at once.

That’s not to say there aren’t a maybe a few applications where you need a different protocol… But in general, it’s no big deal. Going deeper in 1420, all configuration can be done using the web server already integrated into the gateway.
The new design of the web server creates a valuable user experience. You can easily navigate the menus without the needing to have a special software to setup the wireless network.
Although, if you want to access the field device remote, there is an extra step. You need to have a Plant Asset Management System. This is where you can set up, see Diagnostic and more from your field devices in general.
In general, the smart wireless gateway 1420 brings good protocols and features for your daily use. However, if you don’t need approvals and an external install you can use the wireless gateway model 1410.
