Emerson / Siemens Gateway

Pros

Mature solution (early market entry)

Highly functionable

Good network diagnosis

Cons

Especially designed to fit in AMS/DeltaV

Some operating modes not optimized

No DTM available

Proprietary connection to AMS

Unclear and confusing web Interface

Floods network with unnecessary communication -> shorter battery life!

Phoenix Contact Gateway

Pros

Compact solution

Provides a WLAN as the network backbone

Good instrument list overview

Cons

No outdoor use

must be mounted in an additional enclosure as shown)

No DTM

Stahl / E-Senza Gateway

Pros

Cons

Network manager must run on a seperate PC

No industrialized solution

Stahl solution uses a FieldBarrier housing

Uses E-Senza as Supplier – unclear

compatibility

Must be mounted in a separate

enclosure

Stahl

E-Senza
