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
