Architecture
When operating with a Stahl CPM 9440 Remote I/O, the component architecture might be
as for example as shown in Fig. 4.4. The Fieldgate SFG500 is connected to the Ethernet
backbone via the LAN 1 Ethernet socket. PROFIBUS PA devices are connected to the network
via e.g. a transparent coupler. The 4–20 mA/HART devices are connected point-to-point to
the Stahl Remote I/O, which in turn is connected to the PROFIBUS DP segment.

To see all the devices on the PROFIBUS DP/PA segment, FieldCare requires:
• SFGNetwork DTM
• Licensed Stahl CommDTM CPM 9440
• All PROFIBUS Device DTMs
• All HART Device DTMs
