Functional Exclusions

The SST-PFBCLX does not currently support the acyclic services
associated with the PROFIBUS DP-V1 extension.

Topology

The diagram below depicts an example of the intended
ProcessLogix/PROFIBUS interface in a typical hardware topology:

Figure 10.1 ProcessLogix/PROFIBUS Topology

ProcessLogix/PROFIBUS Topology Descriptions

The SST-PFBCLX is the DPM1 (DP Master Class 1 device).

Although ControlNet is depicted for the supervisory network,
Ethernet supervisory networks are also possible.

A redundant controller configuration is depicted. Non-redundant
configurations are also permitted, thus allowing the SST-PFBCLX
to reside in the controller chassis.

PROFIBUS DP supports both stand-alone and modular I/O
devices. Although only one SST-PFBCLX is depicted, one
1757-PLX52 controller can host multiple PBIM’s.
