Fiber-Optic Cabling-Based Media Redundancy; Redundant Pgm In A Non-Redundant Profibus Cabling - Honeywell Experion PKS User Manual

4 PROFIBUS GATEWAY MODULE (PGM) INSTALLATION

4.6.2 Fiber-optic cabling-based media redundancy

The following diagram illustrates the fiber-optic cabling-based media redundancy. In this topology, the
redundant backbone is the optical cable based redundant ring where redundant or non-redundant segment are
connected through OLM modules.
Attention
Terminators are very important for copper segments. All Copper segments must use external terminator units.

4.6.3 Redundant PGM in a non-redundant Profibus cabling

The following diagram illustrates a topology of a redundant PGM in a non-redundant Profibus cabling scenario.
