Optical link modules and AC 800M in a star topology
The following diagram shows PROFIBUS DP with a fiber optical link for bridging
long distances, for electrical isolation of parts of the system, or as a measure for
protecting against lightning.
A redundant line structure is shown, however it is possible to build this star topology
in a non redundant network.
