PROFIBUS
S800 I/O and a communication interface module can be directly connected to
PROFIBUS-DP or PROFIBUS-DPV1 network.
When connected to PROFIBUS, the communication interface module and its S800
I/O modules are called a S800 I/O station.
An S800 I/O station works as a slave on PROFIBUS.
ModuleBus
A Fieldbus Communication Interface module communicates with its S800 I/O
modules over the ModuleBus. It communicates internally in the base cluster and
externally with other additional clusters within the same S800 I/O station by using
Optical ModuleBus Modems TB820, TB840 or TB840A. The Optical ModuleBus
Modems are connected via optical cables to a ModuleBus Optical port module on
the communication interface module.
