PSI-MOS-PROFIB/FO... 7.4 Idle setting During the idle phase, fiber optic interfaces return to an idle setting defined by the manufacturer. This idle setting may vary for different manufacturers and devices. As fiber optic interfaces can only be operated to- gether if they have the same idle setting, this should be ob- served in mixed operation with third-party devices (see "Connection to fiber optic interfaces from third-party suppli- ers (DIP switch 5/6)" on page15). For PSI-MOS, the idle setting is specified as "Light on" (cor- responds to "Logic 1"). When connecting third-party devices, observe the receiver sensitivity and overrange limits of the fiber optic interfaces. 7.5 Interfaces The devices have three or four interfaces for the PROFIBUS signal: – Electrical interface (D-SUB) – DIN rail connector – FO port A – Fiber optics port B (only with T-couplers PSI-MOS-PROFIB/FO...T) All interfaces communicate with one another with the same rights. If a signal is present at one of the interfaces, this sig- nal is also available to all other interfaces.
