Fig. 2: Bus structure with PSS SB ACTIVE JUNCTION BASIS (principle)

The Active Junction is one of the

non-safety-related

devices on SafetyBUS p. It

is not assigned a Device Address. Although the Active Junction is not registered
as a bus subscriber, it must be regarded as a bus subscriber when establishing
the transmission rate.

If there is a short circuit in the supply voltage to a sub branch near to the Active
Junction (up to ca. 10 m cable runs), the supply voltage to the sub branch will be
switched off. The “Supply” LED for the relevant sub branch will turn red (see
sections entitled “Display elements” and “Faults”).

If a signal error occurs within a sub branch (permanent dominant signal level),
the sub branch will be ignored. The “Traffic” LED for the relevant sub branch will
turn red (see sections entitled “Display elements” and “Faults”).
