Figure 3-62 Routing of Single-Point Indications to be Sent to the Protection Interface in Device 2
The binary outputs 1 and 2 (Receive) in the 2nd device are connected to priority 1 signals 1 and 2 from the
1st device. This takes place via the data areas at positions 1 and 2 of the data bar, which transfer the state of
the indications. Other devices can also read this information and link it to their internal signals. Here, too, the
secure state, which is assumed when the protection connection is interrupted, is entered. This state depends
on the information. In the case of single-point indications, the state is 0 or 1. In the case of double-point indi-
cations, the bit combinations 00, 01, 10, or 11 are possible, in order to directly signal a disturbed position
upon failure of the data connection, for example.
Hold is used to retain the state.
