Figure 3-58 to Figure 3-61 show the routing for a communication topology of protection interface type 1.
To transmit signals to other devices, these signals must be routed in the communication matrix under
Transmit. Binary inputs 1 and 2 are single-point indications (SPS) and are routed to position 1 and position 2
of the transmission with the highest priority (priority 1). For 64 kbit/s, for example, only 8 of these data areas
are available for type 1; they are exchanged between the transmission routes with each telegram. Signals 3
and 4 are double-point indications (DPS), for example, a switch position that is transmitted by a device 1. A
double-point indication occupies 2 positions on the data bar. In addition, a measured and metered value are
communicated via priority 3.
As a measured or metered value uses 32 bits, value 2 starts at position 33. DIGSI 5 indicates the next available
position.
