1.3 Survey of Advant Fieldbus (AF100),
07 KP 95 and ABB Procontic CS31
– The AF100 is a field bus, to which a maximum of 80
AF100 stations (nodes) can be connected. Each sta-
tion can be a master or a slave. At least one master
must be connected to an AF100, several masters are
possible.
– The AF100 distinguishes between process data,
which are transmitted cyclically (Cyclic Data Pack-
ages) and messages (diagnosis data, events), which
are only transmitted if necessary.
– The AF100 can be configured in single–channel
mode or redundant. In the redundant configuration,
the data are always sent via both busses. The data,
however, are only received from one bus. The
switch–over to the bus, from which the data is re-
ceived, is performed automatically by the hardware.
– The transmission medium for the AF100 can be a
twisted pair, a coaxial cable or an optical fiber. For the
connection between the coupler and the AF100 bus,
an appropriate modem must be selected.
– For the transmission of cyclic data on the Advant
Controller side, the data base element DSP (Data Set
Peripheral) is available. Each DSP can contain up to
8 data elements (DATs) of the types boolean, integer,
long integer or real. In the data base element, the fol-
lowing is given: the number of DATs, the transmission
interval, the direction (sending or receiving DSP), the
identification and the station number.
– Analog to that, on the CS31 side there are the func-
tion blocks DSPIN (receiving DSP) and DSPOUT
(sending DSP). As a maximum, a number of 475
DSPs with 8 DATs each can be configured. The max.
number of function blocks is 250 DSPINs and 249
DSPOUTs.
– For initialization, the function block AF100 is avail-
able (station number, master/slave, AF100 bus
single/redundant).

1.5.1 Application examples for AF100
coupling with modem, coupler 07 KP 95
and central unit
The following figures show two application examples for
single–channel and redundant configuration. Attention
must be paid to the following in detail:
● The earthing measures
● The connection of the communication processor
07 KP 95 to the modem(s).
● Looping through the supply voltage (24 V DC) from
the 07 KT 93 to the 07 KP 95 R101
● Earthing the switch cabinet mains sockets
● Using the AF100 bus with coaxial cable
