907 KP 95 / Issued: 09.97
Specification in accordance with Item 5.2 ALCN
____________________________________________________________________________________________
General
The programming of the communication processor is car-
ried out in the PLC program with a PC using the program-
ming and test system 907 PC 331.
The programming software 907 KP 95 provides all con-
nection elements necessary for operating the commu-
nication processor 07 KP 95:
● AF100
● DSPIN
● DSPOUT
● DWREAL
● REALDW
The communication processor 07 KP 95 allows interfac-
ing of ABB Procontic CS31 to the AF100 (Advant Field-
bus 100). The communication processor 07 KP 95 needs
additionally a communication interface CI520 and an ap-
propriate bus modem. The 07 KP 95 contains the carrier
board for the CI520 (similar to the Submodule Carrier
Board with the Advant Controller 450, but the 07 KP 95
has only one slot for one CI520).
Features of the unit 07 KP 95
The following functions are supported by the 07 KP 95:
– master or slave at the AF100 (function block AF100)
– single-channel or redundant configuration of the
AF100 (selectable via the function block AF100)
– transmission of cyclic data using the function blocks
DSPIN and DSPOUT (max. 475 DSPs with 8 DATs,
max. 250 DSPIN and 249 DSPOUT)
– service data: station, type, version, status
– no event handling
– no time-sync
– no program-load
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).
