6. Features
6.1 Profibus interface
The connection of the IF09P to the Profibus
is via a 9 pin DSUB connector according to
EN 50170. If a bus must be terminated this
must be done in the connector, i. e. appropria-
te connectors with terminators that can be
switched in should be used. The following bit
rates are supported: 9.6kBit/s, 19.2kBit/s,
93.75kBit/s, 187.5kBit/s, 500kBit/s, 1.5MBit/
s, 3MBit/s, 6MBit/s und 12Mbit/s. Further
profibus-specific parameters are included in
the corresponding device database file
SIKO00EC.GSD which is available on re-
quest or may be downloaded from the inter-
net location http://www.siko.de/download
6.2 Interface to AP09 or SIKONETZ3
(connection Sensor "Geber")
The hardware interface to the sensors (AP09 or
SIKONETZ3 devices, resp.) is mounted on a 9
pin DSUB connector and is based on the RS485
standard. The baud rate of the AP09 protocol is
115.2kbit/s, and 19.2kbit/s with the SIKONETZ3
protocol. The connected sensors can be powe-
red via two additional pins.
The connection current must not exceed 1A !
6.3 Function
During the data exchange phase, the IF09P polls
the positional values from the connected sen-
sors. These are made available to the master
station (e. g. Siemens S7) via Profibus protocol
chip SPC3.
Furthermore, there is the possibility to parame-
trize the connected sensors via specific com-
mands in the Master-SPS, to conduct status
queries or have executed system commands.
Further below you will find a description of the
data telegrams and of the command table.
Fault conditions such as wrong parameters,
wrong station addresses or communication er-
rors are identified by the IF09Pand communica-
ted to the master SPS through error codes in the
data telegram.
6.3.1
Start phase
If all devices, IF09P and the sensors (AP09 or
SIKONETZ3 stations, respectively) are turned
on at the same time, the following switch-on
sequence will run.
• The SIKONETZ stations are initialized.
• The IF09P is initialized as well and waits
approx. 2,5 s until the sensors are initialized.
• Now, the IF09P identifies the number of con-
nected sensors.
IMPORTANT NOTE:
The sensors must be set
in ascending address sequence, starting with
address 1! There must be no address "gaps"!
The respective user manuals will inform you on
how to set the addresses of the sensors.
6.3.2
Operation phase
• After identifying the number of connected
sensors, the PROFIBUS interface is intial-ized.
Afterwards, the position values of the sensors
are requested from the sensors in a program loop
and made available to the Profibus interface.
6.3.3
Parameterization phase
• When the master SPS sends an parameteri-
zation request to the IF09P, the query of the
position value is suppressed until the paramete-
rization request has been processed. The pro-
