necessary, a mild detergent.
3 System architecture
The versatility and flexibility of this valve system enables
AVENTICS to support your automation tasks. The valves are
completely assembled and tested according to your
requirements; the electrical connection is made via bus
couplers. The valve system in the local and external pilot control
versions is then ready for use. Its modular construction allows
existing systems to be expanded or converted at any time.
The valve system's operating instructions are composed
of individual components.

3.2 Function
This field bus connects simple sensors, frequency converters,
barcode readers, pneumatic blocks, etc. to a superordinate
system such as a PLC, PC or similar system.
DeviceNet is based on the CAN bus system and represents layer 7
in the ISO/OSI layer model. It is a linear bus system that uses a
twisted, shielded pair of wires as a field cable. The bus length can
be up to 500 m (without a repeater), depending on the transfer
rate. The bus coupler can be operated at a speed of 500 kBaud.
The baud rate is set via DIL switch S1 on the bus coupler. The node
address setting can be made via DIL switch S2. The logic supply is
protected by means of a diode against reverse polarisation. The
valve supply is protected against short circuits by a fuse.
The supply voltage is monitored before and after the fuse. If the
value falls below the set threshold, an error signal is generated
and the diagnostic information is reported via LEDs.

The baud rate, diagnostic mode and participant address
settings for DIL switches S1 and S2 are read after the L24V
power supply has been turned on (bus coupler power
turned on). The power must be turned on again for the
changes to take effect.
When delivered, all DIL switches are set to the OFF position.
DIL switch S1 is essentially for setting the baud rate.

See figure 2
4.1.2 Setting the bus coupler participant's address
An address (node) from 0 and 63 can be assigned. Double
assignments are not permitted within DeviceNet. A DIL switch is
active if it is at "ON". The individual switches S2/1 to S2/6 are
combined to form the node address. The bus coupler is
delivered with the bus address set at "0".
The set address is read by the bus coupler’s software after
the L24V supply voltage has been turned on. The bus coupler
supply voltage must therefore be turned off and then on
again in case of address changes.
Please note the order and position of the ON positions for
each individual switch. The switches are all at OFF at delivery.

NOTICEUndefined switching states
Connecting a mixture of actuators and sensors on one byte
(X1/X2 or X3/X4 or X5/X6 or X7/X8) is not permissible since it
could lead to undefined switching states. This applies
independent of the operating mode set.
O Leave or set the standard operating mode 0 when
operating the 32 I/O box on the DeviceNet.

Configuration In the interest of completeness, all possible settings are shown.
The 32 I/O box has 14 operating modes.
If operating mode 0 is selected, the number of input/output bits
or bytes actually required by the PLC can be set by assigning the
PLC addresses.
The standard configuration (32 input bits and 32 output bits,
outputs readable via inputs) always occupies 4 input bytes and
4 output bytes with respect to the PLC.
4.2 Valve system configuration
4.2.1 Electronic Data Sheet (EDS)
The Electronic Data Sheet EDS is an ASCII file specified by the
ODVA where DeviceNet's subjects/performance characteristics
are described. The file for the HF 03 valve system with the bus
coupler (corresponds to type RM65M-DN on the nameplate) is
called RM65MDN.EDS.
The diskette with the EDS file contains the files for all of the
valve system's components. The EDS file must be integrated in
the configuration tools to plan the valve system.
After that, this is done using the DeviceNet manager (from Allen-
Bradley). This makes a comfortable project solution available.
4.2.2 Configuration using the DeviceNet manager
(from Allen-Bradley)
Every valve system is fitted with valves and possibly input/
output modules, according to the contract, and must be
configured. In the following example this is done with help from
the "DeviceNet Manager" program. See the manual for more
details on dealing with this program.

O Start the DeviceNet Manager. It runs on a PC which is
connected to the DeviceNet via a serial interface with a
switching module. The serial interface must be configured
on the one hand and the switching module's node address
on the other hand in order for communication with the bus
to work.

5.2 Connecting the bus coupler electrically
5.2.1 Field bus connection
Sockets BUS X71 and BUS X72 for connecting the field bus cable
with the coupling plugs are located on the bus coupler.
If a continuing bus connection is needed, the “arriving” field bus
cable can be connected to BUS X71 and the “departing” one to
BUS X72 for example.
Since BUS X71 and BUS X72 are internally connected in parallel,
a T-junction is not required.

1. Detach the coupling socket with 22 and 24 mm open-ended
wrenches. On the cable, string together the cable part of the
socket (4), the sealing ring (3), the sealing and strain relief
element (2), and the metal disc (1).
2. Remove approx. 80 mm of the cable sheathing.
3. Spread out the wire braid. Wrap ground sleeve (5) over foil
or cotton braid and insert under wire braid with a turning
motion until wire braid and ground sleeve lie flat against
cable sheathing. Cut off wire braid flush with the outside of
the ring of the ground sleeve. Cut off foil, filler, and internal
cable insulation so that the wires lie free. Remove about
3 mm insulation from the wires, twist together, and apply
solder to each wire.
4. Run the wires through the corner piece (6) until the ground
sleeve lies against the corner piece.
5. Solder the cable wires to the pins on the contact body (7) (for
assignment see Table 5). Wrap the spacer sleeve (8) around
the wires. Insert the contact body and spacer sleeve into the
front piece (9) of the cable socket. When doing this, mate the
coded groove of the contact body (7) with the coded ridge.
Insert the whole unit (7), (8) and (9) into the corner piece so
that the cable exists in a satisfactory direction. In doing this,
the front piece can be mounted in the corner piece in any of
8 positions, spaced 45° apart.
Secure with nut (9a).
Push the metal disk (1) and sealing ring (3) with the sealing
and strain relief element (2) into the corner piece and secure
the cable part (4) of the coupling socket.

5.2.2 Connecting the bus coupler logic
5.2.3 and load supply
POWER X10 The following are powered via the plug POWER X10 (bus coupler):
– the valves,
– the bus coupler,
– all input modules and the output modules that are aligned
on the bus coupler,
– but not the 32 I/O box.
See section 9 The bus coupler operating voltages must be connected via the
coupling socket (Accessories) in accordance with Table 12.
See section 8 The operating voltages given in the electrical data
characteristics must be adhered to.

The following current levels must be provided. The cable cross-
sections must be selected according to the cable length and the
operating current:

power consumption
(bus coupler)
CAUTIONThere is an internal connection between the PGND pin on the
X10 and the PGND pin on the bus coupler's X10 if a power
module is present. That means: if a power supply unit without
safe isolation is used and the power supply is only connected
to one of the two X10 plugs, voltage can form on the PGND pin
which is dangerous when touched.
O This measure is therefore absolutely required:
The 24 V power supply must stem from a power supply
unit which is electrically isolated according to
DIN EN 60742, classification VDE 0551.
