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.

2 sockets

Connections for the field bus DeviceNet, for control of valves and

I/O modules.

POWER X10 plug Electrical connection for

W valve solenoids and outputs,

W logic and

W inputs.

Control elements Two 8-position DIL switches for setting the node address, baud rate

and various modes of operation using the PG screw cap S1/S2.

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.

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.

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.

Configuration


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.

O Then the participants connected to the bus are searched for

using the Who menu item. The following participants are

connected in the example described here:

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.

Assembly of the bus

connection plugs

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.
