5.10.1
Network options
Parameters for identifying the reading devices in the network are combined in the
5.10.1.1
Device ID
parameter assigns the device a unique number in the network. The assigned
ID is used as a CAN node for the CAN bus.
If the device is connected to a SICK network via CAN, device IDs 1 to 63 can be assi-
gned. If the device is connected to a CANopen fieldbus, device IDs 1 to 127 can be assi-
gned. Duplicated IDs must not be assigned.
The device must be clearly identified on the network to enable communication via CAN bus
and to assign reading results to devices.
5.10.1.2
Device name
A name is assigned to the device via the
parameter. The device name appears
in SOPAS in the project tree.
It is not compulsory to assign a device name, although it can offer a better overview of all
devices in the system during the configuration process.
5.10.2
Master/Slave
In the
group, the device is configured as a SICK network participant in a ma-
ster/slave operating mode. A maximum of 10 slaves can be connected to a master. The ma-
ster sends the trigger signal to the slaves via CAN bus at the start of the reading process.
The slaves send the reading results to the master, which then sends the reading result in
the configured output format to the PLC at the end of the reading process. The PLC only re-
ceives a No Read for an unsuccessful reading result from the master if none of the slave
devices have sent a successful reading result (Good Read) to the master.
The SICK network in the master/slave operating mode is typically used to read objects that
can accommodate the code in various positions. Several reading devices can be used to
search for the existing code on all sides of the object. The master only transmits the reading
from the device with the successful reading result to the PLC. The unsuccessful readings
(No Reads) from the devices where no code was available are not sent to the PLC. This in-
creases the processing speed of the control system.
For additional information see the F1 help.
Wizard
Pressing the S
TART
WIZARD
button launches a dialog box via which the device can be confi-
gured in full as a SICK network participant in the master/slave operating mode. The wizard
provides the parameters required for configuring the CAN interface, device network func-
tions, output control, and object trigger control. The values entered into the wizard are ac-
cepted into the relevant parameter groups and tabs once the configuration is complete.
