5.8.
ETHERNET LINK
5.8.1.
CONFIGURATION
The
CS8C
has
2
Ethernet ports,
J204
and
J205
. The
IP
address of each of these ports can be modified via the
control panel. The modification takes effect immediately. On delivery, the first port is configured with the address
192.168.0.254
(mask
255.255.255.0
) and the second one with the address
172.31.0.1
(mask
255.255.0.0
).
It is also possible to get automatically an
IP
address from the network (with
DHCP
protocol).
The
CS8C
controller can reach other Ethernet sub-networks, through gateways configurable from the Control
Panel.
Each gateway is defined with:
•
The
IP
address of the device used as gateway. The address must belong to the same sub-network as the
CS8C
controller.
•
The
IP
address of the sub-network to reach. A null address "
0.0.0.0
" can be used to define a default gateway,
to reach all sub-networks that are not handled by a specific gateway.
5.8.2. FTP
PROTOCOL
The
CS8C
controller is an
Ftp
server that enables file exchanges over the Ethernet. All that is required is to define
the
IP
address of the
CS8C
controller to enable it to be accessed via
Ftp
, and use a network login and password
corresponding to a user profile as defined on the
CS8C
. The reading and writing access rights depend on the login
user profile selected (see paragraph
5.10.3
).
A free client
Ftp
is supplied on the
SRS
CD-ROM.
5.8.3. MODBUS TCP
PROTOCOL
The
CS8C
controller can be configured to exchange Inputs/Outputs via the Ethernet using the
Modbus Tcp
protocol. In this case, the
CS8C
controller is considered as a Modbus Server .
The
CS8C
controller is configured for
Modbus Tcp
using the
PC SRS
software supplied on the
CS8C
CD-ROM
(Tools > Modbus IO Config). This tool is used to generate a
modbus.xml
file that has to be saved in the
/usr/applicom/modbus
directory of the
CS8C
emulator. Then the file has to be transferred to the
CS8C
controller
using the
SRS
transfer tool (Emulator > I/O > Modbus). If this file is present on start-up, the corresponding
Modbus Tcp
Inputs/Outputs are displayed on the control panel and are directly accessible via a
VAL3
application.
The
" Modbus TCP/IP Client"
software option for your PC provides access to
Modbus
Inputs/Outputs declared
on
CS8C
from
PC
software using OPC Client, ActiveX, DLL interface (f.i Visual Basic, Delphi, Visual C++,
LabView, ...). The
SRS
CD-ROM provides a trial version of the software in the folder
"DirectLink 3.9"
.
CAUTION:
The
DHCP
protocol may not always assign the same
IP
address to the controller. The
DHCP
mechanism should therefore not be used when the
IP
address of the controller is used by
other peripheral equipment.
The two Ethernet ports must correspond to different sub-networks. Two
IP
addresses on the
same sub-network are not supported.
