9.2 Computer - c.pCO connection
There are two ways to connect the c.pCO controller to a computer via
Ethernet:
1.
computer-c.pCO direct connection;
2.
network LAN connection with DHCP server
C
omputer-c.p
CO
direct connection
Connect one end of the network cable to the Ethernet port on the
computer and the other end to a any of the Ethernet ports on the
c.pCO; LEDs blinking indicate correct connection. The Ethernet ports on
the c.pCO are auto-crossing (Auto MDI-X), therefore no crossover cable
is needed. After connection through Ethernet cable, computer and
controller IP addresses must be properly configure in order to belong to
the same IP subnetwork.
Configuration example:
Computer:
IP address: 192.168.0.2
Subnet mask: 255.255.255.0
c.pCO controller:
1.
press Alarm and Enter together for 3 seconds to access the system
menu;
2.
Select Settings -->TCP/IP settings: DHCP = OFF and enter an address
in the same subnet set on the PC, for example:
IP: 192.168.0.1
MASK: 255.255.255.0
3.
Select update configuration --> Yes

server
Before connecting the c.pCO controller to the LAN, access the system
menu and verify that DHCP: On (default setting).
Then connect the c.pCO to the LAN. The IP address is automatically
assigned to the c.pCO by the DHCP server, and it can be displayed in the
system screens (Settings -->TCP/IP settings).
9.3 FTP connection with authentication
Once having connected the computer to the c.pCO via Ethernet, FTP
protocol can be used to transfer files. The program used in this example is
“FileZilla”, downloadable for free from the Internet.
Proceed as follows:
1.
open FileZilla: the following screen will be shown;
2.
enter the IP address (or hostname) of the c.pCO controller, the user
name --> anonymous and password -->“empty” and select “Quick
Connect”;
3.
the user can access all the directories highlighted, as these do not
contain the “ftaccess” file: UPGRADE, HTTP. Access is also available to
the HTTP directory and its sub-directories.
Nota:
Please use following settings in Filezilla:
•
Edit->Settings->Connection-> set timeout in seconds = 0
•
Edit -> Settings -> Transfers -> set maximum simultaneous transfers to 1
