CONNECTION TO AN INTERNAL NETWORK
In the example shown in Figure 1.a above pCOWeb is connected to an internal network. If suitably configured,
the personal computers in the internal network can communicate with pCOWeb using one of the various
standard network languages included on pCOWeb.
The server connects the external network or “Internet” to the internal network or “Intranet”.
Usually in a network, the exchange of data between Internet-Intranet is only enabled for some devices and only
for some types of communication.These decisions are defined by the network administrator.
pCOWeb features (Figure 1.b) a button (PUSHBUTTON) and two indicator lights (STATUS LED and
ETHERNET LED)
Functions of the button
• When starting up the pCOWeb, this is used to select, for network communication, whether to use the
factory parameters or the user parameters;
• In normal operation, reboots pCOWeb without needing to disconnect the power supply
Meaning of the LEDs
• Status LED: displays information on the communication status between pCOWeb and Pco and must
normally be green and flash around 3 times a second; in special circumstances it displays the
operation of service activities, such as the restart of the internal program on the pCOWeb, the remote
updating of the program, or others. See the table on the next page.

TABLE 1.a – Status LED signals
LED Status Meaning Notes
Green flashing (3 times/sec) Regular Pco-pCOWeb communication When running demanding tasks
(sending a large number of
notifications), this may be green
steady for a few seconds
Red flashing slowly (once every 2
seconds) Pco-pCOWeb communication not established
Single red flash and then flashing
green Single Pco-pCOWeb communication error, one failed
response from the Pco or attempt to
write a variable with an index higher
than 207.
After 5 failed responses, the Status
LED start flashing red until
communication resumes
Red steady Rescue mode
[Off, then] green-red repeated in
rapid succession, then green
steady for 1-2 minutes
PCOWeb reboot phase
Green steady for 1-2 minutes PCOWeb reboot phase Wait for the conclusion of the reboot
Red – Off slow (1second – 1
second) repeated 3 times Recognition of button pressed durino the reboot for selecting the

Release the button to confirm.
Red – Off fast (3 times a second)
repeated 3 times During the reboot, confirms the selection of the factory parameters
by pressing the button
Green-red repeated alternating
(once a second) During the firmware update, writing block B to non-volatile memory Do not interrupt the power supply
Red steady followed by green-red a
number of times During the firmware update, writing block B to non-volatile memory Do not interrupt the power supply
• Ethernet LED: displays the status of the physical network connection (Ethernet connection signals),
regardless of whether the network parameters are correct; usually this must be green and flash when
the data transits.

Equipment required:
• a 3mm flat-head screwdriver
• a map of the installation (only when installing two or more pCOWeb devices);
• a pair of scissors
IMPORTANT: to avoid damage, bifore inserting pCOWeb disconnect power to the controller.
Each pCOWeb is uniquely distinguished by its own MAC address. The network administrator may at times
need to check the MAC address of each pCOWeb installed.
The MAC address is shown on the label applied to the connector, and on the two labels included in the
packaging. Once installed, pCOWeb may however no longer be accessible.
Therefore, during installation use the scissors to separate the two labels supplied and apply one in an easily
accessible position near the pCO controller on the electrical panel.
If more than one pCOWeb devices is installed, a map of the installation should be created, applying the second
label provided in the packaging onto the map for each pCOWeb, corresponding to its physical position; in this
way, the network administrator can be provided with precise documents on where the pCOWeb devices and
corresponding MAC addresses are located.
INSTALLATION pCOWeb ON THE pCO CONTROLLER

pCOWeb
Version 1.0 August 2007 7
This chapter guides the user, even a non-expert, in establishing a connection between the pCOWeb and a
personal computer.
The chapter describes the pCOWeb – cable – personal computer (PC) connection, without involving an
Ethernet network.
This connection is used to access pCOWeb from a computer connected by a network switch and LAN cable.
Equipment required:
• A computer running, for example, Internet Explorer
TM
and fitted with an Ethernet network interface; if
pCOWeb is already installed in the final destination and cannot be removed, a portable computer is more
handy.
• A network cable.
Starting situation:
• PCOWeb installed on the pCO controller
• pCO controller NOT powered.
The steps to be completed are as follows:
1. Configuration of the PC for direct connection to pCOWeb
2. Connection and start-up of pCOWeb to check correct installation.
3. Activation of the factory network setting (button)
4. Access to the pCOWeb from the PC.
INFORMATION
The PC can comunicate with pCOWeb if settings on both devices are correctly aligned.
As the pCOWeb default settings can only be changed once the connection has been estabilished with the PC,
when first accessing the device the personal computer will need to be configured to adapt it to the pCOWeb
default settings.
It is necessary to have administrator status of your own PC and deactivate the Windows Firewall (see the
following diagram).

IP ADDRESS AND SUBNET MASK
The personal computer must be set not to use the DHCP, but rather the following IP address:
172.16.0.100. The Subnet mask field also needs to be set; the Gateway is not required.

C – PROXY
The following procedure tells the personal computer to not use the network device called the “proxy” for
communication: in fact, the PC is not connected to the network and if the “proxy” is not disabled communication
would not be possible.

2. Double click “Internet options”; the windows shown in Figure 3.d above (left) will be displayed
3. Click “Connections”. Another window (Figure 3.d – right) will be displayed.
4. Click “LAN Settings…”
