ARM7 74MHZ
16MB RAM, 8MB flash
Linux
10Mbit
Protocols
HTTP (web pages 4MB)
SNMP (Simple Network Management Protocol)
BACnet (BACnet over IP and BACnet over Ethernet)
FTP server, FTP client (plug-in optional)

6. Introduction Serial Port n.1 BIOS: any version is good
pCO WEB act as a local supervisory sistem
SW application:
SERIAL1_PROTOCOL=1 (Carel Local (Slave))
19200 baud (default)
IDENT: not important (1-207, 0 not allow)

7. LEDs and Button
2 LEDs
Left LED : “Status” Communication with controller
Blinking Green = controller online
Green = inizializing
Blinking Red = installing default setting
Right LED : “Ethernet” Communication with LAN
Green = connect.
Red = LAN not connect
1 Button
During runtime : Reboot card. Press the button for 5 to 10 sec.
At start-up : copy the factory values from Flash to RAM Press the button. Power-on controller. As soon as the left LED starts blinking (red/off).The pCOWeb will make 3 fast blink = confirm.
IP address=
Subnet mask=
Username=httpadmin, password=fhttpadmin, etc…

8. Installing the board
Upload SW application into the board. Check protocol & baud rate (SERIAL1_PROTOCOL=1, INI_BAUD_SPV=4)
Plug the board into the serial port n.1 (BMS)
Connect pCOWEB to the PC
Test Plan : use cross cable
Switch On the control. Wait till the end of the boot (about 1min) Boot’s end when the left green LED blinks

9. Configuring the PC
Usually the TCP/IP configuration of the PC doesn’t match with the pCOWEB one(DHCP, subnet mask)
Change Network Properties/ Internet protocol (TCP/IP)

10. Configuring Browser (Explorer)
Disable the Proxy server
Run Explorer
Click tools/Internet options
Click Connection tab
Click LAN setting
Unselect Use proxy server…
Check Box

34. How to download/upload a page
An FTP client is required. (i.e. Explorer, TotalCommander, WS_FTP, SmartFTP, …)
Explorer: open Total Commander:
Login: Username: httpadmin, password: fhttpadmin
Root directory: ftp://
The new board have only 1 file: index.html Originale (R): /usr/local/root/defindex.html User (R/W): /usr/local/root/flash/http/index.html
Copy/Delete/Rename files is like your local disk (Drag&Drop)

35. How to download/upload a page

36. How to download/upload a page

37. How to create a WEB page You must know the HTML language
Pages must include the following lines(within the firsts 10 line) <!—tagparser=“/pcotagfilt”-->
Special tags (most common)
Read variable: <%VAR(0,t,i)%>
Write variable: GET method name=“script:var(0,t,i,min,max)” t=type. 1:digital, 2: analog, 3:integer. i=index 1…199 (Digital), 1…127 (Analogic, Integer). min, max=minimum/maximum value (i.e for analog)

38. Test page Test Page Show temperature, setpoint, cooling
Change Setpoint

39. Remarks
You can customize all pages (index, configuration ,etc) Use the system ones as template
Browser / View HTML command: You don’t see the real source HTML files. Carel tags are replaced with value.
Flash Memory
Reserved Area (about 4MB) Contains operating system and pages configuration. It isn’t possible to damage the content.
User Area (about 4MB) User pages are stored here.
When pCO WEB boots, firmware is copied into RAM, then continue to boot from RAM. System uses conf.params in RAM (important if you press the button)

40. Useful Address Index.html (user) Browser: 172.16.0.1
FTP:/usr/local/root/flash/http/index.html
Index.html (original)
Browser: not available
FTP:/usr/local/root/defadmin/index.html
Web administrator page (original)
Browser: /config/adminpage.html
FTP:/usr/local/root/flash/config/adminpage.html

41. FTP Client Plug In
The pCOWEB have the possible to send (time slot configurable) a .XML file (customize) to FTP server.
Connect to pCOWeb via FTP (user/password: root/froot)
Use an FTP Client: SmartFtp, LeechFtp (FREEWARE)
Advise: Your password can several of this: see USERS page
Download files configuration.
Configure FTP CLIENT & NTP CLIENT (address,pause,...)
Reboot pCOWEB

42. STEP A A-Copy these files: -ftp -ftp.sh -ntpdate -ntp.sh -xmlcreator
into:/usr/local/root/flash/bin_users
and give them the EXECUTE property

43. STEP B B-Copy these files: -ftp_script -ntp_script
into:/usr/local/root/flash/etc/rc_users
and give them the EXECUTE property

44. STEP C C-Copy these file: -template.xml
into: /usr/local/root/flash/etc/sysconfig/conf_users

45. STEP D D-copy these files: -ftp_client.html -ntp_client.html
into: /usr/local/root/flash/http/plugins
and give them the READ property

48. NTP
NTP
Network Time Protocol (NTP) is a system for the synchronization of computers clock time through the Internet; developed mainly near the Delaware university in the United States. They have been some defined 3 versions: the 1 in 1988, the 2 in 1989 and the 3 in The running version is 3, compatible with the previous ones. In order to facilitate the use of the NTP on notebook have defined the simplified version NTP (SNTP 1995).
The main characteristics of the NTP are following:
Is completely automatic and maintains the synchronization.
It’s possible to use with all types of computers.
Resistant to the breakdowns.
It diffuses UTC time, therefore is independent from time zone and the daylight time.
The synchronization precision is until 1 millisecond.
