pCOWEB

pCOWeb 2 different add-on cards PCO1000WB0 - ETHERNET : BACnet Ethernet BACnet over IP SNMP v1, v2.c HTTP (web server) FTP, DHCP,... available PCO1000BB0 - EIA 485 : BACnet MS/TP prototype September 2005

pCO 2 pCO C pCO 1 pCO B pCO XS pCO 3 pCO available pCO 2 pCO C pCO 1 pCO B pCO XS pCO 3

pCOWeb It allows to access to the variables of the controller (pCOx) through a common Ethernet LAN. Board features Power by pCO ARM7 74MHZ 16MB RAM, 8MB flash Linux 2.4.21 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) NTP (Network Time Protocol) (plug-in optional)

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)

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=172.16.0.1 Subnet mask=255.255.0.0 Username=httpadmin, password=fhttpadmin, etc…

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

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)

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

Accessing to the main page Run Explorer (or other browser) 172.16.0.1 (default address for the new card)

How to download/upload a page An FTP client is required. (i.e. Explorer, TotalCommander, WS_FTP, SmartFTP, …) Explorer: open ftp://httpadmin@172.16.0.1 Total Commander: 172.16.0.1 Login: Username: httpadmin, password: fhttpadmin Root directory: ftp://172.16.0.1 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)

How to download/upload a page

How to download/upload a page

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. 20.0 for analog)

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

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)

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: 172.16.0.1/config/adminpage.html FTP:/usr/local/root/flash/config/adminpage.html

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

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

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

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 1992. 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.
