Introduction


• 2 LEDs• Left LED : “Status” Communication with controller

• Right LED : “Ethernet” Communication with LAN

LEDs and Button

•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…


• 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)

pCOWeb SNMP

SNMP (Simple Network Management Protocol) is a communication protocol designed to manage TCP/IP networks and devices. Developed by the IETF (Internet Engineering Task Force) and adopted as a TCP/IP-based management standard in 1989.SNMP is a set of standards for network management including:

– a protocol, – a database structure specification, – and a set of data objects.

ARCHITECTUREThe SNMP architecture defines a Client/Server relationship.The Server (Network Management Station) executes management applications or directives which manage and control network elements. Clients (Network elements) are devices which have management agents responsible for performing the network management functions requested by the Server. The database, controlled by the SNMP agent, is referred to as the MIB (Management Information Base) and is a standard set of statistical and control values.

PcoWeb BacNet Database

Carel variables BACnet variables

Digital variable 1 Binary value instance 1

Digital variable 199 Binary value instance 199

Analog variable 1 Analog value instance 1

Analog variable 127 Analog value instance 127

Integer variable 1 Analog value instance 1001

Integer variable 127 Analog value instance 1127

•The pCO* communicated variables are mapped to analog_value and binary_value BACnet objects. •A table-based list of BACnet-visible values is maintained by the pCOWeb. •Each interface table value is accessible by BACnet clients as a Present_Value property of a standard object. •The Carel variable for each interface table slot defines the object type implicitly. •Analog variables are mapped to BACnet Analog Value object type with an instance number equal to their variable number, e.g. analog variable 17 would appear to be BACnet Analog Value 17. Because analog variables are implicitly scaled "times 10" their conversion to REAL in BACnet is scaled accordingly. So the value "123" which is taken to mean "12.3" is converted to a floating point "12.3" as the value for the AV object Present_Value property.•Integer variables are mapped to BACnet Analog Value object type with an instance number equal to their variable number plus 1000, e.g. integer variable 17 would appear to be BACnet Analog Value 1017. The integer value shall be converted to REAL in BACnet. So the value "123" should be converted to a floating point "123.0" as the value for the AV object Present_Value property.•Digital variables are mapped to BACnet Binary Value object type with an instance number equal to their variable number, e.g. digital variable 17 would appear to be BACnet Binary Value 17.

– DS-RP-B, DS-RPM-B, DS-WP-B, DS-WPM-Bi.e. act as a server that can execute Read/Write single or multiple properties

– DM-DDB-B, DM-DOB-Bi.e. dynamic device and object binding. Support initiating I-Am in response to Who-Is, and at configurable interval (Who-Is only, Who-Is plus startup, Who-Is plus every N minutes). This option is configurable through software.

– DM-DCC-B, DM-RD-Bi.e. DeviceCommunicationControl and ReinitializeDevice. These features shall support a Reinit Password configurable through software.

– AE-N-I-B, AE-ACK-B, AE-INFO-Bi.e. generate EventNotifications when programmed alarm conditions occur; accept acknowledgements for those notifications marked as requiring acknowledgement, and support GetEventInformation requests.

PcoWeb BacNet


PcoWeb BacNet•BACnet LAN Type: select the protocol to use BACnet/IP or BACnet Ethernet.•BACnetIP UDP: if BACnetIP is used then a UDP port must be assigned, the default port for BACnet is “BAC0” hexadecimal.•pCOWeb Device Instance: This is the device instance of the pCOWeb on the network. It defaults to 77000 but can be set from 0 to 4194303. Every device on the network must have a unique instance number.•Description: A 64 character field that can be used to describe the device. •Location: A 64 character field that can be used to describe the physical location.•APDU Timeout: Indicates the amount of time in milliseconds between retransmission of an APDU requiring acknowledgement for which no acknowledgement has been received. The default setting of this property is 5000milliseconds. This value must be non-zero if the APDU Retries is non-zero. In order to achieve reliable communication, it is recommended that the value of the APDU Timeout be the same in all intercommunicating devices.•APDU Retries: Indicates the maximum number of times that an APDU shall be retransmitted. The default value is 3. If the value of this property is non-zero, then the APDU Timeout field must be non-zero.•Password for Restart: This is the reinitialize password. The default is 1234. The value can up to 9 characters long. It is required from the responding BACnet-user prior to executing the ReinitializeDevice service.•Alarm Parameters:

•Alarming Enabled: Set to yes to enable the intrinsic alarming features of AV and BV objects.•Alarm Destination Device Inst: Insert the device instance of the destination for the alarms. Allowable range is 0-4194303.•Alarm Process Id: Insert the process Id or handle which is meaningfull to the alarm destination device. This handle will be used to identify the process within the destination device that should receive the alarm notification.

•Interval to send WhoIs: The pCOWeb will send a WhoIs command to the alarm destination device. WhoIs will continuely be sent at the interval provided until a valid response is received. Setting this value to 0 will disable this command.•Clock Parameters:

•Daylight Saving Time: Check yes if it is required to automatically track daylight savings time.•UTC offset: Universal Time Coordinated offset is used to enter an offset in minute resolution. The UTC time zone is GMT (or Zulu time in military terms). For example you would enter -300 to get Eastern Standard Time (EST).

Submit Button:Pressing the “submit” button will save your changes. Then you must reboot the pCOWeb by pressing the reset button on the card or by resetting power to the pCO* controller.

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.

• An FTP client is required. (i.e. Explorer, TotalCommander, WS_FTP, SmartFTP, …)

• Explorer: open ftp://[email protected] 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

How to download/upload a page


How to download/upload a 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)

How to create a WEB page


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

Test page


• 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)
