•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.

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.
ARCHITECTURE
The 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.

• MIB for standard applications: available
• MIB for custom applications custom: “easy” to do
• MIB validator available on the internet
http://www.simpleweb.org/ietf/mibs/validate/
Technology & Evolution
MIB
The SNMP MIB is arranged in a tree-structured fashion, similar in many ways to a disk directory
structure of files.
The top level SNMP branch begins with the ISO “internet” directory, which contains four main
branches:….
Technology & Evolution
TRAP
SNMP traps are an important part of the SNMP standard, and
allow devices to self-report problems.
These traps are typically logged by the network manager, and
drive event notifications.
Traps are asynchronous and outside of the control of the
network manager

PcoWeb BacNet Database
•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.

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 04194303.
•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.
