1 PRESENTATION OF THE PRODUCT
pCOWeb
– order code PCO1***WDØ - is an accessory for the pCO * series products (excluding the pCOB* series) and more in general for CAREL products
fitted with a serial port and communication via the “CAREL supervisor” data protocol. pCOWeb acts a “gateway”, that is, a translator between the “CAREL
supervisor” data protocol and the Ethernet network protocols commonly used to connect the computers in a building. On the pCO * series products it is installed
on the “Serial board” port (also called “serial card” or “BMS"), from where it also receives the power required for operation. The cover supplied protects pCOWeb ,
especially when removing the network connector. The pCOWeb firmware can also be updated by the user.
Figure 1.a - pCOWeb: example of network connection
This manual refers to firmware version A2.0.4 – B2.0.4. To check the version loaded on the pCOWeb , see Section 9.2.2 on page 42. In the example shown in
Figure 1.a
sopra 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. This manual only covers the configurations of the
pCOWeb and the more simple
types of networks. For further information, see specific publications on the topic of “data networks”.
1.1 FUNCTIONS AVAILABLE
pCOWeb connected to an Ethernet network provides the following functions:
WEB server : used to check or change the operating status of the pCO controller using a remote computer running, for example, Mozilla Firefox, Google
Chrome or Microsoft Edge; dynamic web pages developed by the user can be added; supports CGI and Ajax technologies; supports protection for
accessing web pages;
• Logger : pCOWeb can record the values of some of the pCO controller variables in a file on its non-volatile memory; the file can then be downloaded to a
PC using your browser;
• Graphs : the trends over time of the data saved with the Logger function can be viewed on graphs;
• E-mail : pCOWeb can send e-mails when programmable events occur on the pCO controller (activation of alarms, exceeding of thresholds) or at set time
intervals; a file in XML format can be attached containing the values of the variables;
• FTP PUSH : pCOWeb can send a file in XML format containing values of the variables to a suitably configured computer; the send operations can be
programmed in the same way as for send the e-mail messages (upon event or at set times); the file is sent using the FTP protocol;
• SNMPv1 & v2 : to access pCOWeb from a computer using supervision software based on the SNMP protocol. pCOWeb can send programmable
enterprise TRAP or INFORM packets for alarm notifications;
• MODBus TCP/IP: pCOWeb supplies information to a MODBus master requesting it over TCP/IP;
• BACnet/IP (Addendum A/Annex J) : for access using supervision software based on the BACnet/IP protocol;
• BACnet Ethernet ISO8802-2 over 8802-3 : to access the pCO controller using supervision software based on the BACnet Ethernet protocol;
•
FTP and SCP servers : used to copy data files or web pages from/to pCOWeb in a simple manner, using programs based on dragging icons from one
window to another;
•
DHCP : used to connect pCOWeb to a local network using the method of automatic addresses assignment by a central server, rather than statically
setting the addresses on the individual devices; DHCP is active by default;
•
Plugins : used to add additional applications developed by CAREL or by the user in script or compiled format;
• Firmware update : the pCOWeb firmware can be updated from a computer;
•
pCO Application update : pCOWeb is able to update the pCO application (not the BIOS) of every type of pCO * controller (supernode included), except for pCO2* .
