The pCOWeb card is used to interface the pCO Sistema to networks that use the HVAC protocols based on the Ethernet physical standard, such as BACnet IP, Modbus TCP/IP and SNMP.
BACnet is a communication protocol for building automation, based on the standards defined by US association ASHRAE (American Society of Heating, Refrigerating and Air-Conditioning Engineers). These standards consequently allow manufacturers to develop BACnet devices and make these interoperable with one another in different systems. Implementation of the standards is verified at BTL laboratories (BACnet Testing Laboratories) operated by the BACnet association. The pCOWeb card has been successfully tested by BTL laboratories.

Modbus (modbus.org) is the most widely-used protocol in HVAC/R, being very simple to implement in all development packages and featuring limited use of the system's HW & SW resources. Reference website: Modbus.org.
SNMP (Simple Network Management Protocol) is a protocol for IP networks defined by the Internet Architecture Board (IAB), in order to define commands used to exchange information between different devices over the network. Reference website: snmplink.org.
The card also features an integrated Web-Server, which both contains the HTML pages relating to the specific application and allows a browser to be used for remote system management. An internal logger is also provided for creating logs (.CSV file) of 20 variables, and a graph of 5 variables (.SVG file). These files can be received every day via e-mail.
The application on the pCO can be updated over a remote connection across an Ethernet network.
The embedded LINUX operating system allows applications (plug-ins) to be added, developed directly by users to meet their own requirements.
The pCOWeb card is compatible with the entire range of pCOSistema controllers that feature a BMS card slot: Supernode, pCOXs, pCO1, pCO3, pCO5 Compact, pCO5, pCO5+.
