Can we monitor precision air conditioner remotely ?

  • Yes, using an SNMP card, also known as a pCOWEB card, we can monitor the device remotely. Through the use of an SNMP card, we may connect the Close control unit to the LAN/WAN network and assign it an IP address. We can view real-time data from a nearby control unit with the usage of an IP address. Dry contact units, which come standard, can also be utilized to connect the unit to a building management system (BMS).
  • The pCOWeb card must be added in order to connect the pCO Sistema to networks that use HVAC protocols based on the Ethernet physical standard, such as BACnet IP, Modbus TCP/IP, or SNMP.
  • BACnet is a building automation communication protocol based on the American Society of Heating, Refrigerating, and Air Conditioning (ASHRAE) standards (American Society of Heating, Refrigerating, and Air-Conditioning Engineers). As a result of these standards, which are available to manufacturers, BACnet devices can be built and made interoperable with one another in a variety of systems. The BACnet organization maintains BTL laboratories (BACnet Testing Laboratories) to ensure that standards are being implemented correctly. The pCOWeb card has been evaluated successfully by BTL laboratories. Bacnet.org is a good starting point.
  • Modbus (modbus.org)is the most widely used HVAC/R protocol since it is reasonably easy to integrate into all development packages and consumes a small amount of the system’s HW and SW resources. Modbus.org is a valuable resource.
  • SNMP (Simple Network Management Protocol) was developed by the Internet Architecture Board (IAB) as a protocol for IP networks in order to enable commands for exchanging data between various devices connected to a network. As a resource, snmplink.org is available:
  • Additionally, the card includes an integrated Web-Server that keeps the HTML pages associated with the particular program and enables remote system control via a browser. Additionally, an internal logger is provided for the creation of logs (.CSV files) for twenty variables, as well as a graph for five variables based on the data from the logs (.SVG file). On a regular basis, these files will be sent via e-mail.
  • A remote connection over a network such as the Internet can be used to update the application running on the pCO.

It is possible to integrate software (plug-ins) written directly by users into the embedded LINUX operating system in order to meet their special requirements.
