at least one item of building equipment;
a non-PLC controller communicably connected to the at least one item of building equipment to receive data from the building equipment, the non-PLC controller having a web server, a microprocessor and a memory storing a computer program executable by the microprocessor, the computer program comprising computer instructions for gathering data from the connected building equipment, capturing the data in CGI scripts, and populating the data into tags provided in an HTML web page generated by the web server of the non-PLC controller; and at least one HMI in communicable connection with the HTML web page.
2. The system of claim 1, wherein the building equipment is selected from the group consisting of heating, ventilation, and air conditioning equipment.
3. The system of claim 2, wherein the data are selected from the group consisting of alarms and faults, operational status, mode, settings, operational parameters, historical parameters, and combinations thereof.
4. The system of claim 3, wherein the operational parameters are selected from the group consisting of: compressor speed, fan speed, thermostat setting, refrigerant level, temperature, pressure, and combinations thereof.
5. The system of claim 3, wherein the historical parameters are selected from the group consisting of: run time, downtime, and maintenance.
6. The system of claim 2, wherein the gathering of data from the connected building equipment is performed automatically at predetermined intervals selected by a user.
7. The system of claim 2, wherein the gathered data is automatically retained for a preselected period of time or up to a preselected number files by a system component having data storage capacity.
8. The system of claim 7, wherein the preselected period of time can be adjusted by a user.
9. The system of claim 2, wherein the gathered data is automatically deleted from the system when the next CGI script is transmitted to populate the HTML web page.
