SYSTEM AND METHOD FOR LOADING SOFTWARE INTO A CONTROL PANEL FOR A CHILLER SYSTEM

摘要

A system and process for loading control software into the control panel 140 of a liquid chiller system 100 is provided. A PCMCIA card socket 218 is installed on a circuit board of a liquid chiller control system 140 and is i n direct connection with a data bus 210 and an address bus 208 for the microprocessor 202. A linear flash PCMCIA card having new control software f or the control panel 140 is inserted into the PCMCIA card socket 218 when the control panel 140 is de-energized. The control software from the PCMCIA card is loaded into a flash memory 204 of the control system 140 by software executed directly from the PCMCIA card. After the control software has been copied, control panel 140 is de-energized, the PCMCIA card is removed and th e chiller system 100 is restarted and executes the new control software stored in the flash memory 204.
