摘要：
The method of downloading application information from a host device to a field device over a network providing communication and power to the field device, the method including the steps of stopping the normal data processing of a connected control device, halting operation of device components not critical to the download operation, reducing the operating frequency of a microprocessor included in the field device and transmitting a new device application over the network.
