Apparatus and method for field device management

Abstract

A correspondence storing section stores correspondence between a device type of a field device and an information processing algorithm conforming to the device type. A device type obtaining section obtains a device type of the field device from the field device. An algorithm selecting section specifies the algorithm corresponding to the device type obtained by the device type obtaining section based on the correspondence stored in the correspondence storing section, and selects the specified algorithm as an algorithm to be used for the field device.
