Abstract: A field device management system include a plurality of field devices equipped in a plant, one or more host devices equipped at a place distant from the plant and configured to connect to the field devices via a first network, and a terminal apparatus configured to connect to the field devices via a second network and to connect to the host devices via a third network. The terminal apparatus includes a first communication interface module configured to perform field communication with the field devices via the second network, a second communication interface module configured to perform near field communication with the host devices via the third network, and a controller that, when updating data of any one of the field devices, performs communication with the host devices through the second communication interface module, and receives update permission information from the host device through the second communication interface module.

Abstract: A battery diagnostic apparatus and a battery diagnostic method that are capable of accurately determining a deteriorated state of a battery and enabling use of the battery immediately before or near the end of the battery life are provided. The battery diagnostic apparatus includes a power supply monitoring unit 5 configured to detect that a power supply voltage has changed from less than a predetermined voltage to equal to or more than the predetermined voltage, and a controller 4 configured to measure a battery voltage in a predetermined period after the detection that the power supply voltage is equal to or more than the predetermined voltage, calculate electric power associated with a remaining capacity of the battery 1 based on the battery voltage, and perform deterioration determination of the battery 1 based on the electric power associated with the remaining capacity of the battery 1.
