1. A field device comprising:
- a communicator configured to communicate with a control device via a first communication path;
a local communicator configured to communicate with another field device via a second communication path, which is different from the first communication path; and
a processor configuredto perform a predetermined information processing using at least one of first information related to the field device itself and second information obtained by communication between the local communicator and the another field device via the second communication path,to share the first information and the second information with the another field device via the second communication path, andto diagnose abnormal states of the field device and the another field device using the first information and the second information.

Abstract
A communication system includes a plurality of field devices connected to a field network, and a controller configured to communicate with the field devices via the field network to control the field devices. The field device is configured to communicate with the controller via the field network, and to perform a predetermined processing using information obtained by a communication between the field devices via a local network.

15. A method for controlling a field device, comprising:
-
transmitting and receiving, by a hardware processor, information among a plurality of field devices via a first network connecting the field devices; performing, by the hardware processor, a predetermined processing in each field device using at least one of first information related to the field device itself and second information from another field device obtained by the transmittance and receiving of the information among the field devices; and transmitting, by the hardware processor, processing results of the predetermined processing from each field device to a control device via a second network connecting each field device and the control device, wherein performing the predetermined processing comprises; sharing the first information and the second information between the field device and the another field device via the first network; and diagnosing abnormal states of the field device and the another field device using the first information and the second information. - View Dependent Claims (16, 17, 18, 19, 20)
