PROBLEM TO BE SOLVED: To provide field apparatuses capable of performing processing by mutually communicating information so as to reduce load on a control device and avoid a communication failure, and a communication system having the field apparatuses.SOLUTION: A communication system 1 comprises a plurality of field apparatuses 11 connected to a field network N1, and a controller 12 for controlling the field apparatuses 11 by performing communication with the field apparatuses 11 through the field network N1. Each of the field apparatuses 11 performs predetermined processing by using information obtained by performing communication with the controller 12 through the field network N1 and also performing communication with other field apparatuses 11 through a local network N3. |
