Abstract
A field device provided with a first communication unit for communicating over a communication network, a second communication unit for communicating via infrared with an external device, a converter for converting a message transmitted by the external device and received by the second communication unit into data that can be transmitted over the communication network, and a first controller for controlling the first communication unit and transmitting the data converted by the converter to the communication network.
Claims15
A field device comprising:
- a first communication unit configured to perform communication via a communication network;
- a second communication unit configured to perform infrared communication with an external device;
- a converter configured to convert a message, which has been transmitted from the external device and has been received by the second communication unit, into data which is transmittable to the communication network;
- and
- a first controller configured to control the first communication unit to transmit the data, which has been converted by the converter, to the communication network.
A communication system comprising:
- a field device including:
- a first communication unit configured to perform communication via a communication network;
- a second communication unit configured to perform infrared communication with an external device;
- a converter configured to convert a message, which has been transmitted from the external device and has been received by the second communication unit, into data which is transmittable to the communication network;
- and
- a first controller configured to control the first communication unit to transmit the data, which has been converted by the converter, to the communication network;
- an external device configured to transmit the message by infrared communication to the field device;
- and
- a host apparatus configured to receive the data transmitted from the field device via the communication network.
A communication method in a field device comprising a first communication unit performing communication via a communication network;
- and a second communication unit performing infrared communication with an external device, the communication method including:
- converting a message, which has been transmitted from the external device and has been received by the second communication unit, into data which is transmittable to the communication network;
- and
- controlling the first communication unit to transmit the data, which has been converted by a converter, to the communication network.
