Abstract

A recorder includes a wireless gateway unit built in the recorder, the wireless gateway unit being configured to wirelessly communicate with a field device, the wireless gateway unit converting between an internal communication protocol used for the internal communication of the recorder and a protocol used for the wireless communication. The recorder may further include a control unit that processes data from the field device. The wireless gateway unit is configured to internally communicate with the control unit. The wireless gateway unit collects the data from the field device to transmit to the control unit.

Claims

1. A recorder, comprising:

a controller configured to collect data from a field device configured to make a wireless communication via a repeater designed to satisfy an explosion-proof standard, the controller further configured to display on a display a waveform generated based on the collected data;

a wireless gateway wirelessly connected with the field device and configured to convert a wireless protocol used for the wireless communication of the field device into an internal communication protocol used for an internal communication of the recorder;

an ethernet connector coupled by wire to an external terminal device for use for parameter setting of the recorder so as to communicate with the external device; and

an ethernet switch built in the recorder and configured to relay communication data received from the wireless gateway to the controller,

wherein, the ethernet switch is also configured to relay communication data between the controller and the external terminal device for the parameter setting, and

the wireless protocol is either ISA100.11a or wirelessHART.

2. The recorder according to claim 1,

wherein a device identifier of the wireless gateway is already set in an initial state.

3. The recorder according to claim 1,

wherein the controller is further configured to process measurement data that is measured by the field device,

wherein the wireless gateway is further configured to internally communicate with the controller,

wherein the wireless gateway is further configured to collect the measurement data from the field device to transmit to the controller, and

wherein the wireless gateway has a device identifier for identifying the wireless gateway by the controller.
