Information processing system, gateway, server, and information processing method

A gateway which is communicably connected to a controller included in each of one or more pieces of equipment in a production facility and is communicably connected, without being intermediated by the controller included in the each of the one or more pieces of equipment, to an externally attached sensor accompanying the each of the one or more pieces of equipment, the gateway being further communicably connected to a server,

• the gateway being configured to carry out processes of,
• receiving, from the server, collection setting data including information indicative of a kind of information to be collected and a time the information is to be collected,
• in accordance with the collection setting data, transmitting, at the time indicated by the collection setting data, to each of the controllers, information specifying a device in which information obtained by the controller and indicative of an internal state of a corresponding piece of equipment of the one or more pieces of equipment is stored,
• receiving, from each of the controllers, the information indicative of the internal state of the corresponding piece of equipment of the one or more pieces of equipment,
• in accordance with the collection setting data, requesting, at timing indicated by the collection setting data, from a sensor base unit, information indicative of an external state of the each of the one or more pieces of equipment,
• receiving, from the sensor base unit, the information indicative of the external state of the each of the one or more pieces of equipment, and
• transmitting, to the server, the information indicative of the internal state of each of the one or more pieces of equipment and the information indicative of the external state of each of the one or more pieces of equipment.

An information processing method for managing one or more pieces of equipment in at least one production facility,

• the information processing method comprising:
• receiving via a gateway communicably connected to a controller included in each of the one or more pieces of equipment and communicably connected to a sensor, from a server, collection setting data including information indicative of a kind of information to be collected and a time the information is to be collected;
• in accordance with the collection setting data, transmitting via the gateway, at the time indicated by the collection setting data, to each of the controllers, information specifying a device in which information obtained by the controller and indicative of an internal state of a corresponding piece of equipment of the one or more pieces of equipment is stored;
• receiving via the gateway, from each of the controllers, the information indicative of the internal state of the corresponding piece of equipment of the one or more pieces of equipment;
• in accordance with the collection setting data, requesting via the gateway, at the time indicated by the collection setting data, from a sensor base unit, information indicative of an external state of the each of the one or more pieces of equipment;
• receiving via the gateway, from the sensor base unit, the information indicative of the external state of the each of the one or more pieces of equipment;
• transmitting, to the server via the gateway, the information indicative of the internal state of each of the one or more pieces of equipment and the information indicative of the external state of each of the one or more pieces of equipment;
• and
• combining and outputting, via the server, the information indicative of the internal state of each of the one or more pieces of equipment and the information indicative of the external state of each of the one or more pieces of equipment received from the gateway.
