Fluid control device, fluid control system and fluid control method

A fluid control device comprising:

• a body inside which is formed a flow path;
• a fluid control valve that is mounted on the body and controls a fluid flowing through the flow path;
• and
• a casing that is mounted on the body in such a way as to house the fluid control valve, wherein
• a sloping surface that slopes towards the body is formed on a top surface of the casing, which is a surface facing towards an opposite side from the body,
• at least two Industrial Ethernet communication ports are provided on the top surface of the casing and are arranged in a line along a longitudinal direction of the top surface, the at least two Industrial Ethernet communication ports being disposed along a center of the top surface in a width direction, the width direction being orthogonal to the longitudinal direction,
• the at least two Industrial Ethernet communication ports are spaced apart from each other along the longitudinal direction by a distance corresponding to at least one port, and
• the sloping surface has a shape extending longer in the longitudinal direction than in the width direction, and a plurality of status lamps showing operational statuses of the fluid control device and/or a plurality of operating switches that are used to perform operations on the fluid control device are provided on the sloping surface and are arranged in a row along the longitudinal direction.
