Multifunctional test system and method for IO-Link master station

The invention discloses a multifunctional test system and method for an IO-Link master station, belongs to the field of IO-Link master stations, and relates to a multifunctional test technology. Comprising a multifunctional testing device, an IO-Link master station and an upper computer configuration module, the multifunctional testing device is provided with one or more IO-Link interfaces, and the multifunctional testing device is connected with an IO-Link port of the IO-Link master station through the arranged IO-Link interfaces; a single IO-Link port of the IO-Link master station can be simulated to be connected with different types of IO-Link equipment for testing, and a plurality of ports can be tested concurrently, so that the capability of the IO-Link master station in coping with multi-port communication can be reflected more comprehensively and intuitively; the problem that a current IO-Link master station can only test a fixed type of equipment or can only test a single port during testing is solved
