Simulation control panel of virtual PLC

The utility model provides a simulation control panel of a virtual PLC for controlling the PLC, comprising a connection unit (2) and a hardware simulation circuit board (3). The simulation control panel is used for achieving the programmable logic control of a substance control object (18) composed by LED lights by a host computer (1). The simulation control panel is designed based on the development situation of the current virtual PLC. Compared with the prior art, the simulation control panel eliminates the step that a PLC program should be downloaded to a hardware PLC, and instead conducts the programmable logic control on the substance control object (18) directly. In terms of cost, a single-chip microcomputer has an obvious price advantage over the hardware PLC. The utility model is advantageous in that being a general module, the simulation control panel can control a plurality of substance control objects (18) and have good popularization value; the simulation control panel of virtual PLC is ingenious
