Abstract

A human machine interface device and an interface integration method thereof are provided. The human machine interface device cooperates with a programmable logic controller. The programmable logic controller comprises a first program unit and a second program unit. The human machine interface device comprises a processor and a memory. The memory comprises a first address storing an operation variable and a second address storing a first common variable. The operation variable corresponds to the first logic operation via the first common variable. When the types and the amounts of the input/output parameters of the first program unit and the second program unit are the same, the processor causes the operation variable to correspond to the second program unit by updating the first common variable into a second common variable.
