Externally-connected shop floor control system

An externally-connected shop floor control system, being applied in a production line having M test machines and M information read-out devices, wherein each of the M information read-out devices is adopted for reading out an object information from a test object that is transferred into one of the M test machines, and the externally-connected shop floor control system comprising:

• M shop floor control (SFC) devices, wherein each of the M SFC devices is connected between one of the M information read-out devices and one of the M test machines, and comprising:
• a first communication interface for being coupled to the information read-out device;
• a second communication interface for being coupled to the test machine;
• a network communication interface;
• and
• a data processing module, being coupled between the first communication interface and the second communication interface, and being also coupled to the network communication interface;
• wherein there are a plurality of functional units provided in the data processing module, and the plurality of functional units comprising:
• a device setting unit, being used for completing a parameter setting of the SFC device according to at least one machine information of the test machine;
• a data acquiring unit, wherein before the test object is transferred into a N-th one of the M test machines for being executed an object testing, the data acquiring unit is, according to the object information transmitted from the information read-out device, configured for acquiring a plurality of test data of the test object from a (N−1)-th one of the M SFC devices that is connected to a (N−1)-th one of the M test machines through the network communication interface;
• wherein the plurality of test data comprising a data of test result of the test object;
• and
• a verification unit, wherein before the N-th one of the M test machines starts to execute the object testing for the test object, the verification unit applying a re-verification to a pass record from the data of test result, such that the N-th one of the M test machines is allowed to execute the object testing for the test object in case of the pass record having indicated that the object testing executed by the (N−1)-th one of the M test machines is passed;
• wherein both M and N are an integer, and M being greater than N.
