    摘要: A method of inputting same data into a plurality of programmable logic controllers (PLCs) is disclosed, in which to-be-inputted data is first inputted to a first PLC among the plurality of PLCs and the inputted data in the first PLC are then written first into a second PLC among the plurality of PLCs by forming a program packet, transferring the data into the second PLC and automatically executing the program packet in the second PLC. In the same manner, other PLCs among the plurality of PLCs may be inputted with the same data. Therefore, the data inputting process into the plurality of PLCs may be much simplified and thus the process time may be considerably reduced.

    摘要: A method of partitioning a control program among many spatially separated computing devices places most of the program instructions in computing devices supporting outputs to the controlled processor equipment. Inputs then simply report their data to the output computing devices rather than having that data processed by a path of computing devices communicating with each other such as may cause the evaluation of the outputs to be delayed by multiple transmissions on the common link.
