Abstract
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.
Claims6
A method of inputting same data into a plurality of programmable control logic controllers (PLCs), comprising the steps of:
- (a) obtaining a plurality of addresses corresponding to a plurality of memory blocks of a memory in a first PLC among the plurality of PLCs;
- (b) inputting data into the memory in the first PLC at the plurality of memory blocks according to the plurality of addresses;
- (c) preparing a program packet comprising the plurality of addresses corresponding to the plurality of memory blocks and the data stored in the plurality of memory blocks;
- (d) transferring the program packet into a second PLC among the plurality of PLCs;
- (e) executing the program packet in the second PLC so that the data may be inputted into a plurality of memory blocks corresponding to the plurality of addresses in a memory in the second PLC;
- and
- (f) repeating the steps (d) and (e).
A method of inputting same data into a plurality of programmable logic controllers (PLCs), comprising the steps of:
- obtaining a plurality sets of a starting address and an ending address corresponding to a plurality of memory blocks in a memory in a first PLC among the plurality of PLCs;
- inputting the same data into the plurality of memory blocks in the first PLC according to the plurality of addresses;
- preparing a program packet comprising the plurality sets of the starting address and the ending address and the data;
- transferring the program packet into a second PLC among the plurality of PLCs;
- and
- executing the program packet so that the data may be inputted into the second PLC at a plurality of memory blocks corresponding to the plurality sets of the starting address and the ending addresses.
