ABSTRACT:
A data processing method which makes it unnecessary to run a user application program describing detailed conditions under which data on a device having a memory are acquired each time a system is started. A main controller forms a text format file as a data acquisition condition for a PLC from which data is to be acquired so that the data acquisition condition is associated with a label name, the data acquisition condition including a supervisory interval for supervising the status of the PLC and the operation status of the PLC for setting a trigger condition for starting data acquisition. When receiving the label name and the corresponding data acquisition condition from the main controller, a subcontroller develops and stores is the received data acquisition condition in a memory so that the data acquisition condition is associated with the label name. When receiving only the label name from the main controller, the subcontroller compares the data acquisition condition that is developed and stored in the memory with data of the PLC, acquires data from the PLC when the data acquisition condition is satisfied, and transfers the acquired data to the main controller.
