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.
