Control system of industrial machine

A control system of an industrial machine for matching data in a present device with data in one or more other devices, wherein the control system comprises:

• a changed data identification list including:
• regions of a type data storage unit serving as a superordinate class of type data;
• regions of a subdivision data type storage unit serving as a subordinate class of the regions of the type data storage unit;
• a first identifier storage unit indicating a first identifier that corresponds to each of the regions of the type data storage unit and identifies whether or not data in the respective region of the type data storage unit has changed;
• and a second identifier storage unit indicating a second identifier that corresponds to each of the regions of the subdivision data type storage unit and identifies whether or not data in the respective region of the subdivision data type storage unit has changed,
• the present device comprises:
• a changed data identification list storage unit storing the changed data identification list;
• a present-device-side data storage unit storing various data;
• and an updated data processing unit, and
• an other device comprises:
• an other-device-side data storage unit storing various data;
• and an operation execution unit using the various data to perform a desired operation,
• the control system configured such that the updated data processing unit uses the first and the second identifiers in the changed data identification list to check whether or not the data in the respective region of the subdivision data type storage unit has changed, transfers only the changed data in the respective region of the subdivision data type storage unit to the other devices, and matches the data in the present device with the data in the other devices.
