Abstract
A production system, comprising: a first industrial machine configured to control a second industrial machine based on each of a plurality of variables; and circuitry configured to input, to the first industrial machine, a control command relating to an operation of at least one of the first industrial machine or the second industrial machine, wherein the first industrial machine rewrites, based on the control command, at least one variable defined as a rewritable variable among the plurality of variables.

A production system, comprising:
- a first industrial machine configured to control a second industrial machine based on each of a plurality of variables;
- and
- circuitry configured to input, to the first industrial machine, a control command relating to an operation of at least one of the first industrial machine or the second industrial machine,
- wherein the first industrial machine rewrites, based on the control command, at least one variable defined as a rewritable variable among the plurality of variables,
- wherein the first industrial machine includes:
- a first control circuit configured to control the second industrial machine based on each of the plurality of variables;
- and
- a second control circuit configured to receive the control command, and
- wherein the second control circuit rewrites the at least one variable,
- wherein the first control circuit includes a first memory configured to store each of the plurality of variables,
- wherein the second control circuit includes:
- a second memory configured to store each of the plurality of variables to have each of the plurality of variables regularly subjected to matching with respect to the first memory;
- and
- a third memory configured to store the at least one variable corresponding to the control command,
- wherein the second control circuit is configured to:
- write the at least one variable stored in the third memory to the second memory;
- and
- write the at least one variable written in the second memory to the first memory.
