Claim 0:
1. 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:
