Interoperation system, interoperation method, interoperation program, and interoperation auxiliary program

An interoperation method executed by an interoperation system including

• a controlled device included in a manufacturing apparatus,
• a PLC configured to control a first operation of the controlled device, and
• an information processing apparatus that is connected to the PLC via a communication network line and is configured to operate in conjunction with the PLC, wherein
• the PLC includes
• a PLC control unit configured to control the first operation, and
• a PLC storage configured to store a plurality of first device values to be used for controlling the first operation, and a plurality of second device values to be used for controlling a second operation of the information processing apparatus, wherein
• the plurality of first device values includes one or more first instruction values for causing the first operation to be executed, and
• the plurality of second device values includes one or more second instruction values for causing the second operation to be executed,
• the interoperation method comprising:
• a device value acquisition step of acquiring one or more of the second device values stored in the PLC storage at a predetermined time interval;
• an instruction value determination step of determining, after the acquisition of the one or more second device values, whether any of the second instruction values included in the acquired second device values have been changed;
• and
• an operation control step of controlling, when any of the second instruction values have been changed, the second operation corresponding to the changed second instruction value among the second operations.

A non-transitory storage medium storing an interoperation program executable by an information processing apparatus that is connected to, via a communication network line, a PLC configured to control a first operation of a controlled device included in a manufacturing apparatus and is configured to operate in conjunction with the PLC, wherein

• the PLC includes a PLC storage configured to store a plurality of first device values to be used for controlling the first operation, and a plurality of second device values to be used for controlling a second operation of the information processing apparatus, wherein the plurality of second device values includes one or more second instruction values for causing the second operation to be executed, and
• the information processing apparatus includes a processor,
• the interoperation program causing the processor to execute:
• device value acquisition processing of acquiring one or more of the second device values stored in the PLC storage at a predetermined time interval;
• instruction value determination processing of determining, after the acquisition of the one or more second device values, whether any of the second instruction values included in the acquired second device values have been changed;
• and
• operation control processing of controlling, when any of the second instruction values have been changed, the second operation corresponding to the changed second instruction value among the second operations.

A non-transitory storage medium storing an interoperation auxiliary program executable by a PLC that is configured to control a first operation of a controlled device included in a manufacturing apparatus, is connected to an information processing apparatus via a communication network line, and is configured to operate in conjunction with the information processing apparatus, wherein the PLC includes

• a PLC control unit configured to control the first operation, and
• a PLC storage configured to store a plurality of first device values to be used for controlling the first operation, and a plurality of second device values to be used for controlling a second operation of the information processing apparatus, wherein
• the plurality of first device values includes one or more first instruction values for causing the first operation to be executed, and
• the plurality of second device values includes one or more second instruction values for causing the second operation to be executed,
• the interoperation auxiliary program causing the PLC control unit to execute:
• second instruction value change processing of changing the second instruction value corresponding to the second operation in order to cause the information processing apparatus to execute the second operation;
• and
• first instruction value change processing of changing, based on an instruction from the information processing apparatus that has executed the second operation, the first instruction value corresponding to the instruction.
