Control system, setting device, and computer-readable storage medium

A setting device that performs setting on a control system including a control target and a plurality of devices, the control target and the plurality of devices being connected to a network, each device including:

• program storage configured to store a control program calculating control data using data exchanged with a control target;
• and
• execution module causing a processor to execute a plurality of programs including the control program,
• the setting device comprising a disposition module configured to cause a first processor to dispose a plurality of control programs in at least one of the plurality of devices,
• wherein the disposition module is configured to cause the first processor to determine the at least one of the plurality of devices in which the control program is disposed based on a communication delay time between the plurality of devices and information about a resource usable for execution of the control program of each of the plurality of devices for each control program,
• wherein the network implements a communication protocol with cyclic communication which guarantees an arrival time of data according to a time-sensitive networking (TSN) standard,
• wherein each device is time-synchronized with each other,
• wherein the information about the resource usable for the execution of the control program of each of the devices includes a time during which the processor is usable for the execution of the control program, and
• wherein the disposition module is configured to cause the first processor to compare, for each device, the usable time of the device with the time based on the time synchronization and shared among the plurality of devices, and determine the device where the control program is disposed based on the comparison.

A non-transitory computer-readable storage medium for storing a computer program that performs setting on a control system including a control target and a plurality of devices, the control target and the plurality of devices being connected to a network, each device including:

• program storage configured to store a control program calculating control data using data exchanged with a control target;
• and
• execution module causing a processor to execute a plurality of programs including a control program, the execution module being included in each of the plurality of devices,
• the computer program causes a computer to execute:
• acquiring a communication delay time between the plurality of devices and information about a resource usable for execution of the control program of each of the plurality of devices for each control program;
• and
• determining a device in which the control program is disposed from among the plurality of devices based on the communication delay time between the plurality of devices and the information about the resource usable for the execution of the control program of each of the plurality of devices for each control program,
• wherein the network implements a communication protocol with cyclic communication which guarantees an arrival time of data according to a time-sensitive networking (TSN) standard,
• wherein each device is time-synchronized with each other,
• wherein the information about the resource usable for the execution of the control program of each of the devices includes a time during which the processor is usable for the execution of the control program, and
• wherein the computer program causes a computer to execute:
• comparing, for each device, the usable time of the device with the time based on the time synchronization and shared among the plurality of devices, and determining the device where the control program is disposed based on the comparison.
