Abstract
A control system includes a computer and at least one programmable logic controller connected to the computer. When the number of programmable logic controllers connected to the computer is one, the computer communicates with the connected programmable logic controller.
Claims15
A control system, comprising:
- an operation terminal;
- and
- controllers configured to be connected to the operation terminal, wherein the operation terminal comprises:
- a processor;
- and
- a memory including instructions that, when executed by the processor, cause the processor to perform operations including:
- broadcasting, using link local addresses of the controllers, a request for identification information to the controllers;
- receiving the identification information from the controllers and generating network configuration information on the basis of the identification information;
- determining a number of controllers connected to the operation terminal based on the network configuration information;
- and
- when the number of controllers connected to the operation terminal is one, establishing communication with the one controller connected to the operation terminal using a corresponding one of the link local addresses.

A non-transitory computer readable storage medium that stores a set of executable instructions, the executable instructions, when executed by a processor, cause the processor to perform operations comprising:
- broadcasting, using link local addresses of controllers, a request for identification information to the controllers, the controllers configured to be connected to an operation terminal;
- receiving the identification information from the controllers and generating network configuration information on the basis of the identification information;
- determining a number of controllers connected to the operation terminal based on the network configuration information;
- and
- when the number of controllers connected to the operation terminal is one, establishing communication with the one controller connected to the operation controller using a corresponding one of the link local addresses.
