Abstract
A controller includes a receiver that receives specification of identification information representing a number that identifies a relay device that is connected to a plurality of instruments or a number that identifies a cable that connects the relay device and the controller; a search unit that searches an instrumentation database that records the identification information and input-output information on the instruments that are connected to the relay device in association with each other for input-output information corresponding to the specified identification information; and a setting unit that sets the searched input-output information in an input-output module of the controller.
Claims8
A controller comprising:
- function blocks that acquire information from one of a plurality of instruments that are set in a plant and control another of the plurality of instruments based on the acquired information, to form each control loop;
- a receiver that receives specification of identification information representing a number that identifies a relay device that is connected to the plurality of instruments or a number that identifies a cable that connects the relay device and the controller;
- a search unit that searches an instrumentation database that records the identification information and input-output information on the instruments that are connected to the relay device in association with each other for input-output information corresponding to the specified identification information;
- a setting unit that sets the searched input-output information in an input-output module of the controller;
- and
- a builder that specifies a function block among the function blocks that is connected to an instrument corresponding to the input-output information based on information that defines a connection relationship between the instruments and the function block and the input-output information that is searched for by the search unit, and builds the control loop that associates the instrument and the function block.
A setting method performed by a computer to execute a process comprising:
- building function blocks that acquire information from one of a plurality of instruments that are set in a plant and control another of the plurality of instruments based on the acquired information, to form each control loop;
- receiving specification of identification information representing a number that identifies a relay device that is connected to a plurality of instruments or a number that identifies a cable that connects the relay device and the computer;
- searching an instrumentation database that records the identification information and input-output information on the instruments that are connected to the relay device in association with each other for input-output information corresponding to the specified identification information;
- setting the searched input-output information in an input-output module of the computer;
- specifying a function block among the function blocks that is connected to an instrument corresponding to the input-output information based on information that defines a connection relationship between the instruments and the function block and the input-output information that is searched for by the searching;
- and
- building the control loop that associates the instrument and the function block.
A non-transitory computer-readable recording medium having stored therein a setting program that causes a computer to execute a process comprising:
- building function blocks that acquire information from one of a plurality of instruments that are set in a plant and control another of the plurality of instruments based on the acquired information, to form each control loop;
- receiving specification of identification information representing a number that identifies a relay device that is connected to a plurality of instruments or a number that identifies a cable that connects the relay device and the computer;
- searching an instrumentation database that records the identification information and input-output information on the instruments that are connected to the relay device in association with each other for input-output information corresponding to the specified identification information;
- and
- setting the searched input-output information in an input-output module of the computer;
- specifying a function block among the function blocks that is connected to an instrument corresponding to the input-output information based on information that defines a connection relationship between the instruments and the function block and the input-output information that is searched for by the searching;
- and
- building the control loop that associates the instrument and the function block.
