Abstract

A safety controller includes a function block and a mapping block. The function block executes a function inherent to the safety controller. The mapping block converts data used in a control system among data handled by the function block into a data format which can be directly handled by the control system and also assigns a common tag to these data. Also, the mapping block performs calculation based on data handled by the function block and outputs a signal instructing whether to transmit a process alarm according to the calculation result. Also, the mapping block assigns a common tag to this signal. As a result, in the control system, it is possible to recognize that these data groups are related to one another.

Claims

1. An integration system for integrating a first system and a second system, wherein the first system comprises:

a function block for executing a function of the first system; and

a mapping block for converting data to be used in the second system among data handled by the function block into a data format which can be directly handled by the second system, and outputting the data by making the data be related to one another, and

wherein a data format of the data handled by the function block of the first system and the data format of the data handled by the second system are different.

2. The integration system as claimed in claim 1, wherein the mapping block performs calculation using the data handled by the function block and outputs the calculation result in the data format which can be directly handled by the second system.

4. The integration system as claimed in claim 1, wherein the second system is a control system for controlling a plant.

6. The integration system as claimed in claim 4, wherein the first system is a system for ensuring safety of the plant.

3. An integration system for integrating a first system and a second system, wherein the first system comprises:

a function block for executing a function of the first system; and

a mapping block for performing calculation using data handled by the function block and outputting the calculation result in a data format which can be directly handled by the second system, and

wherein a data format of the data handled by the function block of the first system and the data format of the data handled by the second system are different.

5. The integration system as claimed in claim 3, wherein the second system is a control system for controlling a plant.

7. The integration system as claimed in claim 5, wherein the first system is a system for ensuring safety of the plant.

8. A system integration method for integrating a first system and a second system, the system integration method comprising the steps of:

executing a function of the first system by using a function block; and

converting data to be used in the second system among data handled by the function block into a data format which can be directly handled by the second system, and outputting the data by making the data be related to one another,

wherein a data format of the data handled by the function block that executes the function of the first system and the data format of the data handled by the second system are different.

9. The system integration method as claimed in claim 8, comprising the step of:

performing calculation using the data handled by the function block and outputting the calculation result in the data format which can be directly handled by the second system.

11. The system integration method as claimed in claim 8, wherein the second system is a control system for controlling a plant.

13. The system integration method as claimed in claim 11, wherein the first system is a system for ensuring safety of the plant.

10. A system integration method for integrating a first system and a second system, the system integration method comprising the steps of:

executing a function of the first system by using a function block; and

performing calculation using data handled by the function block and outputting the calculation result in a data format which can be directly handled by the second system,

wherein a data format of the data handled by the function block that executes the function of the first system and the data format of the data handled by the second system are different.

12. The system integration method as claimed in claim 10, wherein the second system is a control system for controlling a plant.

14. The system integration method as claimed in claim 12, wherein the first system is a system for ensuring safety of the plant.

15. A computer readable medium having a system integration program for executing a system integration method for integrating a first system and a second system, the system integration program allowing a computer to execute the steps of:

executing a function of the first system by using a function block; and

converting data to be used in the second system among data handled by the function block into a data format which can be directly handled by the second system, and outputting the data by making the data be related to one another,

wherein a data format of the data handled by the function block that executes the function of the first system and the data format of the data handled by the second system are different.

16. The computer readable medium as claimed in claim 15, wherein the system integration program allows a computer to execute the step of:

performing calculation using the data handled by the function block, and outputting the calculation result in the data format which can be directly handled by the second system.

17. A computer readable medium having a system integration program for executing a system integration method for integrating a first system and a second system, the system integration program allowing a computer to execute the steps of:

executing a function of the first system by using a function block; and

performing calculation using data handled by the function block, and outputting the calculation result in a data format which can be directly handled by the second system,

wherein a data format of the data handled by the function block that executes the function of the first system and the data format of the data handled by the second system are different.
