When the user of the user terminal 8A instructs the execution of the parameter image generation processing application software, a program operation based on the parameter image generation processing application software starts.

(Step S1 in FIG. 3)
The information acquisition unit 21 shown in FIG. 2 has a definition file 35 (FIG. 4, FIG. 4) for displaying the parameters 37 of the process equipment 3 and the parameters 37 of the process equipment 3 shown in FIG. (See FIG. 6 or FIG. 8).

  As shown in FIG. 4, for example, the expert definition file 35 includes a “parameter name” indicating a parameter name, a “display name” indicating parameter notation, and a “value change” indicating whether or not the parameter value is changed. ”,“ Number of decimal places ”indicating the number of digits after the decimal point of the displayed value,“ Upper limit display ”indicating whether the upper limit value of the parameter is displayed,“ Indicating whether the lower limit value of the parameter is displayed ” It includes information such as “lower limit display” and “warning color” indicating a color used when a warning is issued when some abnormality occurs in the process control system.

  In “value change”, “True” indicates that the value can be changed, and “False” indicates that the value cannot be changed. In “Upper limit display”, “True” indicates that the upper limit value is displayed, and “False” indicates that the upper limit value is not displayed. In “Lower limit display”, “True” indicates that the lower limit value is displayed, and “False” indicates that the lower limit value is not displayed.

(Step S3 in FIG. 3)
The image generation unit 26 illustrated in FIG. 2 generates an image that displays the parameter 37 in a display mode that is predetermined for each user including a non-engineer, an expert, or an engineer based on the parameter 37 and the definition file 35. To do.

  FIG. 5 shows an example of an expert parameter table format image. Based on the parameters 1, 3, 4, and 6 of the thermometer 1, the thermometer 2, and the pressure gauge 1, and the definition file for the expert shown in FIG. As shown, an expert display image is generated.

  The parameter 1 column of the display image for experts includes the measurement information of two decimal places to each of the thermometer 1, the thermometer 2, and the pressure gauge 1, and the upper limit value and the lower limit value for the measurement information. . Here, permissible range information indicating the permissible range is defined based on the upper limit value and the lower limit value for the measurement information. For example, the allowable range information in the thermometer 1 is information indicating an allowable range (23.00 to 70.00) defined based on the upper limit value (70.00) and the lower limit value (23.00).

  Here, the parameter comparison unit 23 shown in FIG. 2 compares the measurement information with the permissible range for the measurement information, and the image generation unit 26 accepts the measurement information when the measurement information is outside the permissible range. An image indicating that the range is out of range is generated. Specifically, in parameter 1, the measurement information 43.21 of the thermometer 2 is outside the allowable range (lower limit value 22.5 to upper limit value 33.2), so the image generation unit 26 defines the definition shown in FIG. Based on the warning color “Red” of the file, the expert display image of FIG. 5 is generated so that the column in which the numbers of the measurement information 43.21 are arranged as the warning display is, for example, red.

  The parameter 3 column of the expert display image includes measurement information of one digit after the decimal point of each of the thermometer 1, the thermometer 2, and the pressure gauge 1, and an upper limit value associated with the measurement information. Permissible range information indicating a permissible range is defined based on the upper limit value. In parameter 3, the measurement information 63.2 of the thermometer 2 is out of the allowable range (upper limit value 34.7), so the image generation unit 26 is based on the warning color “Blue” in the definition file shown in FIG. Then, the expert display image of FIG. 5 is generated so that the column in which the numbers of the measurement information 63.2 are arranged as a warning display is, for example, blue.

  The column of parameter 6 of the expert display image includes measurement information of one decimal place of each of the thermometer 1, the thermometer 2, and the pressure gauge 1, and a lower limit value associated with the measurement information. Permissible range information indicating the permissible range is defined based on the lower limit value. In parameter 6, the measurement information 69.3 of the thermometer 1 is outside the allowable range (lower limit value 72.0), and the measurement information 23.2 of the thermometer 2 is the allowable range (lower limit value 34.7). 4), the image generation unit 26 displays the measurement information 69.3 of the thermometer 1 and the measurement information 23.2 of the thermometer 2 as warning displays based on the warning color “Red” in the definition file of FIG. The expert display image of FIG. 5 is generated so that the column in which the numbers are arranged is, for example, red.

  In the parameter 4 column of the display image for expert, each measurement information of the thermometer 1, the thermometer 2, and the pressure gauge 1 is included. Here, in the definition file shown in FIG. 4, “value change” of parameter 4 is set to “False”, so that the value cannot be changed. For example, in order to make it easy to grasp at a glance that the value cannot be changed, the parameter 5 column of the expert display image is grayed out.

  In the example of FIG. 5, the case where the measurement information of the process equipment 3 is adopted as the parameter of the process equipment 3 has been described as an example. However, the control information of the process equipment 3 is adopted as the parameter of the process equipment 3. You can also In this case, the parameter comparison unit 23 compares the control information with the allowable range for the control information, and the image generation unit 26 determines that the control information is out of the allowable range when the control information is out of the allowable range. It may be configured to generate an expert display image indicating the above.

  FIG. 7 shows an example of a non-expert parameter table format image. The image generation unit 26 is shown in FIG. 7 based on the parameters 1, 3, and 4 of the thermometer 1, the thermometer 2, and the pressure gauge 1, and the non-engineer definition file shown in FIG. Thus, a display image for non-engineer is generated.

  In the fields of the parameters 1, 3, and 4 of the non-engineer display image, each of the thermometer 1, the thermometer 2, and the pressure gauge 1 includes measurement information with one decimal place. Here, in the definition file shown in FIG. 6, since the “upper limit display” and “lower limit display” of each parameter 1, 3, and 4 are set to “False”, the upper limit for the measurement information in the non-engineer display image Values and lower limits are not included. In the definition file shown in FIG. 6, since “change value” of parameters 1 and 4 is set to “False”, the value cannot be changed. As in FIG. 5, the parameters 1 and 4 fields of the non-engineer display image in FIG. 7 are grayed out in order to make it easy to grasp that it is impossible to change the value.

  FIG. 9 shows an example of an engineer parameter table format image. As shown in FIG. 9, the image generating unit 26 is based on the parameters 1, 3, and 4 of the thermometer 1, the thermometer 2, and the pressure gauge 1, and the engineer definition file shown in FIG. Then, an engineer display image is generated.

  In the parameter 1 column of the engineer display image, the measurement information of two digits after the decimal point of each of the thermometer 1, the thermometer 2, and the pressure gauge 1, the upper limit value and the lower limit value associated with the measurement information, including. Here, permissible range information indicating the permissible range is defined based on the upper limit value and the lower limit value for the measurement information. For example, the allowable range information in the thermometer 2 is information indicating an allowable range (22.5 to 33.2) defined based on the upper limit value (33.2) and the lower limit value (22.5).

  Here, the measurement information is compared with an allowable range for the measurement information, and when the measurement information is out of the allowable range, the image generation unit 26 generates an image indicating that the measurement information is out of the allowable range. To do. Specifically, in parameter 1, the measurement information 43.21 of the thermometer 2 is outside the allowable range (lower limit value 22.5 to upper limit value 33.2), so the image generation unit 26 defines the definition shown in FIG. Based on the warning color “Red” of the file, the engineer display image of FIG. 9 is generated so that the column in which the numbers of the measurement information 43.21 are arranged as the warning display is, for example, red.

  The parameter 3 column of the engineer display image includes measurement information of one decimal place for each of the thermometer 1, the thermometer 2, and the pressure gauge 1, and an upper limit value associated with the measurement information. Permissible range information indicating a permissible range is defined based on the upper limit value. In parameter 3, since the measurement information 63.2 of the thermometer 2 is out of the allowable range (upper limit value 34.7), the image generation unit 26 is based on the warning color “Blue” in the definition file shown in FIG. Thus, the engineer display image of FIG. 9 is generated so that the column in which the numbers of the measurement information 63.2 are arranged as a warning display is, for example, blue.

  In the parameter 4 column of the engineer display image, the measurement information of the thermometer 1, the thermometer 2, and the pressure gauge 1 is included. Here, in the definition file shown in FIG. 8, “value change” of parameter 4 is set to “False”, so that the value cannot be changed. For example, in order to make it easy to grasp at a glance that the value cannot be changed, the parameter 4 column of the engineer display image in FIG. 9 is grayed out.

  As can be seen by comparing FIG. 5, FIG. 7, and FIG. 9, the expert display image shown in FIG. 5 has the largest number of display items and the widest possible operation range. It is. Then, in the order of the display image for engineers shown in FIG. 9 and the display image for non-engineers shown in FIG. In this way, a more advanced display is given to a user with a higher level of proficiency with respect to the process control system, and a simpler display is given to a user with a lower proficiency with respect to the process control system.

  In the example of FIGS. 5, 7, and 9, the image generation unit 26 generates a tabular image as each display image, but is not limited thereto.

  FIG. 10 is a diagram showing an example of a graph format image of parameters for engineers. As illustrated in FIG. 10, the image generation unit 26 may be configured to generate an image that displays the parameters 1, 3, and 4 of the thermometer 1 illustrated in FIG. 9 in a graph format. As shown in FIG. 10, the image displayed in the graph format is used as a warning display for a part out of the allowable range in the measurement information of parameter 1, that is, a part exceeding the upper limit 70.00 (dashed line part L1). The portion shown in red and out of the allowable range in the measurement information of parameter 3, that is, the portion exceeding the upper limit 72.0 (broken line portion L2) may be shown in blue.

  Here, when the user wishes to change the display item of the image after confirming the display image shown in FIG. 5, FIG. 7, or FIG. 9, the user changes the definition file 35 via the input unit 10. Enter instructions for. The definition file changing unit 25 changes the definition file 35 based on an instruction received from the user via the input unit 10 to change the definition file 35. The image generation unit 26 may be configured to generate an image for displaying the parameter 37 in a display mode predetermined for each user based on the parameter 37 and the definition file changed by the definition file changing unit 25. Good.

  For example, the definition file comparison unit 24 compares items of a common type between the non-engineer definition file and the expert definition file. Specifically, the definition file comparison unit 24 compares the “number of decimal places” (see FIG. 6) of the non-engineer definition file with the “number of decimal places” (see FIG. 4) of the expert definition file. If the definition file comparison unit 24 determines that the “number of decimal places” in the non-engineer definition file is larger than the “number of decimal places” in the expert definition file, the definition file for non-engineer has an error. Judge that there is.

(Step S15)
The image generation unit 26 illustrated in FIG. 2 generates an image including a warning display according to the comparison result of the definition file comparison unit 24.

  FIG. 12 is a diagram illustrating an example of a warning display image that notifies an abnormality of the definition file. As illustrated in FIG. 12, when the definition file comparison unit 24 determines that there is an abnormality in the non-engineer definition file, the image generation unit 26 warns, for example, the text “There is an abnormality in the definition file.” A warning display image including the display in the parameter table format image for non-engineer shown in FIG. 7 is generated. By generating such a warning display image, for example, when some abnormality occurs in the process control system and the altitudes of the non-engineer definition file and the expert definition file are reversed, the user Can be warned appropriately.
