Next, the operation will be described. The central processing unit 2 executes the monitor display execution means 3a and the monitor condition registration means 3b. The monitor screen display means 3a is
As shown in the flowchart of FIG. 9, the monitor condition table 3d
The external device data is input through the interface device 6 based on the device ID / NO, and the monitor data is displayed at the designated position. Monitor condition registration means 3b
Is the external device name, as shown in the flowchart in FIG.
No, the monitor condition is input and the device name is converted into the device ID by referring to the standard device name table and stored in the monitor condition table.

[0006]

In the conventional monitor device, the designation of the monitor device is designated by the device name / NO, and the device name is designated by one or two letters of the alphabet such as "X", "Y", "W". Since only fixed names can be used, it is difficult to imagine the meaning of the device, and it was necessary to prepare a correspondence table of device names / NO and their meanings. There is also a monitor device that can be set with an arbitrary tag name instead of a fixed device name. However, in the device name fixing method, the device name and the actual device have a one-to-one correspondence, and thus the device name fixing method is better.

The present invention was made in order to solve the above problems, and an external device (monitor variable) is provided.
It is possible to specify both a device name (standard device name) fixed to the specification and a tag name, and to obtain a monitor device that simplifies monitor settings and makes it easy to understand the meaning of the device. .

[0008]

A monitor device according to the present invention has a tag name / standard device name judging means for judging whether a monitor variable is a tag name or a standard device name when registering monitor conditions, If the tag name is a standard device name corresponding to the tag name, monitor condition registration means is added to add a procedure for inputting NO, and if the monitor variable is the tag name when executing monitor display, the corresponding device name (ID) Monitor display execution means is provided for converting to NO, inputting external device data corresponding to the monitor variable, and displaying on the monitor.

[0009]

With the monitor condition registration means, the device name of the sequencer can be handled as both the actual device name at the time of programming and the tag name arbitrarily set by the user.

【Example】

Example 1. An embodiment of the present invention will be described below with reference to the drawings. In FIG. 1, 3c is a tag name / standard device name determination means, 3f is a tag name table, and others are the same as in FIG. 2 is a flow chart of the monitor condition registration means of the present invention, FIG. 3 is a flow chart of the tag name / standard device name determination means, FIG. 4 is a flow chart of the monitor display execution means, FIG. 5 is an example of a monitor display screen, and FIG. 6 is a monitor. It is an example of a condition table, a standard device name table, and a tag name table.

Next, the operation will be described. The central processing unit 2 executes the monitor display execution means 3a, the monitor condition registration means 3b, and the tag name / standard device name determination means 3c called by the monitor condition registration means 3b. The operation is executed as follows as shown in the flowcharts of FIGS. 2, 3, and 4. The monitor display execution means 3a, as shown in FIG. 4, is a monitor condition registration means 3b.
It is determined whether the monitor variable name of the monitor condition table 3d registered by is a standard device name or a tag name, and if it is a tag name, it is converted from the tag name table 3f to a device ID / NO corresponding to the tag name. If NO, external device data is input via the interface device and the monitor display is performed in the display type specified at the coordinate position registered in the monitor condition table 3d. The monitor condition registration means 3b executes the tag name / standard device name determination means 3c after inputting the monitor variable name and the monitor condition as shown in FIG. 2, and determines whether the input monitor variable name is the tag name or the standard device. If it is a standard device name, the device ID / NO returned from the tag name / standard device name determination means 3c and the monitor condition are registered in the monitor condition table 3d. If the monitor variable name is a tag name, enter the standard device name and device NO as the standard device name / NO corresponding to the tag, and register the monitor variable name (= tag name) and standard device ID / NO in the tag name table 3f. At the same time, the index and the monitor condition registered in the tag name table 3f are registered in the monitor condition table 3d. The above process is repeated until there is no monitor device input.

The tag name / standard device name determination means 3c is
The monitor variable name given by the monitor condition registration means 3b is input, and the monitor variable name is a combination of the device name and NO registered in the standard device name table 3e (for example,
If the device name is registered in the standard device name table 3e, the corresponding device ID is determined.
And decomposed into NO and registered in the return value. If the input monitor variable name is not registered in the standard device name table 3e, the monitor variable name is determined as a tag name and registered as a tag name in the return value.

[0013]

As described above, according to the present invention, a device to be monitored (monitor variable) is designated as a standard device name corresponding to a standard device or a tag name arbitrarily set by a user and the tag name. Since the standard device name and NO can be specified, the setting of monitor variables can be simplified, and it is easy to imagine the meaning of the device.
