The present invention relates to a method of displaying information obtained through a programmable logic controller (PLC), and more particularly, to a method of displaying information obtained through a programmable logic controller

The present invention relates to a monitoring apparatus and method for monitoring an information of an external system.

Programmable Logic Controller (PLC: abbreviated as PIEC)

It is a key device of factory automation which is widely used, and handy loader is a device that sets up the operation program of the PI, operation condition and so on.

Various information of the external system operated by the PI, that is, the amount of production or the information of various types of ERP itself is very important in the operation of the system.

By displaying this information on the handy loader, the user can easily maintain system-wide maintenance.

Conventionally, the monitoring apparatus configuration of PIEC has a PEEL seed unit 10 for performing a programmable logic controller (PLC) program as shown in FIG. 1, A handy loader 20 that is connected to the online state and creates a PIEL seed program and sets operating conditions and the like; an external system 30 that performs a result of the PIEL seeding unit 10; And a monitoring unit 40 for monitoring various kinds of information such as a production amount, an error, and a warning.

The PIELL seed unit 10 includes a CPU 10a for controlling all functions, an input / output unit 10c for outputting a result of the PIELL program, receiving input data, and data of another PIELL or other type The handy loader 20 includes a CPU 20a, a display unit 20b for displaying various data, a keyboard 20c ).

The monitoring unit 40 includes a display unit 40a for displaying information and a keyboard 40b for generating information.

Hereinafter, a conventional technique configured as described above will be described.

The user creates a Piel seed program through the keyboard 20c of the handy loader 20 and sets the operation conditions and the like to transmit the peeling oil 20a to the input / output section 10c of the Piel seed section 10.

The PI system program is executed on the basis of the Piel seed program transmitted through the input / output unit 10c, the operation condition, and the like, and the external system 30 operates according to the result.

At this time, the handy loader 20 can monitor the data of the cube 10a itself or the input / output unit 10c through the cube 10a of the Piel seed 10.

The monitoring unit 40 likewise receives data from the input / output unit 10c of the PEEL seed unit 10 or the output of the external system 30 via the link unit 10b.

Information can be generated through the keyboard 40b of the monitoring unit 40 or the like.

However, in the related art as described above, the state or data of PIEL can be monitored using a handy loader, but it is only required to use a separate monitoring device to collect and monitor information about the external system.

There is a problem that additional cost is incurred for the user to provide a separate device to follow.

SUMMARY OF THE INVENTION Accordingly, the present invention has been made to solve the above-mentioned problems occurring in the prior art, and it is an object of the present invention to provide a handy- Of the cost incurred by the PI handy loader.

In order to achieve the above object, the monitoring method of the present invention includes a first step of checking whether a current mode is a monitoring mode, as shown in FIG. 3, A second step of performing a function of the loader itself and performing a function switching function so as to perform a monitoring function of the handy loader side in a monitoring mode and a second step of performing data switching, A third step of storing information in a data memory and obtaining information of an external system through the data or link part of PIEL in the monitoring execution mode, and a step of displaying information of the PI system or external system obtained in the third step It consists of four steps.

As shown in FIG. 2, the monitoring apparatus configuration of the present invention for performing the method comprising the steps described above includes a CPU 10a for executing a PIECE program, And a link unit 10b for exchanging data with the external system 30. The display unit 10 includes a CPU 20a and a display unit 20b for displaying various information, A key board 20c for setting up a PIea program and operating conditions if it is not a monitoring mode, a key board 20c for setting data and messages for monitoring in a monitoring mode, and a mode switching key And a data memory 20e for storing data and messages set in the monitoring mode. The monitoring unit 20 includes a handy unit 20 for monitoring the PI system 10 and the external system 30, Constitute a further 20.

The operation and effect of the present invention will be described in detail with reference to FIGS. 2 and 3.

If the mode selected through the mode changeover key 20d of the handy loader 20 is not the monitoring mode, the CPU 20a recognizes the mode and transmits it to the CPU 10 via the CPU 10a. Monitors the status of the Piel seed 10a itself, monitors the data of the input / output unit 10c, and displays the value through the display unit 20b of the handy loader 20.

If the mode selected through the mode switching key 20d of the handy loader 20 is the monitoring mode, the CPU 20a switches the function to the monitoring device.

In the case where this function is not executed in the state that the monitoring device is switched to the function of the monitoring device, the data to be set while performing the monitoring function, the message to be displayed, etc. are created using the keyboard 20c. Message and the like to the data memory 20e for storage.

Now, when the monitoring function is executed, the CPU 20a of the handy loader 20 obtains data from the CPU 10a of the PEEL module 10 connected to the handy loader,

The data may be data of the input / output unit 10c of the PEEL seed unit 10 according to the type of data requested by the CPU 20a of the handy loader 20 and may be data of the external system 30) (production volume, error occurrence, warning, .....).

The CPU 20a of the handy loader 20 displays the contents of the already prepared data memory 20e according to the kind of the information obtained above.

In this way, the handy loader 20 has a function of monitoring the PI system 10 and the external system 30, in addition to setting a conventional PI-ECU program and operating conditions.

As a result, in addition to the keyboard 20c of the handy loader 2, a mode switching key 20d for performing a function inherent to the handy loader and a monitoring function is provided. If the mode switching key 20d is not in the monitoring mode, And stores the data in the data memory 20e. When monitoring is performed in the data memory 20e, the CPU 10a of the PI cell 10 performs the setting of data, Output unit 10c via the link unit 10b and data in the data memory 20e on the display unit 20e in accordance with the type of the received information. So that it can perform a function as a monitoring device.

As described above in detail, according to the present invention, the handy loader further includes a mode switching key and a data memory to perform additional monitoring functions in addition to the original handy loader function, thereby solving the additional cost problem .
