2. Description of the Related Art Conventionally, programmable logic controllers have been widely used for controlling equipment such as factory equipment, but this type of programmable logic controller is used for relatively large-scale and complicated control. To create a program, a separate program support device is required.

On the other hand, there has been proposed a memory relay having a function of creating a program and a function of controlling a device in a body for use in relatively small-scale and simple control. By the way, since this memory relay is usually manufactured in a language specification corresponding to the country of use, a memory relay is manufactured for each language. However, there are problems in terms of production efficiency, inventory management, and the like.

[0004] In order to solve this problem, a language for switching and selecting a language to be used by a language switch has been gradually provided.

[0005]

By the way, in the conventional example using the above-mentioned language changeover switch, a language changeover switch must be separately provided. There is a problem that the operating language is changed by operating the device.

In other words, the language used for the user is 1
Therefore, it can be said that the above-mentioned language switch is unnecessary in practical use. The present invention has been made in view of the above problems, and an object of the present invention is to provide a memory relay capable of switching languages without increasing the number of switches.

Another object of the present invention is to provide a memory relay in which, in addition to the object of the above-described claim 1, a user's erroneous operation is prevented and a used language is prevented from being inadvertently switched. Is to do. A third object of the present invention is to provide, in addition to the object of the second embodiment, a memory relay which can prevent a user from erroneous operation.
