What is PLC file?

The PLC file has been categorized as Developer Files. The author of this format is Sunbelt. In addition to this file, the Developer Files category includes 1205 related files. PL/B Source Format is most often found on 2 operating systems. These systems consist of Linux, Windows, although it may occasionally be found on another system, it will be non-functional. Alternatively, you can use 1 other programs.

How to open PLC file?

The main problem with PL/B Source Format is that the PLC file is incorrectly associated with programs. Thus, when you open PLC, the program selection wizard or some other program starts. This problem can be easily remedied.

The first thing you should do is just "doubleclick" on the PLC file icon you want to open. If the operating system has an appropriate application to support it and there is also an association between the file and the program, the file should be opened.

Step 1. Install isual PL/B

In this case, you should first verify that the isual PL/B application is installed on the computer. To do this, enter the name isual PL/B into the system search engine. If we do not have this program, it is worth installing it, as it will help you automatically associate the file PLC with isual PL/B. Later in this article you will find a list of programs that can open PLC files.

Programs to open PLC file

Remember to download programs supporting PLC files only from verified and safe sources. We suggest using the websites of software developers.

Step 2. Create association of isual PL/B with PLC files

If, despite the installed application, the PLC file does not start in the isual PL/B application, you must create a file association. It is most convenient to call the context menu with the right mouse button and select Properties. The displayed window will contain information about the program that supports this type of file. Using the "Change" button we can set the program to handle this type. The program should be visible in the window, otherwise it should be selected manually using the "Browse" button and the program installation directory should be indicated. The "always use the selected program ..." field will set the isual PL/B application as the default for handling the PLC file.

Step 3. Update isual PL/B to the latest version

If, however, after binding isual PL/B with PL/B Source Format there were still problems, you should update the program to the latest version.

Step 4. Check for the following problems with the PLC file

If the above steps do not help, you can assume that the file itself is not correct. File problems can be divided into the following:

Very often, the file may be size 0 or incomplete. This is most often caused by a problem while downloading the PLC file. The only repair option is to download the file again.
The computer may have fallen victim to a computer virus or hacker. A virus scan using an up-to-date antivirus program should fix the problem. Some antivirus vendors also provide free online scanners. However, it is important to scan the entire system, not only the file PLC or the program directory. However, remember that not every infected PLC file can be recovered, so it is important to take care of regular backups.
Older version of PLC file may not always be supported by the latest software version. Help should be sought from the software developer, as they usually recommend using free file converters or installing an older version of the program.
The file may be corrupted in a number of ways. Depending on the type of file, it is necessary to repair it accordingly. Sometimes the program itself has options to repair the most popular PLC file corruption.
The program can also signal the fact of encryption. The encrypted PLC files can be used by the device on which they were encrypted, on any other device it is required to have the appropriate cryptographic key and decrypt the file before its recovery.
The operating system protects files in some locations (e.g. the root of the system partition) against unauthorized access. The problem is only writing to the file, not reading it. It is best to move PLC to a different directory.
This problem only occurs with more complex files. Some file types can only be opened in one program at a time. Closing other programs should help. Sometimes you have to wait for the session to the file PLC to close. However, some background programs may block the PLC file while scanning. If this does not work either, restart the device.
