| FB name | Function name | Description | Ver. |
|---|---|---|---|
| M+CPU-Data_CalculateCheckCode | Check code calculation | Calculates the horizontal parity value and addition value (sum), which are used to check for errors in communication. | 1.00A |
| M+CPU-Data_CalculateCRC16 | CRC-16 calculation | Calculates CRC-16 (Cyclic Redundancy Check) value, which is one of the error check methods used for communication. | 1.00A |
| M+CPU-Data_CopyDigit | Digit copy | Copies 16-bit data by digits (4 bits per digit). | 1.00A |
| M+CPU-Data_DSwap | 32-bit upper/lower byte exchange | Exchanges the upper/lower 8-bit of the input data (32-bit data) in word units. | 1.00A |
| M+CPU-Data_RShiftBit | Bit right shift | Shifts the word device data to the right by the specified number of bits. This FB transfers the data to be stored in the shift result from the most significant bit of the shifted data by the specified number of bits. | 1.00A |
| M+CPU-Data_LShiftBit | Bit left shift | Shifts the word device data to the left by the specified number of bits. This FB transfers the data to be stored in the shift result from the least significant bit of the shifted data by the specified number of bits. | 1.00A |
| M+CPU-Data_RShiftWord | Word right shift | Shifts the word device data to the right by the specified number of words. This FB transfers the data to be stored in the shift result from the most significant word of the shifted data by the specified number of words. | 1.00A |
| M+CPU-Data_LShiftWord | Word left shift | Shifts the word device data by the specified number of words to the left. This FB transfers the data to be stored in the shift result from the least significant word of the shifted data by the specified number of words. | 1.00A |
| M+CPU-Data_SortArrayData | Data sort | Sorts the data table, which consists of lines and columns, by lines in ascending or descending order based on a specified column. The data table stores consecutive values (16-bit data) in columns. | 1.00A |
| M+CPU-Data_DSortArrayData | 32-bit data sort | Sorts the data table, which consists of lines and columns, by lines in ascending or descending order based on a specified column. The data table stores consecutive values (32-bit data) in columns. | 1.00A |
| M+CPU-Data_SortArrayData2 | Data sort 2 | Sorts the data table, which consists of lines and columns, by lines in ascending or descending order based on a specified column. The data table stores consecutive values (16-bit data) in lines. | 1.00A |
| M+CPU-Data_DSortArrayData2 | 32-bit data sort 2 | Sorts the data table, which consists of lines and columns, by lines in ascending or descending order based on a specified column. The data table stores consecutive values (32-bit data) in lines. | 1.00A |
| M+CPU-Data_CheckBitStatus | 16-bit ON/OFF check | Checks the ON/OFF status of the specified bit position of 16-bit data. | 1.00A |
| M+CPU-Data_DCheckBitStatus | 32-bit ON/OFF check | Checks the ON/OFF status of the specified bit position of 32-bit data. | 1.00A |
| M+CPU-Data_SeachSameMaxMinData | Data search | Searches for the identical data and maximum and minimum values in consecutive data area (16-bit data). | 1.00A |
| M+CPU-Data_DSeachSameMaxMinData | 32-bit data search | Searches for the identical data and maximum and minimum values from the consecutive data area (32-bit data). | 1.00A |
| M+CPU-Data_CalculateSquareRoot | Binary data square root calculation | Calculates the square root of the input binary data (16-bit data). | 1.00A |
| M+CPU-Data_DCalculateSquareRoot | 32-bit binary data square root calculation | Calculates the square root of the input binary data (32-bit data). | 1.00A |
[Precautions for using the file]
- Install the FB library to the personal computer in which GX Works2 (English) of Version 1.31H or later has been installed.
[How to extract the compressed file]
Copy the file to a folder.
After the copied file is decompressed, the cpu-data_v100a_e folder is created.
Decompression method 1): For the OS with the ZIP-compatible decompression function
- Right-click the copied file.
- Select "Extract All...".
When "Extract All..." is not displayed, follow the decompression method 2). - Specify the location of the extracted file, and click the "Extract" button to start the decompression.
Decompression method 2): For the OS without the ZIP-compatible decompression function
- If not having the ZIP-compatible decompression tool, acquire the decompressing tool.
- Decompress the file using the decompression tool.
* Use the decompression tool at users' own risk.
[Installation method]
- Execute setup.exe in the cpu-data_v100a_e folder.
- Install the FB library following the messages of the installer.
[How to use MELSOFT Library]
- Select [Library] - [Install...] from the [Project] menu.
- In the [Import Library to Project] dialog box, select the installed library and necessary FBs, and click the [OK] button.
- Paste the FB from the [Element Selection] window to the program.
[Precautions for using MELSOFT Library]
- Before applying the FB library of MELSOFT Library to a system, check sufficiently if no problem occurs in the control of the system.
