Swap 16 (16-bit Data Swap) | This option swaps bytes for all word or double-word-sized datathe high byte and low byte in every word for all INT16, UINT16, INT16, UINT32, INT64, and UINT64 data types. The following diagram shows an example of byte-swapping:  Almost all data types will be influenced by this option except INT16 / UINT16 |
Swap 32 (32-bit Data Swap) | This option swaps words of all double-word-sized datathe high word with the low word in every double word of all INT32, UINT32, INT64, and UINT64 data types. The following diagram shows an example of word swapping:  Tag values with data types INT32 / UINT32 / BCD32 / UBDC32 / FLOAT32 will be influenced by this option. |
Swap 64 (64-bit Data Swap) | This option swaps words of all quadruple-word-sized data.Tag values with data types INT64 / UINT64 / BCD64 / UBDC64 / FLOAT64 will be influenced by this optionhigh double word with the low double word INT64 and UINT64 data types. |
Swap Float 16 | This option swaps the high byte and low byte in every word for the REAL (FLOAT32) data type. |
Swap Float 32 | This option swaps the high word and low word for the REAL (FLOAT32) data type. |
Swap Double 16 | This option swaps the high byte and low byte in every word for the LREAL (FLOAT64) data type. |
Swap Double 32 | This option swaps the high word and low word in every double word for the LREAL (FLOAT64) data type. |
Swap Double 64 | This option swaps the high double word and low double word for the LREAL (FLOAT64) data type. |
Swap String | Swaps the upper and lower bytes of string word data. |
String Encoding | Specifies the encoding method for reading and writing string values stored on the device. This option can be overridden for individual tags in the Edit Tag menu. |
