Item | Description |
|---|---|
Device Name | Allows the user to assign a name for the selected I/O device. |
Device Protocol | Allows the user to select a protocol for a device. |
Timeout (ms) | The maximum time to wait with no response before assuming a communication failure. |
Retry Count | Set the number of retries for sending a frame when communication fails. |
Swap 16 (16-bit Data Swap ) | This option swaps bytes for all word or double-word-sized data. 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 data. The following diagram shows an example of word swapping:  Tag values with data types INT32 / UINT32 / BCD32 / UBDC32 / FLOAT will be influenced by this option. |
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. |
String Encoding Method | When an invalid character is encountered, the gateway will do one of the following:
