Device-defined data types (1756-IF16)
Logix Designer
and FactoryTalk Design Studio
programming software automatically creates device-defined data types and tags when a device is created. This table shows the device-defined data types that are created for the device depending upon the the selected communication format.Comm Format | Device-defined Data Type |

* Differential mode on a 16-channel device means that only 8 channels are used resulting in IF8 in the input and configuration device-defined data types. | |
** High speed mode on a 16-channel device means that only 4 channels are used resulting in IF4 in the input and configuration device-defined data types. | |
*** Single-ended mode maximizes the number of usable channels on the device
(16 channels for the 1756-IF16). | |
