1756-IF4FXOF2F High speed analog I/O module

The 1756-IF4FXOF2F ControlLogix high-speed analog I/O module is an interface module that can convert analog signals at the input end to digital values, and can also convert digital values at the output end to analog signals. The module adopts the producer/consumer network model, 1756-IF4FXOF2F, which provides additional system functions while also generating information as required.

Here are some of the available features of the module:

. Input synchronization – This feature synchronizes multiple fast analog modules in the same rack

Sample the inputs so that they sample each other at the same rate for a few milliseconds. For more information, see “Synchronizing Module Inputs” on page 45.

. The combined module provides 4 differential inputs and 2 outputs

. Submillisecond input sampling

.One millisecond output update. Onboard alarm and scaling. Live plug (RIUP). Producer/consumer communication

. Data scroll timestamp (in milliseconds)

. The Coordinated System Time (CST) timestamp of the data in milliseconds. Ieee32-bit floating point

. Category I/Zone 2, UL, CSA, CE, and C-Tick agent certification

The performance characteristics of the 1756-IF4FXOF2F ControlLogix High speed analog I/O module vary depending on whether the module is running in a local or remote rack. Module performance in the remote rack is limited. The network cannot efficiently adapt the fastest refresh rate of the module because the data broadcast volume needs to occupy most of the bandwidth of the network. For maximum module performance, it is recommended that you use modules in your local rack.
