F&eIT™ Remote I/O Systems Migration Guide

CONPROSYS™ nano Series

As an advanced remote I/O system with reduced wiring, the F&eIT™ Series I/O Controller Units have been long supported and appreciated. However, we will be discontinuing sales and support for this series as of December 2025.
Going forward, we encourage you to transition to the CONPROSYS™ nano Series, which offers superior cost performance and enhanced functionality.

To assist with the migration from the F&eIT™ Series I/O Controller Units to the CONPROSYS™ nano Series, we will provide guidance on selecting communication couplers and I/O modules.

Coupler Units

Select a communication coupler according to the number of I/O modules required.

CPU-CA20(FIT)GY >> CPSN-MCB271-S1-041
>> CPSN-MCB271-1-041
>> CPSN-MCB271-1-081

I/O Module > Analog I/O

Select an I/O module according to the required precision (resolution) and number of channels. For details about the sampling rate, refer to the data sheet or manual.

Driver and Software

F&eIT CONPROSYS nano
Windows Linux

Dedicated driver for the F&eIT I/O controller unit. Contains APIs for digital I/O, analog I/O, counter, and other functions.

 >> Windows Linux

In CONPROSYS nano, drivers are provided for digital I/O, analog I/O, counter, and other functions. Install the driver for the required function.
Many API functions such as basic instructions are shared with API-CAP (W32).

example: Analog Input
API-CAP AIO >> API-AIO
example: Digital I/O
API-CAP DIO >> API-DIO
