The ASi-5 offers improved performance and usability over ASi-3, delivering 1.27 ms cycle time, 200-m cable length, and 96 slaves per segment. The application specified standard product (ASSP) is fully backward compatible with ASi-3 devices, while incorporating the shorter cycle times, higher bandwidth resulting from the use of Orthogonal Frequency Division Multiplexing (OFDM), enhanced diagnostics, and robustness associated with the ASi-5 standard.
The ASI4U-V5 ASSP features a fully verified and field-proven firmware that reduces the complexity associated with ASi-5 implementations, which minimizes design risks. It supports all bus topologies, including line, star, and tree. Users can also take advantage of integration with other industrial protocols such as IO-Link and HART.

Key features include:
- The integration of up to 96 devices, and operation down to 1.2 ms cycle time with less than 10 ns jitter compared with 5 ms cycle times for ASi-3 solutions
- Support for up to 200-m cable and 16 data bits per transport channel
- Diagnostics and event handling for Industry 4.0 applications
- Backward compatibility with ASi-3 devices
- Robustness against electromagnetic disturbers
- Fully verified and field-proven firmware
Reference samples of the ASi-5 ASSP are available now. Mass production is planned for March 2020.
