RELEASE 2026: Support of BOOL ProcessData cyclic exchange for B&R IO-Link Masters

Hello B&R Community,

We are pleased to announce the release of new hardware upgrades for B&R IO-Link Masters.

With these upgrades, the data type BOOL[8] is now also available for input and output process data. This means that the eight bits are stored as individual Boolean values directly in the I/O mapping.

This makes handling bit-based process data easier and more transparent, as each bit can now be accessed and used as a separate Boolean signal in the application.

The following hardware upgrades include this new functionality:

X20DS438A         2.5.0.0
X20cDS438A        2.5.0.0
X67DS438A         2.3.0.0
X20DS838A         1.1.0.0
X67DS838A.L12     1.2.0.0
X67DS838B.L12     1.2.0.0
X90DSI00.04-00    1.4.0.0

After installing the corresponding hardware upgrade, BOOL[8] can be selected for supported input and output process data and will be shown as eight individual Boolean values in the I/O mapping.

The configuration can be scaled up to 8 BOOL[8] values per direction, as with other supported data types.

This addresses some previous pain points, such as the one described here:

Enjoy the new feature!

Best regards,

Filipe Costa
