One I/O module is used for each connected LOCC-Box-Net. There are two types:
- LOCC-Box-State with 1 byte input
- LOCC-Box-Mode with 1 byte output
Input byte
The module state of the connected LOCC-Box-Net is shown in the input byte (state). The module state
corresponds to the index 0x2010 (chapter 2.4.10.1) and is updated in cycles by the control system.
