Process data mode
Control bytes (for process data mode)
The control bytes are located in the output image and are transmitted from the controller to the terminal module.
CB1: Low byte

Name | RegAccess | - | Address | Scan | EnergyScan | Start | ||
CB2: High byte
Bit | CB2.7 | CB2.6 | CB2.5 | CB2.4 | CB2.3 | CB2.2 | CB2.1 | CB2.0 |

Key
Bit | Name | Description | |
|---|---|---|---|
CB2.0 to CB2.7 | reserve | 0bin | reserved |
CB1.7 | RegAccess | 0bin | Register communication off (process data mode) |
CB1.6 | reserve | 0bin | reserved |
CB1.3 to CB1.5 | Address | 0..7dec | In master mode, with whichever device the connection is running |
CB1.2 | Scan | 1bin | Activates scanning of the connected slaves (only possible in master mode). The scanned slaves can be found in register R38. |
CB1.1 | EnergyScan | 1bin | Activates the energy measurement for the 16 channels of the 2.4 GHz band. EnergyScan may not be activated in data exchange or scan mode. |
CB1.0 | Start | 1bin | Activates communication |
Status byte (for process data mode)
The status bytes are located in the input image and are transmitted from terminal module to the controller.
