WL Circuit Breaker

Data Availability on the CubicleBUS

All modules connected to the CubicleBUS can request data from other modules via the bus and generate data themselves that can be read by other modules.

Each data point in the comprehensive WL Circuit Breaker data dictionary can only be generated by a single module—the data source. If this data source (module) exists, the data points assigned to it also exist.

This information is described and communicated in the property bytes.

If a data source (module) does not exist, the data point does not exist either.

Again, the relevant property byte contains this information.

The following table provides an overview of the internal CubicleBUS modules and the data point groups (collection of several data points) assigned to them.

See Chapter 3 Register List for a detailed description of the individual data points.
