Identifier-Related Diagnostics:

For each identifier byte assigned during configuration (for example, 0 x 10 for 1 byte input), a bit is reserved.

In the case of a modular system with an identifier byte each per module, module-specific diagnostics can be indicated. One bit respectively will then indicate diagnostics per module.
