5.1. Diagnostics data on I/O mapping
The SI unit can be allocated diagnostics data as digital input data on I/O mapping, if one of the module,
Diagnostics type 1 or Diagnostics type 2, is configured. Use PROFINET master’s software to select a
requested diagnostics type to allocate the diagnostics data on I/O mapping.

・
The diagnostics on I/O mapping "US3 Diagnostics" and "US4 Diagnostics" are options which
can be enabled to use a special module.
