5. Diagnosis

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.
5.1.1. Diagnostics type 1
5.1.1.1. General diagnostics 1
Bit Description
0 System fault
1 Valve-coil(s) short circuit
2 Module error
3 Changed module layout
4 US1 Diagnostics
5 US2 Diagnostics
6 US3 Diagnostics
7 US4 Diagnostics
NOTE
・ The diagnostics on I/O mapping "US3 Diagnostics" and "US4 Diagnostics" are options which
can be enabled to use a special module.
