Parameterization of the diagnostics

In addition to the PROFIBUS standard diagnostics, the ASM 456 offers user-specific
diagnostics data structured in the form of device-related diagnostics.
Along with error messages that are also communicated with command processing,
diagnostics data contain cross-application information such as the start of a firmware update.
The diagnostics data can be read out as follows:
● As a plaintext display on S7 interfaces.
● Storage of the diagnostics data with the help of SFC 13 in the data area of an application.
● Evaluation with FB 125 or FC 125.
