In conformity with PROFIBUS
®
standard, the device makes the
[Get_Sl_Diag]
service available. The diagnostics data comprise
standard diagnostics information (6-Bytes according to PRO‐
FIBUS
®
standard) and any possible diagnostics data specific to the
device. A maximum of 63 bytes can be inserted for the device-spe‐
cific diagnostics data. The first 4 bytes in the PROFIBUS
®
standard
are specified from this:
Encode the byte sign_len as follows:
Length of the DU status including the header byte: 04..63
Flags ‘device-related diagnostics’: 00 constant
Encode the byte status_type as follows:
