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 added for the device-spe‐
cific diagnostics data. Of these, the first 4 bytes in the PROFIBUS
®
standard are specified:
Encode the sign_len byte as follows:
Length of the status DU including the header byte: 04..63
‘Device-related diagnostics’ specification: 00 constant
Encode the status_type byte as follows:
Status type: 48 (manufacturer-specific)
‘Status’ specification: 1 constant
Encode the slot_number byte as follows:
Slot number: 0 (because only slot 0 is being used)
