8.3.2.35 RD_74_DIAG
With this function the diagnosis string of a slave according to profile S-7.4 is read.
Because the string can be longer as the mailbox, it is written into the buffer. The
content of the buffer can read in parts from index i.
The first byte of the bufferis the length of the read string.
If i ≡ 0, then the string is read from the slave, otherwise the function responses out
of the memory, trough which the data can be read consistently.
8.3.2.36 Get_LPS, Get_LAS, Get_LDS, Get_Flags (GET_LISTS)
With this call, the following entries are read out of the AS-i/PROFIBUS Gateway:
• The list of active AS-i slaves (LAS)
• The list of detected AS-i slaves (LDS)
• The list of projected AS-i slaves (LPS)
• The flags according to the AS-i slave specification
