8.3.2.33 RD_74_PARAM
With this function the parameter string 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.
8.3.2.34 RD_74_ID
With this function the ID string of a slave according to profile S-7.4 is read. Becau-
se 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.
