4.2.4 RD_74_75_ID

With this function the ID string of a slave according to profile S-7.4 or the 16-bit

slave configuration according to profile 7.5 is being read. Since the string can be

longer than the command interface, it is written into the buffer. The content of the

buffer can read in parts from index i.

The first byte of the buffer is the length of the read string.

If i ≡ 0, the string is being read from the slave, otherwise the function responses

out of the memory, the data can be read consistently.

By a 7.5 slave is the request always 1. The response byte contains the cyclic 16-

bit slave configuration according to S-7.5 profile (analog/transparent bits are can-

celled). If the response is 08

, that means that the cyclic 16-bit configuration could

not be detected.
