WR_74_75_PARAM
Description:
• with this function the parameter string of a slave according to profile S-7.4 is be-
ing written
or
• the data tranfer with a slave according to profile S-7.5 is started.
If it is about a slave according to profile 7.5, data have to be registered into the buff-
er in the same form, as they have to be sent by AS-i.
Since the string can be longer than the command interface, it will partly be written
into the buffer and then be transferred to the slave.
n is the length of the part of the string which should be written into the buffer from
index i on.
If i ≡ 0, then the string is being transferred to the slave.
