Fig. 8.3-4 Writing data
The active nodes (dispatcher and transceivers) can read the data of
any telegram on the bus (also their own telegrams; separate storage
areas for transmit data and receive data). A maximum of 8 different
telegrams (8 x 32-bit data) can be read. For this purpose, those
addresses and channel numbers whose data are to be read are
parameterized as receive telegrams in the dispatcher or in the
transceivers. This parameterization is carried out before data traffic is
started up; in the case of MASTERDRIVES, for example, via the
parameters of the converter.
