Master Frame Types
Overview
9.1.11.1
The frame type describes the different configuration of frames. Some of the frame types are only for specific purpose,
which will be defined in the following subsections. The master request frames are issued by the LCU and provide
address information for the connected slave. The slave will receive every master request frame and compare the
address information to its reference address stored in the OTP. If the address issued by the master matches the slave
reference address, the slave takes action according the master request frame; otherwise the entire frame will be
ignored.
When setting up a network it has to be taken care that all slaves connected to the network are assigned a unique
address to avoid bus collisions. One particular slave address is used to implement a broadcast synchronization
feature, which will cause all connected slaves to change their duty cycle output control configuration at the same
point in time.
The data transfer from the LCU to the slave is organized in dedicated master request frames, namely
