DP Slaves Connectable to a Y Link
Configuration example
S An S7-300 with a CPU 315-2DP as an I slave with various I/O ranges
S Two SIMODRIVE 611U with two axes each, PPO Type 5
S One heating control HS 724

The actual hardware configuration of the station is irrelevant here. The only factor that
counts are the I/O ranges that are transparent to the H system.
Thus, the maximum frame length for the input data and output data has been
reached for the underlying DP master system. No additional slaves can be
operated on this DP master system.
