For line A or B connections, use bus segments with t-junctions and
termination blocks to form the PROFIBUS media (trunk cable). Use
termination blocks to terminate the line at each end of the trunk
cable. Use drop cables to connect devices to the network.
The maximum number of stations on the same network is 32.
