6.8.3 RS-485-A interfaces
Several participants can communicate via the RS-485-A bus at which the
maximum number of participants is limited to 32. The wires to other partici-
pants have to be shielded. For participants with lower unit load than as-
sumed by the standard (e.g. 1/4 unit load), more than 32 participants can be
connected.
