    Communication Communication is of greater importance in wide area installations. The AC 31 system possesses other interfaces, apart from the CS 31 bus, adapted to different communication modes. This chapter presents, in particular, the interfaces available with the 40 and 50 series central units which possess three communication protocols on the same serial interface (Figure 7-1).
