It supports both PROFIBUS DP and MPI protocols, with automatic baud rate detection from 9.6 kbit/s up to 12 Mbit/s. ## Bus topology and node limits A single segment supports up to 32 stations; the full network can address 126 nodes, of which up to 99 can be EM 277 modules. The RS-485 interface handles cable runs from 100 m to 1200 m, with the maximum distance depending on the selected transmission speed. Node addresses are set via rotary switches on the module face, covering 0 to 99. One connection is reserved for OP communication and one for PG communication, leaving up to four free for data exchange with the DP master.","metaTitle":"Siemens 6ES7277-0AA22-0XA0 PROFIBUS DP Slave Module","metaDescription":"Siemens 6ES7277-0AA22-0XA0 PROFIBUS DP slave module for S7-200.
