It occupies one standard slot (35 mm wide) and requires 127 mm of cabinet depth. Power is drawn from the backplane bus at 0.6 W typ. Transmission rate reaches 115.2 kbit/s with support for 7 or 8 data bits, 1 or 2 stop bits, and configurable parity. The extended address area (1 to 65535) and 4-wire full-duplex connection make it suitable for multi-drop RS-422 networks. An 8 kbyte telegram buffer handles larger messages without host intervention.","metaTitle":"Siemens 6ES7541-1AB00-0AB0 CM PtP Module, 115.2 kbit/s, S7-1","metaDescription":"Active production serial CM PtP module for S7-1500.
