The module draws 35 mA from the backplane bus and dissipates 0.6 W. ## RS232 capabilities and diagnostic coverage Transmission rate tops out at 115.2 kbit/s with configurable parity, stop bits, and character length (7 or 8 bits). The full set of RS232 auxiliary signals — RTS, CTS, DTR, DSR, RI, DCD — is available, so the module handles hardware handshake with older terminals and printers. Diagnostic alarm and wire-break detection are included; the yellow LEDs for RxD and TxD give immediate line-status visibility at the panel. I&M data (I&M 0) is supported for identification and maintenance record keeping. Dimensions: 147 mm × 35 mm × 127 mm. The module has an 8-byte input address area and supports extended addressing up to 65535, with fast startup capability.","metaTitle":"Siemens 6AG1541-1AD00-7AB0 SIPLUS CM PtP RS232, -40 to 70°C","metaDescription":"Active RS232 module for S7-1500, extended temp -40 to 70°C, diagnostic alarms, I&M data.
