It runs at up to 19.2 kbit/s over a maximum cable run of 15 m. Cable length is limited to 15 m. The module supports 7 or 8 data bits, 1 or 2 stop bits, and configurable parity. Galvanic isolation is type-tested at 707 V DC between the backplane bus and the interface, so you can safely connect devices operating at different ground potentials without creating ground loops. Power is drawn from the backplane bus (50 mA), so no external supply needed. Diagnostics include LED indication for RUN, ERROR, transmit, receive, and wire-break detection, plus diagnostic alarms that can be evaluated by the CPU. The module supports fast startup and I&M data (I&M 0), making it compatible with TIA Portal's device identification and commissioning workflow. With a current lifecycle stage, this part is built to order through Siemens' normal production pipeline. Lead times are typical for a catalog S7-1500 module — quoted per your delivery requirements through an RFQ. No last-time-buy or end-of-life concerns.","metaTitle":"Siemens 6ES7540-1AD00-0AA0 CM PtP RS-232, 19.2 kbit/s, 127 m","metaDescription":"Active production CM PtP module for S7-1500.
