- Description
The Siemens 6AV6671-8XE00-0AX0 is an RS-422 to RS-232 converter that screws directly onto a SIMATIC HMI's 9-pin male RS-422 interface and presents a 9-pin female RS-232 port for connecting a third-party PLC. The cable outlet exits at 180 degrees, and the small 31 x 50 x 11 mm housing weighs just 26 g.

Selection Notes
Pick this converter when a third-party PLC only offers an RS-232 port but the SIMATIC HMI's serial interface is RS-422 - it screws straight onto the panel's port rather than requiring a separate cable run, and the 180-degree cable outlet keeps the connector low-profile against the enclosure. Tighten the mounting screws to the specified 0.18-0.2 N.m; the datasheet notes that over-torquing can damage the connector shell.
