This module is in active production and supports protocols including freeport, 3964(R), and USS at baud rates up to 19200 bit/s. ## Applications As a SIPLUS CM PtP module it provides point-to-point serial communication for SIPLUS S7-1500 controllers in extreme environments such as chemical plants, oil and gas facilities, and outdoor installations requiring extended temperature tolerance. The module handles RS-422 and RS-485 serial connections via a 15-pin D-sub socket, supporting protocols like freeport, 3964(R), and USS for communication with drives, HMIs, and other serial devices. Conformal coating protects against moisture and contaminants, and the -40 to 70 °C operating range suits deployment in unheated cabinets or outdoor enclosures.","metaTitle":"Siemens 6AG1540-1AB01 SIPLUS CM PtP RS422/485 -40 to +70°C | aoctrl","metaDescription":"Siemens 6AG1540-1AB01-7AA0 SIPLUS CM PtP RS422/485 for ET 200SP: -40 to +70°C, Modbus RTU, 3964(R).
