Overview
The 6AG1540-1AB01-7AA0 is a Siemens SIPLUS CM PtP communications module for the SIPLUS S7-1500 system, providing RS-422 and RS-485 serial connectivity with conformal coating for extended temperature range. 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.
Features & function
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.
