Product details

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.

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.

Frequently asked questions

What is the 6AG1540-1AB01-7AA0 Siemens SIPLUS CM PtP module used for?

Buyers need to confirm it fits their serial communication role in an S7-1500 system before purchase.

Is the 6AG1540-1AB01-7AA0 an RS-422 or RS-485 communication module?

Determining the electrical interface is critical to matching field devices and wiring.

Does the 6AG1540-1AB01-7AA0 support freeport and USS protocols?

Protocol support determines compatibility with drives, instruments, and legacy serial devices.

What is the difference between 6AG1540-1AB01-7AA0 and 6AG1540-1AB01-2AA0?

Engineers must distinguish the SIPLUS (harsh-environment) variant from the standard variant to avoid mis-specification.

What is the operating temperature range of the 6AG1540-1AB01-7AA0 SIPLUS module?

The -40 to 70 °C range with conformal coating is the key reason to choose this SIPLUS variant.

Where can I buy the 6AG1540-1AB01-7AA0 with current stock and price?

Sourcing buyers need verified availability and pricing to proceed with procurement.
