Siemens 6ES5752-0AA23 is a SIMATIC S5 interface module designed to provide a V.24/V.28 (RS‑232C) serial interface for use with the CP 524 communications processor and the CPU 928B. Used within S5 PLC systems, it enables straightforward integration of RS‑232 based communication into an automation setup, supporting reliable data exchange between the controller and compatible external devices. This module is supplied as an interface module for CP 524/CPU 928B applications where a standard RS‑232 serial connection is required.

What does this interface module do?
It provides a serial communications interface for selected SIMATIC S5 systems, enabling a CP 524 communications processor or a CPU 928B to communicate via a V.24/V.28 (RS‑232C) style interface.
Which SIMATIC S5 components is it intended to work with?
It is intended for use with the SIMATIC S5 CP 524 and the SIMATIC S5 CPU 928B, providing the relevant V.24/V.28 serial interface connection.
What serial standard does it use?
It supports V.24/V.28, which corresponds to RS‑232C for serial communication in industrial control environments.
Is it suitable for RS‑232 connections to external devices?
Yes. Because it is a V.24/V.28 (RS‑232C) interface module, it is commonly used to connect the S5 communication hardware to RS‑232 compatible equipment such as terminals, printers, modems or serial-capable measurement devices (subject to the overall system’s communication capabilities).
What is the difference between V.24 and V.28 in practical terms?
In many industrial contexts they are referenced together because they relate to the electrical signalling and interface characteristics associated with RS‑232 type serial links. This module is specified for V.24/V.28 (RS‑232C) usage.
Where is the module used within an S5 system?
It is used as an interface module associated with the CP 524 communications processor or the CPU 928B, enabling the required serial interface for communication tasks.
What types of applications typically use this module?
Typical uses include serial data exchange between an S5 controller and peripheral or supervisory equipment, such as basic data logging, device parameter read/write over serial, and integrating legacy serial instruments into an S5-based control system.
Does it convert RS‑232 to RS‑485 or RS‑422?
No. This unit is specified for V.24/V.28 (RS‑232C). RS‑422/RS‑485 conversion would require a different, dedicated interface solution.
Can it be used with a CPU 928B for serial communications?
Yes. It is specified as an interface module for the CPU 928B using V.24/V.28 (RS‑232C) signalling.
Is this module considered a spare part within the S5 range?
Yes. It is commonly supplied and referenced as a spare part for maintaining and sustaining installed SIMATIC S5 systems; you may see it listed as Siemens 6ES5752-0AA23 in technical documentation and inventories.
What should I check to confirm it is the correct module for my installation?
Confirm the target hardware is a CP 524 or CPU 928B and that the required interface is V.24/V.28 (RS‑232C). Also verify the existing serial cabling and connector expectations in your panel match the RS‑232 style interface used by your setup.
- Enabling RS‑232C (V.24/V.28) serial communications for Siemens SIMATIC S5 systems using a CP 524 communication processor
- Providing a serial interface connection for S5 installations built around the CPU 928B where a V.24/V.28 link is required
- Integrating legacy S5 PLC control racks with external serial devices that communicate via RS‑232 signalling
- Supporting point-to-point data exchange between an S5 controller and peripheral equipment through a dedicated serial channel
- Adding a V.24/V.28 communications path to existing S5 panels and cabinets during upgrades, retrofits, or system expansions
- Restoring serial connectivity in established S5 installations where the original interface module has failed or been removed
- Facilitating serial data acquisition and reporting from an S5 system to third-party instrumentation or supervisory equipment using RS‑232 protocols
- Enabling configuration and commissioning workflows that rely on an RS‑232 physical layer on CP 524/CPU 928B-based systems
