        Features:

        • One point-to-point channel is paired with a separately selected electrical interface module.
        • ASCII, 3964(R), and printer functions organize serial transfer and message output.
        • Parameter and message-text memory support the configured communication application.
        Siemens 6ES7441-1AA05-0AE0 separates serial processing from the S7-400 CPU program.

        The interface submodule installed in 6ES7441-1AA05-0AE0 defines the cable signals and speed boundary.

        Communication blocks move buffered user data between 6ES7441-1AA05-0AE0 and the controller program.

        The Siemens 6ES7441-1AA05-0AE0 SIMATIC S7-400 CP 441-1 Point-to-Point Communication Module may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

        Replaceable Electrical Interface

        • Module selection: The fitted interface module determines RS232, RS422/485, or 20 mA TTY signaling.
        • Cable assignment: Connector wiring and signal roles follow that interface module rather than the CP base alone.
        • Rate boundary: Each electrical interface has its own documented maximum transmission rate.
        • Replacement check: Record the CP, interface submodule, cable pinout, and partner electrical standard together.

        Serial Transfer Procedures

        • ASCII path: Transparent character transfer uses the configured frame and end criteria.
        • 3964(R) path: Coordinated telegram handling adds control characters and acknowledgements.
        • Printer function: Stored message text and variables can be formatted for a supported printer connection.
        • Unsupported service: RK 512 is not provided by this CP variant and must not be selected in the project.

        Parameters, Texts and CPU Blocks

        • Parameter area: Interface settings occupy the documented parameter-memory range.
        • Text area: Printer messages use the available message-text memory when that function is configured.
        • CPU exchange: Communication blocks and their data areas pass payloads and status between the CPU and CP.
        • Backup scope: Preserve hardware configuration, protocol parameters, message texts, function blocks, and instance data.

        Power and Environmental Checks

        • Backplane supply: The S7-400 rack provides the module logic with the documented DC supply paths.
        • Interface load: The installed interface submodule contributes to current demand and power loss.
        • Temperature: Cabinet conditions must remain inside the operating limit for the complete fitted assembly.
        • Commissioning: Test both transfer directions, status codes, error handling, and printer output where configured.
        Description
        As an S7-400 rack module, Siemens 6ES7441-1AA05-0AE0 is a CP 441-1 communications processor with one point-to-point channel. A separately selected interface module defines whether that channel operates as RS232, RS422/485, or 20 mA TTY hardware.

        Telegram processing in 6ES7441-1AA05-0AE0 uses ASCII, 3964(R), or printer functions according to the loaded configuration. The module handles the serial timing and buffers, then exchanges user data and status with the S7-400 CPU through communication function blocks.

        Parameter and message-text storage inside 6ES7441-1AA05-0AE0 supports the configured interface and printer functions. Required CPU work memory varies with the blocks and data areas assigned to the point-to-point application, so the program and module project must be treated as one installation set.

        Backplane power supplies the logic of 6ES7441-1AA05-0AE0, while the selected interface module determines the external electrical boundary and maximum transmission rate. Replacement therefore requires both the CP order number and the installed interface type to be recorded.

        Technical notes
        The installed interface submodule determines the external serial signals and rate limit of Siemens 6ES7441-1AA05-0AE0, so the CP alone does not define the cable.

        FAQS

        The following is a list of questions commonly asked by our customers. Please contact us if you have a question about our process that is not answered below.
        VIEW ALL FAQS
        Why is the cable type for 6ES7441-1AA05-0AE0 not determined by the CP order number alone?
        The 6ES7441-1AA05-0AE0 uses a separately selected interface submodule, so identify whether RS232, RS422/485, or 20 mA TTY hardware is actually fitted.
        Why can 6ES7441-1AA05-0AE0 reject an RK 512 configuration?
        The 6ES7441-1AA05-0AE0 supports ASCII, 3964(R), and printer functions but does not provide RK 512, so select a documented procedure and matching partner.
        What must be backed up before replacing 6ES7441-1AA05-0AE0?
        Preserve the 6ES7441-1AA05-0AE0 rack configuration, interface-submodule type, serial parameters, communication blocks, instance data, message texts, cable pinout, and partner settings.
        Why can 6ES7441-1AA05-0AE0 send printer text but fail normal data exchange?
        Compare the 6ES7441-1AA05-0AE0 configured function, message-text assignment, communication-block calls, framing, partner protocol, buffer status, and interface wiring.
        How should a low maximum rate on 6ES7441-1AA05-0AE0 be investigated?
        Identify the interface module installed in 6ES7441-1AA05-0AE0 because 20 mA TTY has a lower documented rate limit than RS232 or RS422/485.
        Why can the S7-400 CPU report a CP error after downloading 6ES7441-1AA05-0AE0?
        Verify the 6ES7441-1AA05-0AE0 slot, hardware version, interface-submodule selection, parameter set, communication-block version, addresses, and diagnostic buffer entries.
