          PRODUCT DESCRIPTION

          One serial connection with the original AA04 interface generation

          Siemens 6ES7441-1AA04-0AE0 is a CP 441-1 communication processor for one serial partner connection in S7-400 systems. A matching IF 963-xAA00 submodule determines the RS232, 20 mA TTY or X27 RS422/485 interface. Its identity and the configured protocol must be checked separately.

          This AA04 processor is limited to 38.4 kbps and provides ASCII, 3964(R) and printer drivers, with restrictions for each physical interface. The faster AA05 rate, later xAA10 submodules and CP 441-2 protocol features do not establish capabilities for this exact model.

          SYSTEM & REPLACEMENT CHECK

          Information needed before ordering

          Three direct checks to secure your system integration and minimize ordering risks.

          System integration Replacement check Manuals & support
          SERIAL PARTNER INTEGRATION

          Match the processor limit, interface module and partner protocol

          Identify the serial communication partner and the installed IF 963 before assigning a cable or protocol. The AA04 CP 441-1 supports one device interface, with RS232, TTY or X27 behavior supplied by the matching xAA00 submodule. The processor identity alone does not establish the offered assembly electrical interface or its cable pin assignment.
          Apply the 38.4 kbps processor limit even when a submodule table shows a higher physical-interface capability. The configured driver, framing and flow-control settings must also agree with the partner. ASCII, 3964(R) and printer functions are documented for CP 441-1, but two-wire RS485 does not support the 3964(R) procedure.
          Integrate the processor through the documented STEP 7 and CP 441 configuration arrangement, preserving the communication program and diagnostics handling. Review the CP current requirement separately from the selected interface-submodule supply requirement. A successful physical connection is not proof of correct data exchange; verify the agreed message handling and transmit, receive and fault status during commissioning.

          Features:

          • AA04 and xAA00 pairing
          • Protocol-specific physical limits
          • Partner data exchange verified
          The Siemens 6ES7441-1AA04-0AE0 requires the documented hardware configuration, installation conditions and interface arrangement to be verified before system integration and commissioning.
          INTERCHANGEABILITY

          Verify the complete replacement identity before commissioning

          Record the full 6ES7441-1AA04-0AE0 marking, installed IF 963 order number and rack position before selecting a spare. Compare the serial standard, configured protocol and partner settings as a single arrangement. The AA05 processor uses a different submodule generation and a higher headline rate, so it is not an unreviewed like-for-like substitution.
          Preserve the project parameters and cable assignment, including the interface-specific termination and shielding requirements. Do not exchange the plug-in interface module under power: Siemens warns of permanent damage and instructs removal of power or removal of the CP from the rack first. Distinguish that restriction from the separate rack-module replacement behavior.
          After fitting the correct processor and submodule, verify parameter loading and actual communication with the intended partner. Check transmit, receive, interface-fault and internal or external fault indications, and read the diagnostic information where required. Confirm the original message format and response handling rather than accepting an illuminated status indicator as complete functional proof.

          Features:

          • Exact CP and IF identities
          • Power-off submodule exchange
          • Protocol and diagnostics confirmation
          The Siemens 6ES7441-1AA04-0AE0 requires replacement verification based on its complete order number, installed hardware, signal configuration and project documentation.

          FREQUENTLY ASKED QUESTIONS

          Questions buyers ask about 6ES7441-1AA04-0AE0

          Direct answers about identity, compatibility, stock, warranty, payment and shipping.

          • Why is the maximum not 115.2 kbps?

            The manual explicitly limits CP 441-1 with order number 1AA04 to 38.4 kbps. The 115.2 kbps figure belongs to other processor variants or the interface-submodule capability and does not override this processor limit.

          • Can an IF 963-xAA10 submodule be fitted?

            The manufacturer assigns xAA00 submodules to AA04 processors and xAA10 submodules to AA05 processors. Their mechanical arrangement differs; do not select a submodule by connector appearance alone.

          • Does this model include RK512 or Modbus drivers?

            The CP 441-1 driver list contains ASCII, 3964(R) and printer functions. RK512 and the cited Modbus functions belong to other CP 441 configurations and are not established as integrated features of this exact processor.

          • Can 3964(R) run on a two-wire RS485 connection?

            No. The interface support table excludes 3964(R) for two-wire RS485. Check the electrical interface and the communication partner before assigning a protocol.

          • Can the serial interface module be exchanged while powered?

            No. Siemens warns that plugging or unplugging the interface submodule under power can cause permanent damage. Remove power or remove the CP from the rack as instructed before changing the submodule.

          • Is the interface-submodule rating the complete assembly rating?

            No. The CP and the chosen IF 963 have separate current, loss, protection and transmission limits. Review both sets of data, and apply the lower relevant communication limit.

          • Does the processor order number identify the supplied connector type?

            Not by itself. The installed IF 963 selects the physical serial standard. Check the actual submodule marking and delivery scope instead of assuming an RS232, TTY or X27 module is included.
