More Information

Overview Manuals Interface Modules Protocol Handling STEP 7 Configuration Diagnostics

Features:

  • Two serial channels accept plug-in interface modules for different electrical standards.
  • ASCII, 3964(R), RK512 and printer drivers are supplied in the communication processor.
  • Traffic and fault LEDs separate channel activity from internal and external alarms.
The two channels on 6ES7441-2AA04-0AE0 can be equipped independently with the documented RS232, 20mA TTY or X27 interface module required by each partner.

Protocol processing occurs in 6ES7441-2AA04-0AE0, while STEP 7 assigns the rack slot and address used by the S7-400 CPU to reach the communication processor.

The 115.2 kbit/s limit for 6ES7441-2AA04-0AE0 applies to the summed transmission rate of its two interfaces, so channel settings must be considered together.

The Siemens 6ES7441-2AA04-0AE0 SIMATIC S7-400 CP 441-2 Communication Processor may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

All prices are shown in USD.

Choosing the physical layer for each serial channel

  • RS232 option: An RS232 plug-in module gives one channel of 6ES7441-2AA04-0AE0 the corresponding point-to-point electrical interface.
  • Current-loop option: The 20mA TTY module adapts a channel to a current-loop communication partner.
  • Differential option: The X27 module supplies RS422/485 electrical behavior.
  • Channel independence: The two positions can be populated according to the two connected partners rather than requiring identical interface modules.

How frames move between the serial partner and S7-400

  • Character traffic: The ASCII driver on 6ES7441-2AA04-0AE0 transfers serial character streams with configured framing.
  • Handshake procedure: 3964(R) adds a defined control-character exchange around transmitted blocks.
  • Computer link: RK512 organizes addressed data exchange with the communication partner.
  • Printer output: The printer driver formats controller data for a connected serial printer.

Connecting the rack entry to protocol parameters

  • Rack entry: 6ES7441-2AA04-0AE0 is placed in the STEP 7 hardware table with its rack, slot and order number.
  • Address assignment: STEP 7 assigns the address through which the S7-400 CPU reaches the processor.
  • Protocol setup: The CP 441 configuration package supplies the parameter interface for the selected serial protocol.
  • Driver loading: This AA04 version permits customer-specific transmission drivers to be loaded with the configuration package.

Separating traffic indications from fault sources

  • Transmit state: TXD indicators on 6ES7441-2AA04-0AE0 show data leaving the corresponding serial channel.
  • Receive state: RXD indicators show data arriving from the connected partner.
  • Interface fault: FAULT indication identifies a problem associated with the serial interface.
  • Group alarms: INTF and EXTF LEDs distinguish internal processor faults from external conditions.
Description
Siemens 6ES7441-2AA04-0AE0 is a SIMATIC S7-400 CP 441-2 communication processor that establishes point-to-point data exchange between the controller and external programmable controllers or computers. Two serial device channels distinguish this CP 441-2 from the one-channel CP 441-1.

Each channel of 6ES7441-2AA04-0AE0 receives a plug-in interface module selected for RS232, 20mA TTY or X27 RS422/485 electrical behavior. The interface module defines the physical connection, while the communication processor firmware handles ASCII, 3964(R), RK512 or printer protocols.

In the S7-400 rack, 6ES7441-2AA04-0AE0 is entered in the STEP 7 hardware configuration so the CPU can address the processor in its assigned slot. TXD and RXD indicators show channel traffic, while FAULT, INTF and EXTF indicators separate interface faults from internal and external group alarms.

Technical notes
Siemens 6ES7441-2AA04-0AE0 uses two plug-in serial interface positions so the CP 441-2 can match RS232, 20mA TTY or RS422/485 partners.

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.
How should the two interfaces on 6ES7441-2AA04-0AE0 be matched to field devices?
Fit each channel of 6ES7441-2AA04-0AE0 with the RS232, 20mA TTY or X27 RS422/485 module required by that channel's communication partner.
Does 6ES7441-2AA04-0AE0 provide 115.2 kbit/s independently on both channels?
No. For 6ES7441-2AA04-0AE0, 115.2 kbit/s is the summed maximum transmission rate across the two interfaces.
Which protocol choices are already available in 6ES7441-2AA04-0AE0?
The supplied firmware of 6ES7441-2AA04-0AE0 includes ASCII, 3964(R), RK512 computer-link and printer drivers.
Why must the exact AA04 version be selected when configuring 6ES7441-2AA04-0AE0?
STEP 7 uses the exact order number of 6ES7441-2AA04-0AE0 for the rack entry, and its aggregate channel-rate and driver-loading behavior differ from the AA05 version.
What do the front indicators reveal when 6ES7441-2AA04-0AE0 stops communicating?
TXD and RXD on 6ES7441-2AA04-0AE0 show channel traffic, while FAULT, INTF and EXTF separate interface, internal and external fault conditions.
