More Information

Overview Manuals License Scope Target CPs Languages Setup Checks

Features:

  • One hardware dongle authorizes a single MODBUS Master V3.1 installation.
  • The licensed communication function targets SIMATIC CP 341 and CP 441-2 processors.
  • STEP 7 V4.02 or later provides the supported engineering environment for the project.
Siemens 6ES7870-1AA01-0YA1 supplies the license and hardware dongle for one MODBUS Master V3.1 installation.

The communication processor used with 6ES7870-1AA01-0YA1 carries the serial exchange while the licensed blocks control MODBUS master requests.

Project recovery for 6ES7870-1AA01-0YA1 depends on retaining the dongle, license record, STEP 7 project, and target CP configuration.

The Siemens 6ES7870-1AA01-0YA1 SIMATIC S7 MODBUS Master V3.1 Single License with Hardware Dongle 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.

Single-Installation Authorization

  • License count: The supplied right covers one installation rather than a floating multi-station pool.
  • Dongle: The hardware dongle carries the physical authorization required by the licensed installation.
  • Class: The software is supplied under the documented Class A license category.
  • Delivery boundary: Separate installation media and printed documentation are not included under this article number.

Communication Processor Roles

  • CP 341: The S7-300 communication processor provides the serial interface used by the MODBUS master function.
  • CP 441-2: The S7-400 communication processor is the other documented target for the licensed blocks.
  • Serial path: The selected CP wiring and interface mode must match the connected MODBUS slave network.
  • Project assignment: The software blocks and hardware configuration must reference the installed CP and its configured channel.

Installed Software Language Set

  • German: German operator and installation text is included in the documented language set.
  • English: English software text is available for engineering and service work.
  • French: French is the third documented software language.
  • Project language: Language selection does not change the MODBUS telegram structure or CP wiring.

Project Restoration Boundaries

  • STEP 7 version: The engineering station must meet the documented V4.02-or-later requirement.
  • Operating system: The documented software environment includes Windows XP and Windows 7.
  • License match: The installed dongle and license record must belong to the same single installation.
  • Commissioning: CP parameters, block calls, slave addresses, framing, and telegram mapping must be tested together.
Description
Siemens 6ES7870-1AA01-0YA1 is a SIMATIC S7 MODBUS Master V3.1 runtime software license delivered with a hardware dongle. It authorizes one installation that uses the supported communication blocks with a CP 341 or CP 441-2 module.

The control program associated with 6ES7870-1AA01-0YA1 exchanges MODBUS master requests through the selected communication processor rather than through the dongle itself. The CP handles the physical serial channel while the licensed software supplies the protocol function for the configured S7 project.

Installation of 6ES7870-1AA01-0YA1 requires the supported STEP 7 environment and the matching project components because the order scope does not include separate software media or printed documentation. The license class, dongle, target CP, and MODBUS project must therefore be verified together before a system is restored.

Technical notes
Siemens 6ES7870-1AA01-0YA1 licenses one MODBUS Master V3.1 installation; the dongle, STEP 7 project, and CP 341 or CP 441-2 must match.

Can 6ES7870-1AA01-0YA1 authorize several engineering stations at the same time?
No. 6ES7870-1AA01-0YA1 is a single license for one installation, so each separate licensed station requires its own valid entitlement.
Why does a restored project still reject the 6ES7870-1AA01-0YA1 license?
Verify that the 6ES7870-1AA01-0YA1 hardware dongle is present, recognized by the supported system, and assigned to the restored installation.
Which communication processors are documented for 6ES7870-1AA01-0YA1?
The documented targets for 6ES7870-1AA01-0YA1 are the SIMATIC CP 341 and CP 441-2 communication processors.
What should be backed up before moving a 6ES7870-1AA01-0YA1 project?
Preserve the 6ES7870-1AA01-0YA1 dongle, license record, STEP 7 source project, communication blocks, CP parameters, and MODBUS address mapping.
Why can 6ES7870-1AA01-0YA1 be installed but still exchange no MODBUS data?
Check the 6ES7870-1AA01-0YA1 target CP, serial wiring, interface mode, baud rate, framing, slave address, block calls, and error status.
Does the 6ES7870-1AA01-0YA1 order scope include separate software media?
No. The 6ES7870-1AA01-0YA1 delivery is identified as a license with hardware dongle without separate software media or documentation.
