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).
