Basic function principles
With a TwinCAT 3 license dongle, the TwinCAT 3 license is independent of the IPC used, since all required TwinCAT 3 licenses are bound to the TwinCAT 3 license dongle.
On the IPC the so-called LicenseResponseFile contains the licenses that are valid for this system. If the LicenseResponseFile also lists the check against a TwinCAT 3 license dongle, TwinCAT searches for the TwinCAT 3 license dongle and checks the following requirements:
- whether it is a Beckhoff device
- whether it is a specific Beckhoff device
After successful checking the licenses are available according to the LicenseResponseFile.
The EP6070-0060 has a local memory so that one or more LicenseResponseFiles can be stored and transported on the TwinCAT 3 license dongle.
Please note that, as an EtherCAT master, TwinCAT checks the complete name of the EtherCAT device during startup, i.e. EP6070-0060 or EL6070-1234 (as an example). A corresponding ESI must therefore exist in the TwinCAT system.
 | Firmware Update The firmware on the EP6070-0060 cannot be updated. The ESI revision can be updated, if necessary. |
| Warranty The hardware used in the EP6070-0060 represents a very high hurdle for possible attacks according to the present level of knowledge. In general, cryptographic systems may not be continually safe against all conceivable attacks. Encryption security is therefore not covered by the guarantee for the product. |
Operating hours counter
The EP6070-0060 has a non-erasable operating hours counter in the CoE parameter 0xF900:01 in the unit [sec], which counts when the supply voltage US is applied.
