■License key generation
The license key to be written to the Motion CPU is generated in MT Developer2.
Insert the USB key into the USB port of a personal computer, and generate the license key with "Add-on library management"
in MT Developer2. The generated license key is saved in the license key file (license.lky).
■Writing the license key to the Motion CPU
The license key file (license.lky) is written to the Motion CPU via MT Developer2 or SD memory card.
■Checking the add-on library license
For add-on libraries that require a license, the license is checked during the initial processing when the Multiple CPU system
power supply is turned ON. If there is no applicable license key in the license key file, a warning (error code: 0EF1H(details
code: 0101H)) occurs, and a license period is set.
When the license period is exceeded, a moderate error (error code: 3081H), or a minor error (error code: 1FF1H) occurs, and
the add-on library can no longer be used.
■Checking the license authentication information
The add-on library license authentication information can be checked in the license authentication information screen of MT
Developer2.
The status of add-on libraries with checked licenses (period check, license authentication) can be checked. Add-on libraries
provided free of charge are not displayed.
License authentication method
The license authentication method is different depending on the status of the license purchase, and whether the Motion CPU
can be connected online or not.
The following is the license authentication procedures.
: Use a personal computer with USB key inserted, : Use MT Developer2 or an SD memory card
