7.3.6
Evaluation of internal drive variables
Note
This function is under license and is not available with version T/M value.
If the corresponding option is activated without a valid license, alarm 8081 "%1 option(s) that
has (have) not been licensed using a license key was (were) set" is output. It will not be
possible to operate the machine as normal.
For information on operations relating to "Setting (an) option(s)", please refer to the section
titled "Licensing in SINUMERIK 802D sl" in the "Turning, Milling, Grinding, Nibbling"
Operating Instructions.
Function
To ensure that the internal drive variables are available for evaluation in the NC, these are
transferred from the drive as additional process data (PDA) during cyclic PROFIBUS
communication and saved by the operating system in system variables.
The additional PDA is part of standard telegram 116.
