FN 29: PLC: Transfer values to the PLC
The FN 29: PLC function transfers up to eight numerical values or
Q parameters to the PLC.
Increments and units: 0.1 µm or 0.0001°
Example: Transfer the numerical value 10 (which means 1 µm or
0.001°) to the PLC

FN 37: EXPORT
You need the FN 37: EXPORT function if you want to create your
own cycles and integrate them in the TNC. The Q parameters 0
to 99 are effective only locally. This means that the Q parameters
are effective only in the program in which they were defined. With
the FN 37: EXPORT function you can export locally effective Q
parameters into another (calling) program.
The TNC exports the value that the parameter has at
the time of the EXPORT command.
The parameter is exported only to the presently
calling program.
Example: The local Q parameter Q25 is exported
56 FN37: EXPORT Q25
Example: The local Q parameters Q25 to Q30 are exported
56 FN37: EXPORT Q25 - Q30
