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
