TRANSMIT with supplementary linear axis
With active TRANSMIT, the channel identifier of posBCS[ax[3]] must have another name in
the parts program, like the geometry axes. If posBCS[ax[3]] is written only outside the
TRANSMIT transformation, this restriction does not apply if the axis has been assigned to a
geometry axis. With active TRANSMIT, no contour information is processed via ax[3].
REPOS
It is possible to reposition on the sub-blocks produced as a result of the extended TRANSMIT
function in SW 4. In this case, the control uses the first sub-block that is closest to the
repositioning point in the BCS.
Block search
In the case of block search with calculation, the block end point (of the last sub-block) is
approached in cases where intermediate blocks have been generated as the result of the
extended functionality in SW 4.
