Because it is run from standstill, the spindle orientation at the beginning of the "Rigid Tapping"
cycle is always executed in the direction of rotation that reaches the target by the shortest route.
Previously the direction of rotation with each spindle orientation was selected by marker M2656.

New functions:

If the PLC simultaneously issues two commands from memory areas PLC positioning (M2704 to
M2708), confirm Q parameter (M2713) and PLC datum shift (M2716), then the NC flashes the
message "Error in PLC program 1R" as these commands use the same memory areas for data
transfer.
PLC positioning in more than one axis counts as a single command. If marker M2719 (switch-over
from word processing to TNC 355 mode) has the value 0, the same checks will be run with the
corresponding TNC 355 strobes.
