Determining The Path Tangent In Synchronized Actions - Siemens SINUMERIK 840Di sl Function Manual

Data Backup
System variables $AC_MARKER and $AC_PARAM saved in SRAM can be included in the
data backup.
The following backup modules are present for each channel:
_N_CHi_ACM
_N_CHi_ACP
i denotes the relevant channel number.
Sequence
The saved modules are entered in the full backup file _N_INITIAL_INI according to R
parameters.

Determining the path tangent in synchronized actions

$AC_TANEB
The system variable $AC_TANEB (Tangent ANgle at End of Block), which can be read in
synchronized actions, calculates the angle between the path tangent at the end of the
current block and the path tangent at the start of the programmed following block.
The tangent angle is always output positive in the range 0.0 to 180.0 degrees. If there is no
following block in the main run, the angle -180.0 degrees is output.
The system variable $AC_TANEB should not be read for blocks generated by the system
(intermediate blocks). The system variable $AC_BLOCKTYPE is used to tell whether it is a
programmed block (main block).
Programming example:
ID=2 EVERY $AC_BLOCKTYPE==0 DO $R1 = $AC_TANEB;
