Measurement for saving data management frames (measurement type 26)
Saving data management frames ($AC_MEAS_TYPE = 26)
This measurement type offers the option of saving some or all data management frames with
their current value assignments to a file. The measurement can be initiated by executing a
command or via the part program. The function can also be activated from different
channels. The files are set up in directory _N_SYF_DIR.
A Restore operation deletes the backed-up data and a new Save operation overwrites the
existing back-up. The data last saved can then be deleted with
● $AC_MEAS_CHSFR = 0 system frames;
● $AC_MEAS_NCBFR = 0 global basic frames;
● $AC_MEAS_CHBFR = 0 channel basic frames;
● $AC_MEAS_UIFR = 0 number of settable frames
from the data management system using a second Save operation.
Note
If you decide to create a backup of all data management frames, remember that 1 KB of
memory is needed to save each frame. If insufficient memory is available, the process is
aborted with error message MEAS_NO_MEMORY. The required amount of DRAM can be
modified using the following machine data:
MD18351 $MM_DRAM_FILE_MEM_SIZE
