1.9.2 Logging via CP315 with the SINUMERIK 840/880
The following data are output in the program header after the measuring data
determined above.

• Transfer parameter for measuring point No. (4 digits) (R45)
The measuring point number can be generated in two ways, either automatically by the
PLC or from parameter R45.
Note:
If the measuring point number is defined via R45 the measuring results must only be entered
in R parameters R200-R219. Bit 7 must be set in cycle machine data 7000 (only enter result in
R200-R219).
Which method is used is determined in parameter R39 with the command for output of the
log header before the measurement results are logged. Once the desision has been made
with log header output, change between automatic measuring point specification by the
PLC and manual preselection by the part programmer is no longer possible.
With manual preselection, R45 must precede each measuring circle call.
The measuring point number has a total of 6 digits. The 4 left digital places are the actual
measuring point number.
– Submeasuring point No. (decimal point and 1 decimal place)
The submeasuring point No. is used to designate suplementary lines whenever several
measurements are to be made at one measuring point. How many submeasuring
points of a measurement are to be logged is defined in R39. Submeasuring points
must always be logged in ascending sequence and without a gap.
The assignment of the submeasuring point No. to a particular axis or function is made
by the user.
The base line contains data of the diameter measured, the 1st supplementary line data
of the horizontal axis and the 2nd supplementary line data of the particular axis when
Siemens measuring cycles and submeasuring points are used. Further supplementary
lines are not needed at present.
• Examples of parameter assignment
– Log output, basic line
R39=111102x0 Identification parameter
x= 2 ... 3
R39=11110220 must be assigned for logging a measuring point. If a tolerance
violation of the setpoint is detected after the measurement, the relevant measuring
point can be given the identifier R39=11110230. The setpoint difference is marked
with a special character.
