6.3.10 Notes on Starting Up the IP247 Positioning Module via the PC Interface

if you startup the positioning module via the PC interface, the system identification (SYSID) must
be transferred to the module before the machine data are transferred. After power up, the follow-
ing defaults are set:
—
slot number
— page number
The machine data can then be transferred to the module, Only machine data with a module num-
ber (DLn+3 of the machine data DB) identical to the module number in the SYSID (DRn+6 or
DRn) are permitted.
If the machine data are valid, the axis can be moved in the JOG mode or incremental relative
mode. Absolute targets can only be approached after calibration of the axis (mode 5).
There is no "overwrite mode" for machine data. If an axis requires new machine data, the follow-
ing operations must be carried out:
— transfer the "new" machine data record to the axis via the page assigned to it (BA20).
You can assign any permitted DB number to a machine data record on the I P247 (DBO to
machine data records to the axes is made using the axis number in the machine data record
however, with a different axis number (=> Section 4.3.12 "Enter Machine Data" or Section
4,3.13 "Delete Machine Data"), For more information about machine data, refer to Section 2.5
"Machine Data and their Structure".
A maximum of 255 machining programs (DBO to DB255) can be stored on the positioning mod-
ule. An existing machining program cannot be overwritten. If you wish to modify a machining pro-
gram stored on the IP247, then a certain procedure must be adhered to, just as with the machine
data:
unless it already exists there (BA 69),
A machining program is not restricted to an axis. All three axes can execute the same machining
program simultaneously. Machining programs can only be transferred and deleted via the data
channel (4th page). A machining program can, however, only be deleted when no other axis is
using this machining program (=> Section 4.3.17 "Executing Machining Programs"). For more
information about machining programs, refer to Section 2.6 "Machining Programs and their Struc-
ture".
