Enter Machining Program (Mode 22)

face. C0M247 uses mode 22 indirectly if you press the corresponding function key. If you trans-
fer a machining program from the CPU to the IP247, FBI 65 must be assigned parameters as
described in Section 6.3 "Standard Function Block FBI 64".
The structure of machining programs is described in Section 2.6 "Machining Programs and their
Structure".
Since machining programs are not axis-related, they are transferred to the module via the data
channel (4th page of the module).
Machining programs are stored one after the other in the memory of the I P247 in the order in
which they are entered, A maximum of 255 machining programs can be stored on the module.
The total number of characters is limited to 6000.
Requirements for the transfer of machining programs areas follows:
the machining program number must not exist on the IP247. It is not possible to overwrite
a program from the PC side. The old program must be deleted first with BA23 ("delete ma-
chining program"),
there must be adequate space in the machining program memory of the IP247. (See notes
in Section 4,3.19, "Delete Machining Program").
If you wish to execute a machining program after it has been created in the CPU, proceed as fol-
lows:
create a machining program in DIN representation with CC) M247. Fill in the input values
with blanks up to the maximum number of input characters (token characters). Having
done this, it is easy to change the machining program in the CPU at a later time,
transfer the machining program to the IP247,
read the machining program with mode 69 using FB1 65,
The program structure is now set in the CPU data block. You can modify individual parameters in
the ASCII format.
delete the machining program on the I P247 with FBI 65,
enter the machining program to the IP247 using FBI 65 with mode 22.
