5.6.6 Writing Sequence Programs to ROM in CNC
Sequence programs transferred from GX Works2 and built-in PLC (built-in edit function) to the CNC controller are stored in
temporary storage. Data in temporary storage are erased at power OFF. (The sequence programs stored in the ROM in the
CNC is enabled by powering ON the CNC controller again.)
To retain data after the CNC is powered ON again, transfer the sequence programs in temporary storage to the ROM in the
CNC according to the following procedure.
This section describes how to transfer sequence programs in the temporary storage the CNC controller to the ROM in the
CNC on GX Works2.
For the user safety sequence, ROM write operation is not required.
Note
(1) When the sequence programs in temporary storage (RAM in CNC) are updated, but not written to the ROM in the CNC,
"ROM-Write incomplete" error is generated.
