During sequence program editing, signal names (symbols) and
comments can be entered for I/O signals, relays, and coils. Easy-to-
understand signal names and comments should be entered to improve
program maintainability.
1.3.4 Transferring and Writing Sequence Program to PMC
After completing editing for the sequence program, input (transfer) the
program to the PMC. This operation is unnecessary when you have
edited the program by using the built-in programmer.
When you have edited the sequence program by using the PC
programmer, input the sequence program from the editing environment
(the personal computer (PC)) to the PMC. The following input
methods can be used:
(1) Input from the I/O screen
For data input, connect the PC containing the sequence program to
the CNC via RS-232C. Alternatively, save the sequence program
from the PC to a memory card, then input the memory card
contents to the PMC.
(2) Input from the online monitor screen
For data input, connect the PC containing the sequence program to
the CNC via Ethernet or RS-232C.
After inputting the sequence program, write it in the flash ROM. This
operation can be done with the DATA I/O screen of the PMC.
