5.13 DNC OPERATION
General
In DNC operation, automatic operation is performed by reading a
program from an external I/O device through the interface.
When a floppy-type external I/O device (such as a Handy File, Floppy
Cassette, or FA Card) is connected, the user can select the programs to
read, and specify an execution sequence and the number of times
automatic operation is to be performed.
Before DNC operation can be performed, the communication settings
must be made on the communication setting screen. For details of the
communication settings, see Section 9.17 in Part II.
