Operation Keys; Instruction Keys - Omron SYSMAC C Series User Manual

Using the programming console
Operation keys
These yellow keys are the ones you'll use to carry out the editing functions
of the programming console. These functions will be explained in more
detail later but at this point it's important that you know how three in
particular are used.
The first two are the arrow keys. When you want to move through your
program a step at atime, you press the bottom (down) arrow key. The
displayed address of the program will increment once for each press. To
go the opposite direction, press the other (up) key. The program will
decrement one step at a time until it reaches its beginning.
The arrow keys are normally used for moving only a small number of
steps in the program. Later we'll show you several ways to move right to
the program step you want.
The third key in the yellow group you should know about now is the WRITE
key. During programming when you have written an instruction and its
data, use this key to register the instruction in the PC memory at the
address desired.
Instruction keys
Except for the SHIFT key on the upper right, these gray keys are the ones
you'll use to place instructions in your program. The SHIFT key is similar
to the shift key of a typewriter, and is used to obtain the second function of
those keys that have two functions.
