Entering applied instructions
Programming applied instructions in GX Works2 FX is simple. Just position the cursor in the
place in the program line where you want to insert the instruction and type the abbreviations for
the instruction and its operand(s). GX Work2 will automatically register that you are entering
an instruction and will open the input dialog (see below). Alternatively, you can also position the
cursor and then click on the insert instruction tool in the toolbar
You can also select the instruction from the
drop-down list, which you can display by
clicking on the " " icon.
Then enter the abbreviations for the instruction and its operand(s) in the input field, separating
them by spaces.
All numbers must be preceded by a letter character, which either identifies the device type or –
in the case of constants – specifies the number format. The letter "K" identifies decimal con-
stants and "H" identifies hexadecimal constants.
Help

applied instruction into the program.
If you are programming in Instruction List format enter the instruction and its operand(s) in a
single line, separated by spaces.
