4-6-2 Entering and Editing Programs
Programs can be entered and edited only in PROGRAM mode.
The same procedure is used to either input a program for the first time or to
edit a program that already exists. In either case, the current contents of Pro-
gram Memory is overwritten, i.e., if there is no previous program, the
NOP(00) instruction, which will be written at every address, will be overwrit-
ten.
To enter a program, input the mnemonic code that was produced from the
ladder diagram step-by-step, ensuring that the correct address is set before
starting. Once the correct address is displayed, enter the first instruction
word and press WRITE. Next, enter the required operands, pressing WRITE
after each, i.e., WRITE is pressed at the end of each line of the mnemonic
code. When WRITE is pressed at the end of each line, the designated in-
struction or operand is entered and the next display will appear. If the instruc-
tion requires two or more words, the next display will indicate the next oper-
and required and provide a default value for it. If the instruction requires only
one word, the next address will be displayed. Continue inputting each line of
the mnemonic code until the entire program has been entered.
When inputting numeric values for operands, it is not necessary to input lead-
ing zeros. Leading zeros are required only when inputting function codes
(see below). When designating operands, be sure to designate the data area
for all but IR and SR addresses by pressing the corresponding data area key,
and to designate each constant by pressing CONT/#. CONT/# is not required
for counter or timer SVs (see below). The AR area is designated by pressing
SHIFT and then HR. TC numbers as bit operands (i.e., completion flags) are
designated by pressing either TIM or CNT before the address, depending on
whether the TC number has been used to define a timer or a counter. To des-
ignate an indirect DM address, press CH/
*
before the address (pressing DM
is not necessary for an indirect DM address).
