The same procedure is used to either input a program for the first time or to change a program that already exists. In either case, the current contents of Program Memory is overwritten.

The program shown in the following diagram will be entered to demonstrate this operation.

TIM 000
#0123	12.3 s

MOV(021)

#0100

LR 10

ADB(050)

#0100

#FFF6

DM 0000

00201READ NOP (000)

If a mistake was made inputting the instruction, press the Up Arrow Key to return to the previous program address and input the instruction again. The mistaken instruction will be overwritten

To specify the Completion Flag for a timer or counter, press the LD, AND, OR, or NOT Key followed by the TIM or CNT Key, and then input the timer/ counter number last.

6.Input the second instruction and operand. (In this case it isn’t necessary to enter the timer number, because it’s 000.) Press the WRITE Key to write the instruction to Program Memory.
