Create a simple program using the program loader. The sample program performs the following operation:
When input I0 is turned on, output Q0 is maintained.
When input I1 is turned on, output Q1 is maintained.
When input I2 is turned on, both outputs Q0 and Q1 are reset.
Set the RUN/STOP switch on the program loader to STOP. This will stop the MICRO

operation.
Delete the entire program from the program loader.
Make a time chart, relay diagram, and program list to perform the intended operation.
Enter the program by pressing the keys on the program loader. If you make a mistake in the key sequence, press the CLR
key to begin the current line of programming (current address) again.
Check the program from address 0 to the end of the program using the

Press the CLR key three times to read address 0.
Press the key to verify the program up to the last address.
