Keystrokes
Enter an EAF (like Figure 16.14) by performing the following steps.
1. Enter the Examine On and Get instructions.
2. Press [Shift] [EAF].
3. Enter the appropriate function number (Table 16.A).
4. Enter the data and result addresses.
5. Enter the set values. The clock stops when you are setting any of the
three functions.
Time
Time is displayed in military format. For example: 15:00 hours is 3:00pm.
0AA 0BB 0CC
0AA = hours (00 – 23)
0BB = minutes (00 – 59)
0CC = seconds (00 – 59)
Word format for Set and Read Time functions is the same. The only
difference between the two EAFs is their function number: Set Time is 10
and Read Time is 15.
Enter EAF rungs like those shown in Figure 16.15.
