1. Turn on Bits 0, 5, and 6 of DM1676 ($0061) to enable changing the screen between the
operator, switch comment, and lamp comment screens.
2. With the MEMSW instruction, turn on SW3-3 of the memory switch ($0800) to set the 24-
bit high-speed counter.
3. Set the high-speed counter in double multiplication mode and reset high-speed counter
0.
4. High-speed counter 0 starts when relay 1000 is turned on. Customized lamp 1 illuminates
while the high-speed counter is operating.
5. The ON/OFF status of relay 1000 is switched every time customized switch F1 is
pressed. (Alternating circuit)
6. The current value of high-speed counter 0 and the outputs of comparators 0 and 1 are
reset when customized switch F2 is pressed.
7. Customized lamp 2 illuminates when comparator 0 turns on.
8. Customized lamp 3 illuminates when comparator 1 turns on.
9. A flicker circuit is used to flash the titles.
When relay 1000 is turned on, assign relay 15000 to the device displayed on the first line
(specify "#55000" in DM1580), and set the attributes so that only the comment is dis-
played (Bit 8: ON) (DM1680 = $0100). Continue this operation for 500 ms.
After 500 ms, assign relay 15001 to the device displayed on the first line (specify
"#55001" in DM1580), and set the attributes so that only the comment is displayed (Bit 8:
ON) (DM1680 = $0100). Continue this operation for 1 second.
Repeat the operations above to flash the title.
10. Assign CTH0 to the device displayed on the second line (specify "#23000" in DM1581).
Set the attributes so that the decimal point position is "2" ($0002), the number of spaces
at the right end is "2" ($0020), a sign is used (Bit 9: ON), and changing the value is
disabled (Bit 15: ON) (DM1681 = $8222).
