A-B SLC Pulse Bit
Does A-B SLC 500 PLC have any 1 second bits or 0.5 second bits? I'm using a dos version programming software, I can't find it.

If you need EXACTLY 0.5 or 1 second, you'll have to roll your own with a timer or two. If you're just flashing a light or something, you can use the S:4/0 through S:4/15 bits:
S:4/0 - 20ms
S:4/1 - 40ms
S:4/2 - 80ms
S:4/3 - 160ms
S:4/4 - 320ms
S:4/5 - 640ms
...and so on. I won't bother typing them all. Notice the sequence?...
These clock bits operate at a 50% duty cycle. For example, S:4/0 is ON for 10ms, and OFF for 10ms.
