Contrologix system variables

The processor clock breaks down time all the way down to microseconds. You could use the microsecond DINT bits for a flasher or use a periodic task.

Beyond that I am not aware of specific flash bits like the SLC 500 has. Typically I have just used a timer on delay with a GEQ instruction. Not as accurate as the periodic task, but for a flasher, accuracy was not usually a big concern.
