The Event Drum features 16 steps and 16 discrete outputs. Step transitions occur on

timed and/or event basis. The jog input also advances the step on each off-to-on

transition. Time is specified in counts per step, and events are specified as discrete

contacts. Unused steps and events must be left blank. The discrete output points

may be individually assigned.

Whenever the Start input is energized, the drum’s timer is enabled. As long as the

event is true for the current step, the timer runs during that step. When the step count

equals the counts per step, the drum transitions to the next step. This process stops

when the last step is complete, or when the Reset input is energized. The drum

enters the preset step chosen upon a CPU program-to-run mode transition, and

whenever the Reset input is energized.
