Drum Instruction
The DL05 drum instructions may be programmed using DirectSOFT or for the
EDRUM instruction only you can use a handheld programmer (firmware version
v1.8 or later. This section covers entry using DirectSOFT for all instructions plus the
handheld mnemonics for the EDRUM instruction.
The Timed Drum with Discrete Outputs is the most basic of the DL05’s drum
instructions. It operates according to the principles covered on the previous pages.
Below is the instruction in chart form as displayed by DirectSOFT.

Output Pattern
f= Off, F= On
The Timed Drum features 16 steps and 16 outputs. Step transitions occur only on a
timed basis, specified in counts per step. Unused steps must be programmed with
“counts per step” = 0 (this is the default entry). The discrete output points may be
individually assigned as X, Y, or C types, or may be left unused. The output pattern
may be edited graphically with DirectSOFT.
Whenever the Start input is energized, the drum’s timer is enabled. It 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.
