Using All Functions with the DL305 PLCs
When configuring the OP-1212, a base address must be selected in the CPU. This
address can be a
direc
t mapping to the reserved memory locations that are tied to
internal relays. The internal relays of the DL305 family start at
R16
. Using this
method, the total mapping consumes 96 internal relays, of which 75 are assigned to
operator functions. This method should only be used when all of the OP-1212
functions are utilized. In the examples below,
R16
has been chosen as the starting
address for the DL305.
Notice that the internal control relays are numbered in octal
and not decimal.

Rung 1 -- Pushbuttons and Lamps
When pushbutton 7 is activated, Lamps 3 and 4 turn ON.
Rung 2 -- LEDs
When contact IO12 is ON, LED 9 turns ON.
NOTE: Panel must be in LED Separation mode and
pushbutton configured as momentary.
Rungs 3 and 4 --Flashing Lamps
To flash a Lamp, it must first be turned ON When contact IO13
is activated Lamp 5 will turn ON and when contact IO14 is
activated the Lamp will flash.
Rungs 5 and 6 -- Flashing LEDs
To flash an LED, it must first be turned ON. When contact
IO15 is activated, LED 1 will turn ON and when contact IO14 is
activated the LED will flash.
NOTE: Panel must be in LED Separation mode and
pushbutton configured as momentary.
Rungs 7 and 8 -- Force Function
When pushbutton 12 is pressed, process IO0 is started.When the
process is completed, it activates contact IO16 which forces
pushbutton 12 OFF.
NOTE: The pushbuttons must be configured as maintained
(alternate) and the panels ”Force Function” feature must be enabled.
