Using All Functions with
Direct
LOGIC PLCs
When configuring the OP-1212, a base address must be selected in the CPU. This
address can be a
direct
mapping to the reserved memory locations that are tied to
internal relays. The internal relays of
Direct
LOGIC PLCs (DL05, DL06, DL105,
DL205, DL350 and DL405) start at
V40600
. Using this method, the total mapping
consumes 96 internal relays, which 75 are assigned to operator functions. This
method is only used when all of the OP-1212 functions are utilized. In the examples
below,
V40600
has been chosen as the starting address for
Direct
LOGIC PLCs.
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 X12 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 X13 is activated Lamp 5 will turn ON and when
contact X14 is activated the Lamp will flash.
Rungs 5 and 6 -- Flashing LEDs
To flash an LED, it must first be turned ON. When
contact X15 is activated, LED 1 will turn ON and when
contact X14 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 Y10 is started.When the
process is completed, it activates contact X16 which forces
pushbutton 12 OFF.
NOTE: The pushbuttons must be configured as maintained
(alternate) and the panels ”Force Function” feature must be enabled.
