Boolean Instructions
The DL105 Micro PLCs usually can complete an operation cycle in a matter of
Immediate Boolean
milliseconds. However, in some applications you may not be able to wait a few
milliseconds until the next I/O update occurs. The DL105 PLCs offer Immediate
input and outputs which are special boolean instructions that allow reading directly
from inputs and writing directly to outputs during the program execution portion of
the CPU cycle. You may recall that this is normally done during the input or output
update portion of the CPU cycle. The immediate instructions take longer to execute
because the program execution is interrupted while the CPU reads or writes the I/O
point. This function is not normally done until the read inputs or the write outputs
portion of the CPU cycle.
NOTE: Even though the immediate input instruction reads the most current status
from the input point, it only uses the results to solve that one instruction. It does not
use the new status to update the image register. Therefore, any regular instructions
that follow will still use the image register values. Any immediate instructions that
follow will access the I/O again to update the status. The immediate output
instruction will write the status to the I/O and update the image register.

base and stores the status in an input

Boolean Instructions
There are limits to what you can enter with boolean instructions. This is because the
DL105 internal CPU uses an 8-level stack to evaluate the various logic elements.
The stack is a temporary storage area that helps solve the logic for the rung. Each
time you enter a STR instruction, the instruction is placed on the top of the stack. Any
other instructions on the stack are pushed down a level. The And Store and Or Store
instructions combine levels of the stack when they are encountered. Since the stack
is only eight levels, an error will occur if the CPU encounters a rung that uses more
than the eight levels of the stack.
The following example shows how the stack is used to solve boolean logic.

the rung (on/off) and outputs the discrete

Multiple Out instructions referencing the same discrete location should not be used

Timers are used to time an event for a desired length of time. The single input timer
Using Timers
will time as long as the input is on. When the input changes from on to off the timer
current value is reset to 0. There is a tenth of a second and a hundredth of a second
timer available with a maximum time of 999.9 and 99.99 seconds respectively. There
is a discrete bit associated with each timer to indicate that the current value is equal
to or greater than the preset value. The timing diagram below shows the relationship

There are those applications that need an accumulating timer, meaning it has the
ability to time, stop, and then resume from where it previously stopped. The
accumulating timer works similarly to the regular timer, but two inputs are required.
The start/stop input starts and stops the timer. When the timer stops, the elapsed
time is maintained. When the timer starts again, the timing continues from the
elapsed time. When the reset input is turned on, the elapsed time is cleared and the
timer will start at 0 when it is restarted. There is a tenth of a second and a hundredth
of a second timer available with a maximum time of 9999999.9 and 999999.99
seconds respectively. The timing diagram below shows the relationship between the

Current Values: Counter current values
are accessed by referencing the
associated V or CT memory locations*.
The V-memory location is the counter
location + 1000. For example, the counter
current value for CT3 resides in V memory
location V1003.
Discrete Status Bit: The discrete status
bit is accessed by referencing the
associated CT memory location. It will be
on if the value is equal to or greater than the
preset value. For example the discrete

With each off to on transition of the clock input, the bits which make up the shift
register block are shifted by one bit position and the status of the data input is placed
into the starting bit position in the shift register. The direction of the shift depends on
the entry in the From and To fields. From C0 to C17 would define a block of sixteen
bits to be shifted from left to right. From C17 to C0 would define a block of sixteen
bits, to be shifted from right to left. The maximum size of the shift register block
depends on the number of available control relays. The minimum block size is 8
control relays.

temporary storage location for data that is being copied or manipulated in some
manor. For example, you have to use the accumulator to perform math operations
such as add, subtract, multiply, etc. Since there are 32 bits, you can use up to an
8-digit BCD number. The accumulator is reset to 0 at the end of every CPU scan.

Since the accumulator is 32 bits and V memory locations are 16 bits the Load Double

digit BCD constants to copy data either to the accumulator from a V-memory
address or from a V-memory address to the accumulator. For example if you wanted
to copy data from V2000 and V2001 to V2010 and V2011 the most efficient way to

Accumulator / Stack Load and Output Data Instructions
Using the
The accumulator stack is used for instructions that require more than one parameter
to execute a function or for user defined functionality. The accumulator stack is used
Accumulator Stack
when more than one Load instruction is executed without the use of an Out
instruction. The first load instruction in the scan places a value into the accumulator.
Every Load instruction thereafter without the use of an Out instruction places a value
into the accumulator and the value that was in the accumulator is placed onto the
accumulator stack. The Out instruction nullifies the previous load instruction and
does not place the value that was in the accumulator onto the accumulator stack
when the next load instruction is executed. Every time a value is placed onto the
accumulator stack the other values in the stack are pushed down one location. The
accumulator is eight levels deep (eight 32 bit registers). If there is a value in the
eighth location when a new value is placed onto the stack, the value in the eighth
location is pushed off the stack and cannot be recovered.

Using Pointers
Many of the DL105 series instructions will allow V-memory pointers as a operand
(commonly known as indirect addressing). Pointers allow instructions to obtain data
from V-memory locations referenced by the pointer value.
NOTE: DL105 V-memory addressing is in octal. However, the pointers reference a
V-memory location with values viewed as HEX. Use the Load Address (LDA)
instruction to move an address into the pointer location. This instruction performs the
Octal to Hexadecimal conversion automatically.
In the following simple example we are using a pointer operand in a Load instruction.
V-memory location 2000 is being used as the pointer location. V2000 contains the
value 440 which the CPU views as the Hex equivalent of the Octal address
V-memory location V2100. The CPU will copy the data from V2100 which in this
example contains the value 2635 into the lower word of the accumulator.
