Accumulator / Stack Load and Output Data Instructions
Load Address
The Load Address instruction is a 16 bit
(LDA)
instruction. It converts any octal value or
address to the HEX equivalent value and
LDA
loads the HEX value into the accumulator.
O aaa
This instruction is useful when an address
parameter is required since all addresses
for the DL105 system are in octal.

on when the value loaded into the accumulator by any instruction is zero.
NOTE: Two consecutive Load instructions will place the value of the first load
instruction onto the accumulator stack.
In the following example when X1 is on, the octal number 40400 will be converted to
a HEX 4100 and loaded into the accumulator using the Load Address instruction.
The value in the lower 16 bits of the accumulator is copied to V2000 using the Out
instruction.

Accumulator Logic Instructions
Or Double
The Or Double is a 32 bit instruction that
(ORD)
ors the value in the accumulator with the
value
(Aaaa), which is either two
ORD
consecutive V memory locations or an 8
K aaa
digit
(max.) constant value. The result
resides in the accumulator. Discrete
status flags indicate if the result of the Or
Double is zero or a negative number (the
most significant bit is on).

Encode
The Encode instruction encodes the bit
(ENCO)
position in the accumulator having a value
of 1, and returns the appropriate binary
ENCO
representation. If the most significant bit is
set to 1 (Bit 31), the Encode instruction
would place the value HEX 1F (decimal
31) in the accumulator. If the value to be
encoded is 0000 or 0001, the instruction
will place a zero in the accumulator. If the
value to be encoded has more than one bit
position set to a “1”, the least significant “1”
will be encoded and SP53 will be set on.

Bit Operation Instructions
Decode
The Decode instruction decodes a 5 bit
(DECO)
binary value of 0-31 (0-1F HEX) in the
accumulator by setting the appropriate bit
DECO
position to a 1. If the accumulator contains
the value F (HEX), bit 15 will be set in the
accumulator. If the value to be decoded is
greater than 31, the number is divided by
32 until the value is less than 32 and then
the value is decoded.
In the following example when X1 is on, the value formed by discrete locations
X10-X14 is loaded into the accumulator using the Load Formatted instruction. The
five bit binary pattern in the accumulator is decoded by setting the corresponding bit
position to a “1” using the Decode instruction.

The Move instruction moves the values
(MOV)
from a V memory table to another
V memory table the same length. The
MOV
function parameters are loaded into the
V aaa
first level of the accumulator stack and the
accumulator
by
two
additional
instructions. Listed below are the steps
necessary to program the Move function.
S Step 1:— Load the number of V memory locations to be moved into the
first level of the accumulator stack. This parameter is a HEX value (K40
max, 100 octal).
S Step 2:— Load the starting V memory location for the locations to be
moved into the accumulator. This parameter is a HEX value.
S Step 3:— Insert the MOVE instruction which specifies starting V
memory location (Vaaa) for the destination table.
Helpful Hint: — For parameters that require HEX values when referencing memory
locations, the LDA instruction can be used to convert an octal address to the HEX
equivalent and load the value into the accumulator.

S Step 1:— Load the number of words to be copied into the second level
of the accumulator stack.
S Step 2:— Load the offset for the data label area in ladder memory and
the beginning of the V memory block into the first level of the stack.
S Step 3:— Load the source data label (LDLBL Kaaa) into the
accumulator when copying data from ladder memory to V memory. Load
the source address (LDA Oaaa) into the accumulator when copying data
from V-memory to ladder memory. This is the source location of the

Interrupt
The Interrupt instruction allows a section of
(INT)
ladder logic to be placed below the main
body of the program and executed only
INT
O
when needed. High-Speed I/O Modes 10,
20, and 40 can generate an interrupt. With
Mode 40, you may select an external
interrupt
(input X0), or a time-based
interrupt (5-999 mS).
Typically, interrupts are used in an application when a fast response to an input is
needed or a program section must execute faster than the normal CPU scan. The
interrupt label and all associated logic must be placed after the End statement in the
program. When an interrupt occurs, the CPU will complete execution of the current
instruction it is processing in ladder logic, then execute the interrupt routine. After
interrupt routine execution, the ladder program resumes from the point at which it
was interrupted.
See Chapter 3, the section on Mode 40 (Interrupt) Operation for more details on
interrupt configuration. In the DL105, only one interrupt is available.

Interrupt Return
An Interrupt Return is normally executed as
(IRT)
the last instruction in the interrupt routine. It
returns the CPU to the point in the main
IRT
program from which it was called. The
Interrupt Return is a stand-alone
instruction (no input contact on the rung).
Enable Interrupts The Enable Interrupt instruction is placed in
(ENI)
the main ladder program (before the End
instruction), enabling the interrupt. The
ENI
interrupt remains enabled until the program
executes a Disable Interrupt instruction.
Disable Interrupts A Disable Interrupt instruction in the main
(DISI)
body of the application program (before
the End instruction) will disable the
DISI
interupt
(either extenal or timed). The
interrupt remains disabled until the
program executes an Enable Interrupt
instruction.

Interrupt Instructions
In the following example, we do some initialization on the first scan, using the
External Interrupt
first-scan contact SP0. The interrupt feature is the HSIO Mode 40. Then we
Program Example
configure X0 as the external interrupt by writing to its configuration register, V7634.
See Chapter 3, Mode 40 Operation for more details.
During program execution, when X2 is on the interrupt is enabled. When X2 is off the
interrupt will be disabled. When an interrupt signal (X0) occurs the CPU will jump to
the interrupt label INT O 0. The application ladder logic in the interrupt routine will be
performed. The CPU will return to the main body of the program after the IRT
instruction is executed.

The Fault instruction is used to display a
(FAULT)
message on the handheld programmer or
in the DirectSOFT32 status bar. The
FAULT
message has a maximum of 23 characters
A aaa
and can be either V memory data,
numerical constant data or ASCII text.
To display the value in a V memory location, specify the V memory location in the
instruction. To display the data in ACON (ASCII constant) or NCON (Numerical
constant) instructions, specify the constant (K) value for the corresponding data
label area.

NOTE: The FAULT instruction takes a considerable amount of time to execute. This
is because the FAULT parameters are stored in EEPROM. Be sure to consider the
instructions execution times (shown in Appendix C) if you are attempting to use the
FAULT instructions in applications that require faster than normal execution cycles.
Fault Example
In the following example when X1 is on,
the message SW 146 will display on the
handheld programmer. The NCONs use

Drum Instruction Programming
Introduction
Purpose
The Event Drum (EDRUM) instruction in the F1-130 CPU electronically simulates
an electro-mechanical drum sequencer. The instruction offers enhancements to the
basic principle, which we describe first.
Drum instructions are best suited for repetitive processes that consist of a finite
Drum Terminology
number of steps. They can do the work of many rungs of ladder logic with elegant
simplicity. Therefore, drums can save a lot of programming and debugging time.
We introduce some terminology associated with the drum instruction by describing
the original mechanical drum shown below. The mechanical drum generally has
pegs on its curved surface. The pegs are populated in a particular pattern,
representing a set of desired actions for machine control. A motor or solenoid rotates
the drum a precise amount at specific times. During rotation, stationary wipers sense
the presence of pegs (present = on, absent = off). This interaction makes or breaks
electrical contact with the wipers, creating electrical outputs from the drum. The
outputs are wired to devices on a machine for On/Off control.
Drums usually have a finite number of positions within one rotation, called steps.
Each step represents some process step. At powerup, the drum resets to a
particular step. The drum rotates from one step to the next based on a timer, or on
some external event. During special conditions, a machine operator can manually
increment the drum step using a jog control on the drum’s drive mechanism. The
contact closure of each wiper generates a unique on/off pattern called a sequence,
designed for controlling a specific machine. Because the drum is circular, it
automatically repeats the sequence once per rotation. Applications vary greatly, and
a particular drum may rotate once per second, or as slowly as once per week.
Pegs
Wipers
Drum
Outputs
Electronic drums provide the benefits of mechanical drums and more. For example,
they have a preset feature that is impossible for mechanical drums: The preset
function lets you move from the present step directly to any other step on command!
