You may see some similarities to the
DirectLOGIC PLC instruction set. However, the
instruction set for the Do-more PLC is more
advanced and intuitive. A good example is the
MATH instruction. Now, just one MATH
instruction covers all math operations and
also allows you to mix different data types in
one expression.
There are over 60 operators and functions
available with the MATH instruction.
Note: To learn more about the MATH instruction, please refer to the Do-more Designer
help topic ‘MATH – Calculate Expression’.

Do-more T1H Series PLC Overview
Data Types
The Do-more PLC supports the following seven primary data types:
• Bit (0 or 1)
• Unsigned Byte (0 to 255)
• Signed Byte (-128 to 127)
• Unsigned Word (0 to 65,535)
• Signed Word (-32,768 to 32,767)
• Signed DWord (-2,147,483,648 to 2,147,483,647)
• Real (-3.4028235E+038 to 3.4028235E+038)
Data Structures
The Do-more PLC supports data structures as additional data types. Structures use the
familiar PC programming organization of “dot notation”. All available elements of a
structure are shown in this format. The following data structures are currently available:
• Timer Structure
• Counter Structure
• String Structure
• PID Structure
• Date/Time Structure
• Task Structure
• Rampsoak Structure
• Program Structure
• DeviceRef Structure
• Drum Structure
• Stream Structure
• SIM_Process Structure
• Server Structure
• Peerlink Structure
• I/O_Master Structure
• Eth_IO_Master Structure
• GS Drive Structure
• Packet Structure
The data structure is a set of data. For instance, a Timer structure (Timer Struct) has the
following set of data:
• Acc (Accumulated Time, Signed DWord)
• Done (Bit)
• Zero (Bit)
• Timing (Bit)
• Reset (Bit)
When you use a timer instruction (TMR), a Timer structure is assigned to the instruction.
If you select ‘T0’, you can access the above data with dot notation. For instance, to
access the accumulated time (Acc), enter ‘T0.Acc’. To access the Done bit, enter
‘T0.Done’.
Memory Addressing
With the Do-more PLC, each memory address type has its own specific data type. Here
are some examples:
• V (Unsigned Word)
• N (Signed Word)
• D (Signed DWord)
• R (Real)
If you see address ‘V123’ in the ladder program, the memory address always stores an
Unsigned Word value. With this memory addressing method, it becomes easier to read
and write the ladder programs.
Although most of the memory addressing is decimal, the memory addresses DLX, DLY,
DLC and DLV use octal. These four memory address types can be used to exchange data
with DirectLOGIC PLCs, which use octal memory addressing.

Array Addressing
The Do-more PLC supports one-dimensional array addressing with all memory
addresses. A V-memory address must be used as the index for an array. With the
Do-more PLC, the following ladder program is valid.

Code-block, Program and Task

Controls
One Do-more project can consist of more than one ladder program. Each ladder
program is called a ‘Code-block’. The Do-more PLC supports two types of code-blocks,
Program and Task:
Proximity
Sensors
Program

Sensors
Programs are code-blocks that run based on an event using the RUN instruction. They
can be self-terminating or never terminate. Stage programming is only supported inside
Program code-blocks.
Limit
Switches
Task
Encoders
Tasks are code-blocks that are enabled and disabled using the ENTASK instruction. The
ENTASK instruction allows you to specify an interval to execute the task’s logic with a
millisecond resolution or to execute a single time on a leading edge input.

Stages
The Do-more PLC supports Stages. You can use Stages only in the Program code-blocks.
(They are not available in the Task code-blocks.) The Do-more PLC supports the following
instructions for Stage Programming1:

• SGDIVRG (Jump to Multiple Stages)
