Tips & Tricks
C-more tag import
To easily get your tags from a Do-more! Designer Project into a C-more HMI, in Do-more! Designer go to
File –> Export -> Element Documentation. Pick C-more Do-more! Driver Format WITH Structure Fields.
If you want C-more to reference elements that are used in your ladder program but do NOT have nicknames,
you can either assign them nicknames, or you can check the “Also export USED elements which do not have
a nickname” in the Export Element Documentation dialog box.
Pointers, Indexing and Arrays
In order to utilize a memory element as an array, it must be a Memory Block. Heap Items are singeltons and
cannot be utilized as an array. To see what elements can be used as an array or to create a custom item, go to
System Configuration -> Memory Configuration -> Memory blocks tab.
Addressing a Memory Block as an array is simple. Place brackets [ ] after the Memory Block name and use
a V memory element such as V0 as the index. IE D[V0], N[V5], UDT[V0], etc.
A handy trick for knowing how large the array is without hardcoding values is to use the DATAINFO
instruction.
Bit of Word, Data type conversion and Casting
Getting bits out of a word in Do-more! Designer is done with a method called Casting. More information
on Casting can be found in Do-more! Designer Help Topic DMD0309.
The basics of Casting a memory element are to use a “:” and an identifier or for Bit of Word, a number. IE
D0:1 is bit 1 of memory element D0. All Bits start at zero.
To simplify Casting, you can use the Cast Builder. When on a field that supports a memory element, press
the F9 key. Type your Source Element in the appropriate field and then in the bottom right corner, press the
“Show Cast Builder” button. Click the appropriate radio buttons and then press “Select”. It is that easy to
cast a memory element.
Other methods for doing memory type conversion is by using the ladder commands PUBLISH and
SUBSCRIBE. These will allow you to convert large areas of memory at once which is useful when you are
talking to a Modbus or DirectLogic device that utilizes untyped memory.
Formatting Date and Time on an HMI with String Scripting
If you want your date and time to look nice on your HMI, put the data into a string using STRPRINT and
the string scripting language. See Do-more! Designer Help Topic DMD0168 for a list of all string scripting
commands.
MATH, Logical Operations & statistical functions
The Do-more! MATH instruction is a very powerful feature. Do-more! Designer Help Topic DMD0085
covers the lists of functions that are available.
In addition to doing Arithmetic and Trigonometry, it can also do Logical and Bitwise operations. A few
minutes perusing this help topic can save you a lot of time.

The most common issue when doing Math with a Do-more! processor is knowing that you must promote the
equation to Real (Floating Point) if you are using integers with a Real result. If the equation is integers, but
you wish to have a result that is a Real number you must use TOREAL() or add a decimal point to one of the
numbers; IE 2.0. See Help topic DMD0085 for more information on promoting numbers to Real format.
Simulation and PID Simulation
Do-more! Designer software comes with a separate Do-more! simulator application that runs the same
Do-more! control engine that is in the Do-more! CPUs. You can connect/disconnect and upload/download
to the simulator as you would with a Do-more! CPU. There is even a Run/Term/Stop mode switch and LED
indicators for power, Run and communication activity. This is a great tool to test your code before you ever
load it into your system.
The Simulator also has the ability to do simple PID simulation to learn how PID works!
See Do-more! Designer Help Topic DMD0234 for more information.
Symbolic Constants
Do-more! Designer supports the use of Symbolic Constants. A Symbolic Constant is where you assign a
nickname to a hard coded value. IE Sunday = 0, Monday = 1, Tuesday = 3, etc. Do-more! Designer Help
topic DMD0276 has more information on symbolic constants.
To assign a Symbolic Constant, go to Tools -> Documentation Editor and then press the “Symb” in the
toolbar of the Documentation Editor tab. This can help make your program much easier to read and
navigate.
You can add a nickname to a memory location that has a cast. For example you have a double word signed
number in D100 nicknamed “Dancer” for your dancer position. If you wanted to know that it was a negative,
you could use D100:31 which is the sign bit for D100. If you were to nickname D100:31 “Dancer_Neg”
you could use this nickname throughout your program and it would always refer to D100:31.
Start Page replacement
You can attach documents to your project to replace the content of the Start Page on a project-by-project
basis. This can be a PDF, Excel spreadsheet, .JPG, etc. A good example of this is the PID1.dmd example
project found in the Examples folder in Do-more! Designer.
Moving Communications links to another PC
You can move your communications links from one PC to another by copying the DmDComm.RST file that
is located in the Do-more\Designerx_x\Bin\ folder.
Troubleshooting email with DMLogger
In your Do-more! Designer ladder project, turn $EnableMsgDump bit ON & start Do-more! Logger from
Applications window in the Launchpad to troubleshoot email. This will send the server messages to your PC
so that you can see exactly where it is getting stuck at.
The DMLogger utility can also be useful for troubleshooting by placing STREAMOUT instructions in your
ladder code to send messages to the utility to let you know what is happening at various times.

Importing Program segments
Use the #import mechanism in your Import Program text file so you can modularly create projects from
different source files. So MyProject.TXT could contain just 4 lines:
#include “SysConfigXYZZY.txt”
#include “MachineControl.txt”
#include “Library\NonLinearControlLibrary.txt”
#include “Library\CalendarLibrary.txt”
Keyboard Shortcuts
The following table lists the keystrokes (also known as Hot Keys or Accelerator Keys) available in the various
views of Do-more! Designer that can greatly enhance the usability of each view.
