The Do-more Designer software is a free download.
To test your program, use the built-in simulator or connect to a Do-more PLC with your choice of a serial, USB or Ethernet connection.
The built-in simulator creates a virtual PLC so you can test your logic without a PLC present.
The Do-more instruction set was developed by listening to our customers' needs and requests, with flexibility and ease of use as our goals. Download the free software today and take a look at these powerful and easy-to-use instructions.
The spreadsheet style MATH instruction allows mixing of data types* and it accepts formulas and variables. The MATH instruction also allows nesting with parentheses up to 8 levels, plus:
If that's not enough, how about absolute value, time, memory, and indirect addressing? You even get access to system-level bits such as $IndexError, $OutOfRange, $Overflow, etc.
* Note about data types: integer and real types are really all you need but Do-more does include a few BCD and octal conversion instructions for legacy data types.
Dedicated instructions greatly simplify and improve the motion functionality of Do-more PLCs.
View Trend Data in its own view and within specific ladder instructions like PID, RAMPSOAK, and High/Low Alarm.
Tasks and Programs can be suspended to isolate code; stages can be enabled or disabled.
The PID Monitoring window allows precise tuning of your PID loops.
Use the Data View to monitor program elements and Program Status Bits for behind-the-scenes visibility into PLC internal operations.
Strong data typing keeps your data organized and protected. Data structures automatically put the important details at your fingertips.
Do-more can be as flexible as you need. You can allocate all the data memory the way you want it up to specific maximums (no more rigid, predefined blocks of wasted space!).
You can even define your custom memory addresses and assign a data type of your choice to improve the readability of your program.
Do-more supports straight ladder logic, tasks, subroutines, and stage structures for a best-of-all-worlds approach that simplifies code and makes troubleshooting easier.
Code can be broken up into Programs, Tasks, Subroutines and Interrupt Service Routines:
Code blocks can be suspended to isolate code; stages can be enabled or disabled.
Get flexible, powerful control over your program code execution:
All project files are stored on board the CPU - no more searching for the old laptop with the most recent copy of the program before you can fix your machine!
You can also store your own files with the disk-based version of the project to aid future improvement or troubleshooting efforts. Store PDF, HTML or virtually any file format (up to 10Mb) that you want to keep with the project for reference, or information to assist your coworkers or customers whenever they open the project.
The Project Browser makes it easy to select the code block you want to view or edit. System tasks are predefined for many common actions. Jump directly to any part of your code with just a few clicks.
The Do-more Designer software even supports "restore points", which are basically previous versions of your program that you saved at known good operation. It's nice to know that you can easily "roll back" your project if your development goes awry.
Do-more Designer can download a new version of your code into the Do-more CPU and seamlessly switch to it at the beginning of the next scan. There is no need for any pause (however brief) that can wreak havoc on the operation of your machine or process.
