Do-more CPUs and Do-more Designer Software / Re: DM2 CPU?

« Last post by BobO on June 26, 2026, 05:15:45 PM »

More memory and a textual subroutine language are in the plan, although I'm really not a fan of ST as the textual language. We'll probably do it, but graybeard languages from the 80s really shouldn't be the focus. A Java/C variant makes better sense for the future and even that starts to become a question when AI enters the picture.

General Discussion / Re: New features wanted!! Apply here!

« Last post by Controls Guy on June 25, 2026, 05:14:30 PM »

• Local variables associated with code blocks and just more name-spacey things in general
• Library support.   TIA portal has a pretty extensive library functionality; you can store almost anything in there, code blocks, configured hardware, entire PLC racks, it's pretty open
• More conventional implementation of SFC
• User symbolic boolean constants
• Add day and date to time display on trends.   I often do trends that span several days.  Right now I have to click a snapshot which includes the date
• My partner will say FBD but don't listen to him
• He also feels like the Simulator could be stronger, I can't figure out what he means.

Any chance we'll get structured text capability in Do-More?
I see that Productivity just got that. I use Do-More/BRX for almost every project, and prefer to keep it that way. But being able to mix and match the existing ladder logic with ST, in different programs and tasks, would be a really useful feature.

Do-more CPUs and Do-more Designer Software / Re: Variable velocity jogging with AXJOG?

« Last post by JasonO on June 19, 2026, 02:43:51 PM »

Another question on this: Along with the dynamic axis velocity while jogging, I also need to implement soft limits to keep the axes from crashing. I think I need to either a: use AXVEL to jog, and every scan calculate at what point I need to stop the jog and ramp to a stop, based on the current velocity, and considering the current acceleration, or b: Use an AXSCRIPT, with a While loop repeating a Ramp to Vel command, until reaching the point where we need to stop, and then transitioning to a Move to Position command, to bring the axis to a stop at exactly the limit of its stroke, or c: use AXVEL and just simply trim the TargetVelocity as I approach the limit, so that it ramps the TargetVelocity to zero by the time the limit is reached.

Not sure I'm thinking through this all correctly. I would prefer to use S-curve accel/decel ramps, so the math gets a bit dense for me. Maybe I'm overcomplicating this too. Just curious if there's any insight from anyone.

Thanks!

Are you able to share any information on any new features/abilities? or even a timeline?

There are several schools of thought on this and we are back and forth on which we are going to do. What things would you like to see?

The things I would like to see in no particular order would be,

• DNP3-SA support
• Profinet support
• More memory for larger UDT types > 64DWords
• Double length tag/nicknames
• More than 1 level of nesting in a UDT
• Structured Text support
• A folder structure to sort/group programs and tasks in the project browser ect. e.g. A program that controls a pump, and calls separate tasks for different functions can be nested underneath

We are based in Australia and our work is mostly with Water Authorities and these are the protocols that they use including Ethernet/IP but that is already supported.
We have already started using a few of the OPCUA poms and so far they have been a great addition but DNP3 is our biggest hindrance in using more BRX.

I understand everyone has different use cases and ours might be the minority but that’s my 2 cents.

Would have to dig in a bit to see what might be happening. There certainly isn't any intentional move to the rail, but we'll need to study the reset state and see what's gong on.

Looks like maybe I need to use AXVEL to achieve this, with the .TargetVelocity dynamically update from the scaled analog value, as log as the instruction is active?

Yes, AXVEL will do what you want.
