Do-more CPUs and Do-more Designer Software / Re: Feature request: Search available in Trend View

Maybe add 4, 12, and 24 hours or something?   There's plenty of screen real estate to make the slider longer without making the detents narrower in pixels.   I do really long trends a lot.

Oh, would also like the slider for trend width to go wider than an hour (24 hours maybe?).   You can set the width to whatever you want in the dialog, but if you zoom in with the slider, you cen't get back to longer without the dialog again.

The detents are completely up to us.  Completely non-linear.  I widened that whole control for 2.11, so to add (at least) 2 more detents is very do-able.

Is there any way to add more Remote I/O? the 16 limit seems low. If you use some edrv100's you lose out pretty fast.

Use Modbus instead of native?   Not sure if the Modbus scanner is limited to 16 server/slaves, but I doubt if MRX/MWX is.

Do-more CPUs and Do-more Designer Software / Use of LVDT for closed loop feedback versus rotary Encoder

« Last post by opburg89 on July 23, 2026, 08:29:15 PM »

Good afternoon,
Is there any information for using an LVDT transducer with a 4-20mA analog output signal instead of a standard rotary style encoder for the closed-loop feedback
for a single Axis setup configured within Do-more? It appears if I'm reading correctly that you need to use a standard pulsed rotary encoder for the position/velocity feedback input?
The application we are using it on has a Hydraulic cylinder with an integrated 4-20mA LVDT transducer analog feedback and the cylinder is being controlled by a +/-10vdc
hydraulic proportional valve. Thanks in advance!

I like it!   Or a right click on the element/nickname on the left or right vertical axis (might be iffy since for analogs those move vertically with the pen)

It sure would be nice to be able to connect USB devices into the BRX. One thing I always wished that I could connect was a USB based barcode reader. I'm assuming that there must be some good reason why you guys never developed this capability.

There seems to be a limit of 1024 bytes associated with various "processes", STREAMIN comes to mind as one example. You can only download 1024 bytes each time that instruction is run. STRPRINT might be another example. Are you giving any thought to increasing the size to any of these?

USB mastering requires different hardware and lots of driver support. It isn't trivial if you don't have a OS. We choose not to have an OS to reduce the hack risk.

The 1024 limit is internal buffering. That would be be easy to increase with our next hardware.

Today, I would have searched for an item I was trending and hoped to find occurrences in logic.

Yes!  If the current Trend View has just one element, it can definitely do a Find All on that one.  There's actually a hot key Ctrl+Shift+Y for Find All (Current Element).

If the current Trend View has more than one element (more typical?), we could prompt with a drop-down list of all the elements in the current trend view, then perform the Find All.
