I would like to see a "Keep Window on Top" feature implemented. Where you could keep the simulator and/or the Data window open on top of the Ladder window. I use this feature frequently with RSLogix. It's a great tool, especially while working online.

Didn't work.  The ISR is giving timeslices of 50,000us +/- a few us, but it's still giving bad info.  We're going to abandon this sensor and change to a completely different layout.  The accelerometer will still be used for spike measurement though.

This analog sensor is not part of the recall.

If you are referring to the PDF flowchart of the CTRIO2, the source of that information is me. I created flowcharts for all the major functions of the CTRIO/CTRIO2. You can download the charts from the CTRIO FAQ0054. To go there, go to our website (hosteng.com), in the left pane, click on FAQs, then select the CTRIO/CTRIO2 as the product, then scroll down to CTRIO FAQ0054.

It's a great help, and I want to know if you can point to the source of these content.

What information did you study from which source helped me?

It's a great idea. The problem is space. The worst case element name is 22 characters, plus the worst case number value, 11 or more. That breaks everything.

DirectSoft actually replaced the element with the status value, and the way we do it in DmD was a creative way to get both things in the same space, without breaking the displays. When we go to 32 character tag names, we're probably just gonna have to bite the bullet and rethink some stuff.

Well that really did not help. Tried editing the DmDesigner2_2.ini in the windows directory directly because the batch file opens the file in the wrong directory. But I did final edit the right file with NotePad++ which is an excellent text editor. The NotePad replacement. I changed the font size and that was like zooming in every thing. Not good. Tried changing the Status Font and the same not good.
I was thinking of if you were to move the element name to a different position like in the pic below, then all the text would be the same font size.

First page of the module config has a number of channels setting. You probably are set to 8, which means you are getting samples at ~45ms, well over the 2ms you would prefer.

Promotion, not conversion. For instance 1/3 = 0, but 1.0/3 or 1/3.0 = 0.33. When you start mixing integer and float, be sure you are getting promotion to float as required.

Yes, I've definitely seeing decimal places and using toreal() when dividing by a fixed value.  (e.g. the 1,000,000 us to timeslice conversion)  I'm rounding to hundredths digit of acceleration, because anything smaller than that is going to just be the vibration on the desk.   


That could easily come back to sample rate and aliasing effects. I should have asked this before, but have you disabled all channels you aren't using? Assuming that you have, you are sampling each channel ~6ms apart, so there will always be a disconnect between the two inputs. Additionally, since you are sampling each channel at ~11ms (plus 1/2 PLC scan on average) if the sample window shifts relative to the movement you are capturing, where the accel move is captured right at the leading edge, but the decel is captured 10ms delayed from the start, the sum of each half won't cancel. It probably won't ever, but the tighter the sample window the better the chance it's close.

I've only got the two channels on, the rest are tied to ground.  Aren't they disabled by default?  I didn't set any of them up in the System Configuration except for the ones that I'm using (RX0 and RX1)   

Ohhh, I have an idea.  I'm going to try waiting for the timeslices to get longer than the minimum sample time, but use the variable length from the tickus() and see where that goes.  If that doesn't work I'm going to mail the parts to someone I don't like.
