Do-more CPUs and Do-more Designer Software / Re: BX-08AD-3 not detected by CPU

« Last post by franji1 on March 16, 2026, 09:15:05 AM »

Do you have Manual I/O Configuration enabled?  (Modules configured manually show up, but then get reported as missing if they are not actually there)

Are you re-mapping your discrete inputs?  I ask this because in your first screen shot (STAP_IO_view_onlocA_mod7.png) the X's for slot DMIO Remote Base 1, Slots 3 and 4 appear to have their X's out of order - this can only happen if you are re-mapping the I/O manually. There's nothing wrong with this, just making sure that you are wanting to do that on the X status bits, but you did not manually configure the I/O mapping for the analog output WY's themselves (they are IN order).

Just asking/noticing to help us understand better what is going on.

Well, now we had a new fault on the IO modules. Thankfully I wasn't dispatched until early Saturday morning 

The DMIO in question has 2 pcs BX-08DA-3 and 3 pcs BX-08DA-2B. PLC firmware 2.11.2 / DMIO firmware 4.2.239

This time the PLC/DMIO reported no module found in slot 6 - there are only 5 modules installed. Clicking on slot 6 shows "BX-08DA-2B detected in slot 6 but no module detected" (see screenshot). After some rework the PLC told me there is no module found in slot 7 (!) - still only 5 modules installed.

I removed the DMIO and attached the 5 IO modules to a DM1E and it detects 8 modules (!) out of which the first two are unknown (see screenshot). Some more shuffling around and replacing the first two modules (BX-08DA-3) resolved the issue, it now detects the correct number and module types and the system is up and running again.

It seems like the BX-08DA-3 is somewhat sensitive/vulnerable. I am planning to replace these with BX-08DA-2B and hesitate to use BX-08DA-3 in upcoming projects.

Does this documentation give any clues as to what might be happening to the BX-08DA-3 modules? Or why the PLC/DMIO are detecting modules that aren't real?

I received the PLC.  Thanks!

Is NetEdit enabled/disabled stored as a single bit?  Could this have been a bit flip?  I'm the only one who touched that program, and it was a new project as of December last year.

I used the hardware DIP switches to wipe out the Network settings and tried to recover the COMs that way.  Since it was the NetEdit setting, would using the DIP switches to completely wipe the PLC back to factory defaults and reloading the program have worked?  Asking in case I have to talk someone through this in the future.


Thanks,

I would be very surprised if the flash was corrupted. Everything else seemed fine. The only thing I saw was that NetEdit and legacy support was disabled on the internal port. As I mentioned we do automatically prompt when you open an older project...one where the security settings haven't been set previously. We've had a couple of reports of folks ending up with some stuff disabled. To this point we're thinking they are handling the dialog without fully overstanding what we're asking...but...it's certainly possible that something is busted in the process of migrating the old project.

Yes, using the magic handshake to wipe the memory will restore the comms. The bad setting is still in your project though, so as soon as you write your project NetEdit goes away again. You just need to edit the project offline or before you write it to the PLC. Go to the SysConfig->CPU Configuration and select "Security Settings..." in the middle of the dialog. If memory serves, your project had "Disable Unencrypted Programming" unchecked and both "Disable NetEdit Setup" and "Disable Legacy Protocols" were checked.

Since we prompt the user to choose security settings for old projects, we've had a few users inadvertently disable something they needed. As far as we are aware, the settings aren't changing themselves...although I've learned to never say never. If it happens again please let us know.

Do-more CPUs and Do-more Designer Software / Re: Incomplete Status Display

« Last post by franji1 on March 04, 2026, 05:00:21 PM »

Update:  Just noticed something new.  If I click No Status I get no status.   If I click All Status, the button doesn't stay illuminated, the single Status button lights up.   Is this normal?   I never noticed before, I was just looking at the actual status display in the windows where I wanted it rather than the button display modes.

Status button is an MDI specific status sticky button - click on a Data View, the Status sticky button turns/reflects status for that specific Data View on and off; click on a Ladder View, that Status sticky button reflects/turns status for that view on and off.
All Status ON is a normal button (not sticky) to turn status ON on ALL views (that support status)
Status OFF is also a normal button (not sticky) to turn status OFF on ALL views
Has worked this way since 1994.

I also compared programs between DMD and the PLC and got a match.

C103 is OFF - so there is no CYAN???
Are you also expecting to see ELEMENT status (in addition to the contact power flow status?).  This is an option in the Ladder View.

On the Display, Status tab of the Ladder Options, look at the Status group
"Show Element Status in Bit Contacts and Coils" may be UNchecked, but you want it CHECKED?

Let me know if this is what you are seeing

I don't think so.  Everything is synched with PLC and Saved to disk (no colored bars to the left)

I also tried switching to No Status and then back to All Status, with no change to which elements were live.

Realize as soon as you modify a rung, whether its a contact, a wire, anything in that rung, status is OFF for THAT ENTIRE rung.  Is this what you are seeing (you mentioned wiring)

Also, some boxes, when they are in a modified rung, show themselves in a partial status state (especially boxes that are not just a simple parm status, but a smart status layout - think PID).  They will arrange themselves as wanting to show status in this "smart status" layout, but do not actually display any status (because the rung itself is not necessarily running in the PLC since it's been edited).

I'm working on a program where in All Status mode, not all of the status is showing (though everything appears to work).  Screenshot below is representative, but there are a bunch of other rungs showing only partial status.   As far as I've seen, the missing status is all in the contact area, and the output box area all seem to work so far.

Also, that weird thing is back where Ctrl-Down doesn't work, but Ctrl-Up and other stuff does.

DMD v2.11.2, all firmware up to date, and PLC OS and booter are updated.
