Do-more CPUs and Do-more Designer Software / Re: Bug in FTPPUT

« Last post by MikeS on May 21, 2026, 11:42:02 AM »

i should have mentioned that the DMLogger does use network broadcasts to get data from the CPU to the Logger dialog, so yes, it does have to run on a local PC that can accept broadcast packets.

Do-more CPUs and Do-more Designer Software / Re: Bug in FTPPUT

I did try that yesterday before power cycling the BRX. I turned on ST35, set messaging to level 2, and left the Logger set to receive packets from Any but it received no packets at all when retrying the FTPPUT command. That network was on a remote system that I have limited access to so I think the Logger was being blocked from network access. I was remotely connected to a local PC at the site but I think the Do-More Logger running on that PC was blocked by Windows and I only had a User login, not Administrator.

I will have to wait a few months before being able to test again with the local BRX which I know does work with the logger.

DMLogger can be used to display some of the FTP traffic between the BRX CPU and the FTP Server. This is a high-level look at the CPU's interaction with the FTP Server - it's not as detailed as a wireshark trace - but it might tell us why the connection attempt is failing.

Run Debug -> Do-more Logger. Make sure to select the option to 'turn on ST36' and select 'Level2 - Update ERR and MSG' for the messaging level.

Once DMLogger is up, use the 'Change' button to set the 'Accepting Packets from' address to the BRX CPU you want to monitor.

Any time the FTPPUT instruction is executed you will see the interaction traffic displayed in the logger.

one caveat is this logging mechanism is generic, meaning that any instruction in the CPU that has logging capability will do so when the logger is activated, so depending on what else is happening in the program you'll see traffic unrelated to the FTPPUT in the logger.

Do-more CPUs and Do-more Designer Software / Re: Limit for number of simultaneous connections on port 28784?

« Last post by BobO on May 20, 2026, 09:25:45 PM »

Not on that port specifically, but the programming protocol is limited to 32 concurrent sessions. I'm not familiar with the Do-more IO server though, so I'm not sure what it is running.

Is there a limit to the number of simultaneous connections on port 28784?

I have PLCs that I'd like to have monitored by multiple Wonderware/AVEVA InTouch PCs running DOMORE OI Server.

Thanks!

Do-more CPUs and Do-more Designer Software / Bug in FTPPUT

« Last post by Scot on May 20, 2026, 11:58:41 AM »

This is going to be difficult to duplicate because it takes a long time, but I've had this same problem with multiple BRX units.

I'm using SD cards in a BRX to store log data that it pulls once per minute from several other Do-More PLCs. There's a lot of data so it's separated into 10 different CSV files.

Once per day at midnight it uses FTPPUT commands to upload each file one at a time to local FTP server.

Every few months, the FTPPUT commands just stop working and returning an error condition. The BRX can still successfully PING the FTP server but cannot execute an FTPPUT. If I power cycle the BRX, everything is working again. It requires the power cycle too. Changing to Program Mode and back to Run Mode doesn't fix the problem.

Maybe the FTPPUT command is not releasing file handles with the network device and eventually can't get a new handle? Not being the author, I don't know. But it seems to be a consistent time period before needing to be power cycled.

I have this system installed in 3 plants. The other 2 plants are newer and only have 2 files they upload each night. Those take much longer before needing to be power cycled. These are connected to the FTP server through the onboard ethernet port, not the POM ethernet addon.

Do-more CPUs and Do-more Designer Software / Re: Bug in PID View?

« Last post by franji1 on May 19, 2026, 09:02:54 AM »

Definitely a Designer bug.  The mapping of the drop-down in the PID form view back to a specific PID was not correct.

So sometimes, when you pick a different PID loop in that drop down, it thinks it's the same one that's already there.  The drop down shows what you selected, but the view believes it's still on the original.  Or even worse, a THIRD PID loop will be shown in the view.

The name in the TITLE BAR tab is the ACTUAL one being utilized by the view.  The one selected in the drop-down is not (unless it happens to match the one in the title bar).

Thanks again, nice to know that you identified a bug 

Your proposed workarounds are not really solid either. Both options you mention are opening the PID View with diverging loop names, see attachment. But at least now I know there will be a bugfix in an upcoming release.

Out of curiosity, is this a bug in DMD or in the PLC? I.e. is the PID View being populated with data from the project file on disk or data directly from the PLC? Can I fix this by deleting the PID structures and create new ones?

It's a bug.  It's been there a LONG time.  It was an easy fix.

Until we come out with a new version with the fix, the best workaround is to NOT use the Combo Box drop down in the Form section of the PID view.  When you want to open up a new/different PID View:

• use the PID Overview view (View->PID Overview) and double click on the one you want
• use the PID View Online Toolbar and that will prompt you (via a different dropdown combo box) for the PID loop you want

So sorry for this.  Thank you for finding it - I can't believe this hasn't shown up sooner

I just sent the project to support.

Got it.  Definitely seeing strangeness.  Will need to look a little deeper.

Are you using the latest firmware for BRX (2.11.3)? Also, recommend updating to latest Designer software (2.11.2).  I don't think that will address this issue, but those are better than previous 2.11.x versions.
