New VisiLogic wont compile Samba program with 26 displays says maxis 24 but previous version compilled without any problem.
This dispays number limit is artificial and decrease Samba functionality.
Please remove this limitation.

Hi;
Memory Values can be backed up
Do this Before working with the OS
From VisiLogic:
Connection -- lower section - Just above communication and US
Export PLC Operands to Text file
or Export PLC Operands to Binary file.
Then do the reverse -- Import the values back in
DanT
Thanks DanT
Is not help unfortunately for remote OS updates.
Because new OS eraising all MI and also network parameter's, then PLC system restart with all zero and you cannot connect it due PLC name , IP etc. all zeroes and no possible restore parameters just for reason unable to connection.
With previously OS updates was never eraising parameters, I'm using Unictonics PLC ~15Years and first time this issue popped up.
If you can physically make updates then is can set up back, but I have many abroad system's and canot update without on site helps what is very inconvenient due most consumers is end users and not PLC geek . Also is looking unprofessional.

Another issue pop up with new operating system!
When updating PLC with new OS it erasing all data (initialize - reset) , with previously updated OS was not erasing .
Why this happens?
How to avoid erasing data with OS updates?

You've defeated your own argument here. Your "CD hard disk" ONLY has the data in it because either the PC or you have written data to the disk. The situation is exactly the same with the PLC. If you need optimised data to be saved by the system, you need to record it in some way. And then have the PLC programmed to be able to retrieve it as necessary. Kratmel has shown you a way of doing it which is very simple and effective, but I do things a little differently.
Perhaps you have not considered the way many people would, perhaps accidentally, use NVM in a PLC. If it was written to every scan, MTBF would be markedly lower. Using RAM totally alleviates this issue, but it needs the battery. I have not personally used a plc without a battery, be it super-cap, rechargeable or standard. They may be out there, but I'm guessing it is not done much due to potential durability issues.
My systems are 24/7 and constantly create optimised amounts for various parts of the program. These amounts are written every minute to a data table, and every 24 hours that table is written to the SD card as a new file, not FIFO. I routinely go through those files remotely or when next on site, and if it is worth changing any power up value to one of the optimised amounts, I do. Regardless, I have the latest best values, at most 24 hours ago in PLC run time, stored for use in a component that doesn't need a battery. Ready to reload as necessary by a few simple button pushes. Hmmmm......that sounds like...clicking the mouse on my computer and opening a file I have saved to be used by a program already installed on the PC, and all of it coming from the "CD hard disk!"
Thank you Ausman for advice on.
is different situations can pop up when have hundreds of consumers happy story and bad story.
Some consumers use sytem > 7 year and not have problem but some in some countries have always been issues with electricity cut off, also PLC are very sensible to SD card brand , some time it lost SD card, loose capacity, lost formatting etc.
Best way will be some amount of NVM build in PLC what can be use way you described.

When you say "remote session", what are you referring to specifically?
I mean when cosumer connected PLC using phone APP or another remote access program.
PLC firmare is detect remote session and showing confusing message screen instead just block any try go to info mode.
If SB 140 will show remote session then can be write zero to SI 50 to block " confusing message screen" and restore value 4 when session finished.
SB 36 - also have strange behave can set 1 by program (info screen pop-up) but cannot be creared, only physically need press Esc-

Require a password to change the value of SI 50 or password protect a button for SB 36, or place the button on a screen not accessible remotely.
Is exist an SB 140 -Remote access - read only, but it not react to remote session.

Any critical value that the programmer knows will not need to be changed by the user should always be set in a power-up. That should be SOP.
Some values can be set only on site when equipment set up and its not predictable values.

This is silly. You want flash memory to store data in the PLC? Unitronics has supplied the facility for adding flash memory to the PLC. An SD card is just additional flash memory for you to use as needed or as you see fit. Nothing artificial about it.
I wish Unitronics use non-volatile flash memory build in to forgot about this problems.
Instead babysitting with backup battery's. and get silly questions from consumers.

To me, it is simpler to STORE constant values to registers in a "restore to factory" subroutine called whenever you need, rather than use DT with "part of project" which implies operations with database.
Some critical parameters I write in power up section and reprogram PLC...

Is the any SI, SB pop up while remote sessions are Active ?
-

Thank you for guidance kratmel .
Of course is an solution, just to fill this "Part of Project" table need
1. program PLC and make justification with equipments - get operating parameters and write its down.
2. Fill "Part of Project" table then program PLC again.
Correct?
-
System bit SB 8 not help because data already lost after week of PLC off.
Use dedicated SD card, an artificial solution, additional hardware just to fix failure of PLC . Is like add to you TV disel generators.
PC won't boot one morning because the bios battery is dead - But all data safe in CD hard disk!
Data Table with the "Part of Project" checked - Please explain where can do this check.

But need block PLC going to info mode remotely !
If set zero SI 50 it not possible go info mode physically.
Need someway link SI 50 with remotes.
-
Hello,
Thanks for security updates.
Another big problem still exist is PLC trying going to Info mode while remotely controlled if client push and hold screen.
Then client see INFO MODE not supprted and randomly push screen and cannot go out due PLC asking password but not showing it and not react to Esc button.
Please update software to block PLC going to info mode remotely absolutely.

On my client have backup battery empty and lost all settings MI's Vision V570
How to program settings in non-volatile memory to restore "factory setting" if lost data?
PS. is nonsense nowadays use volatile memory related battery condition :(
-
Thank you AlexUT ,
We are waiting, our clients in panic and bombing us.
Is any indicative time what takes this fixed ?

Hello All,
Is planned any update on Remote operator Android V13 , V14, it won't install get message what is for old versions of androids?
New VisiLogic wont compile Samba program
in Vision & Samba PLC + HMI Controllers & VisiLogic Software
Posted
Ok , I will use previous Visilogic version for this application.
