This looks to me like a single device and you choose which scale reading via MODBUS command. I see no reason to close the connection, once established, nor any reason to use two sockets.
I'm not familiar with these scales so I may be misinterpreting something. You can choose the timing between commands without closing the socket.
-
This makes no sense to me. If you were communicating as though it was one device, then why was it necessary to close the connection between MODBUS commands?

they share the same IP address
That's your problem - you can't have two devices on the same network with the same IP address.
-
It's telling you what the problem is: "Stop reason ; No Application"
This means exactly what it says, there is no application in the PLC. This can be caused by several things, but most likely due to removing power from the PLC with no battery or a dead battery. The solution is to replace the battery and reload the application from VisiLogic.
-
Why are you trying to communicate with two different devices through the same socket? Use two different sockets, one for each scale - then you don't have to waste time connecting and disconnecting.
-
I think you should use v.9.8.96 for database 155.

Is there a "database table" to Visilogic version cross reference available?
This pinned post is where we've been collecting that information.

Try Alt-PrtScrn.

Have you elevated this to Unitronics Support (support@unitronics.com)? Keep in mind that this is a user forum staffed by volunteer users who for the most part are not Unitronics employees. Most of the people here do not have the type of specialized knowledge you are seeking. In any case, I recommend patience as most forum members likely don't check this board every day.

Is there any progress regarding this or some sort of workaround?
@Cara Bereck Levy do you by any chance have an update for us?
-
You can request it from support@unitronics.com

Did you install the driver?

If instead you are asking if there is some way to download images without VisiLogic, the answer is no.

In most cases, if nothing else is changed except the addition of images for the List of Images by Pointer, it is possible to download the updated VisiLogic file to the PLC without stopping or rebooting the PLC.
However, be cautious. Things can go wrong anytime you download a program update to a PLC and if it is running a mission critical application, you might want to think through the ramifications carefully in the event the PLC must be stopped for some reason.

I wanna take the project file from the good one to the dead one or use my PC as a PLC
You cannot use your PC as a PLC. As for uploading the project file from the good PLC, that is likely not possible. The programmer must specifically allow that when downloading the project into the PLC. If they did not do that then you can't. No harm in trying though. Just connect VisiLogic to the PLC and select Upload instead of download. It will tell you the answer.

Making my PC as a replacement for the dead screen by the means of the remote access and project file from the good screen.
Is this possible?What do you mean "project file from the good screen"? If you have a good PLC with a project file, why are you trying to resurrect the PLC with the bad screen?

You can find the swapper version on the Unitronics website: https://www.unitronicsplc.com/software-visilogic-for-programmable-controllers/ Here's a direct link to the zip file: https://downloads.unitronicsplc.com/Sites/plc/Visilogic/Swapper Versions/Unitronics VisiLogic_9.3.1_Swapper.zip
I'm not 100% sure you can do a full install from this version, but You can certainly install any other version and Version Swapper and this swapper version and swap to it. (I know that seems confusing).
You can also email support@unitronics.com and they will send you a link to obtain the full install version.

Does the Remote Access application require an ethernet card installed in V350?
No, you can connect your PC to the PLC via serial connection.
-
I would think that if the PLC were to be powered down for an extended period of time the smart thing to do would be to replace the battery immediately upon power up. The batteries are cheap, readily available, and extremely easy to replace.
-
I could be wrong, but I got the impression OP was referring to UniLogic.
-
It doesn't pause anything. The Timer Out bit just doesn't pass power flow until the timer expires.
-
Just change the PLC model in the program temporarily to test, then change it back. I don't program UniStream very often, but it seems like I've done this successfully in the past.
