Ads error 1804 twincat

У нас распространены операционные системы с интерфейсом на русском языке, потому что мы живем в России. И все бы ничего, когда б не… русский язык.

Первая проблема после установки твинката на ПК — это файервол. Его настраивают кардинально и целиком, т. е. просто отключают. Контроллер после этого сканируется и появляется в сети, но попытка добавить роутинг обламывается сообщением:

Add route to remote system failed.
ADS Error 1796 (0x704): ‘ADS ERROR: reading/writing no permitted’

Объяснение простое — у пользователя на стороне контроллера не хватает прав для добавления записи в роутер контроллера. На самом же деле… впрочем, пойдем по простому пути.

На ПК, который скоро станет контроллером, открываем Панель управления → Администрирование → Управление компьютером → Локальные пользователи и группы.

В подразделе Пользователи находим Администратор и переименовываем его в Administrator. В подразделе Группы находим Администраторы и переименовываем их в Administrators.

Наслаждайтесь.

TwinCat3 Beckhoff «Add route to remote system failed ADS Error 1804 (0x70C)»

für Deutsch siehe unten

————————————————————————

Hi everyone, I will post in English as my German writing skills are not so good but below you can find my post Google translated for your convenience. Replies in both German and English are very welcome!

I have a problem connecting with a Beckhoff CX5120. Two months ago together with the help of an expert PLC programmer (I am a complete beginner) I set up the Beckhoff PLC to run a simple program. I managed to connect my laptop running TwinCat 3 to make modifications to the script and upload it to the PLC. However now, two months later, I am again trying to make some modifications to the program and although nothing has happened or changed in the past months it is not working anymore. When I first started with the PLC I remember I had some connection problems but I managed to solve them in the end and everything was working as it should.

However now when I try to connect to the PLC while the PLC computer is in Config mode it works, but as soon as I switch to Run mode the connection stops working. When I first start TwinCat with the PLC connected it shows the name (CX-2X61C0) of the PLC computer and everything seems in order. When I then Build the solution also there are no error messages. However if I then either press Activate Configuration or Restart TwinCat in Run Mode it does not give me any error messages but also it does not work and I cannot login. If I then select again the CX-2X61C0 from the dropdown menu it shows «CX-2X61C0 (ERROR)». Finally if I try to do Restore Connection it gives me the following error message: Add route to remote system failed ADS Error 1804 (0x70C). Furthermore the green/blue gear icon which is in the bottom corner turns red. At this moment I also cannot connect to the PLC computer anymore and I have to manually go on to the PLC computer (by connecting a screen and keyboard to the CX5120) and switch there from Run mode to Config mode. As soon as I switch back I can again see the PLC in TwinCat without an error.

I have been trying everything from creating a new project file to restarting multiple times but I cannot get it to work which is very frustrating because everything worked fine 2 months ago! If anyone has some ideas for solutions I would be very happy to hear them, thanks in advance!

GERMAN:

Hallo allerseits, ich werde auf Englisch posten, da meine deutschen Schreibfertigkeiten nicht so gut sind, aber unten findest du meinen Beitrag Google übersetzt für deine Bequemlichkeit. Antworten in Deutsch und Englisch sind sehr willkommen!

Ich habe ein Problem mit der Verbindung mit einem Beckhoff CX5120. Vor zwei Monaten habe ich zusammen mit einem erfahrenen SPS-Programmierer (ich bin ein absoluter Neuling) die Beckhoff-SPS eingerichtet, um ein einfaches Programm zu starten. Ich habe es geschafft, meinen Laptop mit TwinCat 3 zu verbinden, um Änderungen am Skript vorzunehmen und es auf die SPS hochzuladen. Aber jetzt, zwei Monate später, versuche ich wieder einige Änderungen am Programm vorzunehmen und obwohl in den letzten Monaten nichts passiert oder geändert wurde, funktioniert es nicht mehr. Als ich anfing mit der SPS zu arbeiten, erinnerte ich mich, dass ich einige Verbindungsprobleme hatte, aber ich schaffte es, sie am Ende zu lösen und alles funktionierte wie es sollte.

Aber jetzt, wenn ich versuche, eine Verbindung zur SPS herzustellen, während der SPS-Computer im Konfigurationsmodus ist, funktioniert es, aber sobald ich in den Ausführungsmodus umschalte, funktioniert die Verbindung nicht mehr. Wenn ich TwinCat zum ersten Mal mit der angeschlossenen SPS starte, wird der Name (CX-2X61C0) des SPS-Computers angezeigt und alles scheint in Ordnung zu sein. Wenn ich dann die Lösung baue gibt es auch keine Fehlermeldungen. Wenn ich dann im Run-Modus entweder auf Konfiguration aktivieren oder TwinCat neu starten klicke, bekomme ich keine Fehlermeldungen, aber es funktioniert auch nicht und ich kann mich nicht anmelden. Wenn ich dann erneut den CX-2X61C0 aus dem Dropdown-Menü auswähle, erscheint «CX-2X61C0 (ERROR)». Schließlich, wenn ich versuche, Verbindung wiederherzustellen, gibt es mir die folgende Fehlermeldung: Hinzufügen Route zu Remote-System fehlgeschlagen ADS Fehler 1804 (0x70C). Außerdem wird das grün / blaue Zahnradsymbol in der unteren Ecke rot. In diesem Moment kann ich auch keine Verbindung mehr zum SPS-Computer herstellen und muss manuell zum SPS-Computer wechseln (indem ich einen Bildschirm und eine Tastatur an den CX5120 anschließe) und dort vom Betriebsmodus in den Konfigurationsmodus wechseln. Sobald ich zurückwechsle, kann ich die SPS in TwinCat wieder fehlerfrei sehen.

Ich habe alles ausprobiert, von der Erstellung einer neuen Projektdatei bis hin zum Neustart, aber ich kann es nicht zur Arbeit bringen, was sehr frustrierend ist, weil vor zwei Monaten alles gut geklappt hat! Wenn jemand einige Ideen für Lösungen hat, würde ich mich sehr freuen, sie zu hören, danke im Voraus!

Twincat ads error 1796

I ran in to some trouble.
I created 2 virtual machines to try out ADS communicating One machine is a PLC (TC2 32bit (runtime)), other is (should be) a client (TC2 64bit engineering+ Visual studio adsAPI) that should read/write from/to PLC VM.

1. problem : TC2 64 bit engineering does not find a PLC VM. (i know it is possible to find it (https://www.reddit.com/r/PLC/comment. ogram_running/ )but mine does not find it)

2 problem: (bigger one). I can find this VM PLC from other 32bit VM with TC2 32bit, but when I try to «add route» I get ADS error 1796.

I saw one post on this forum about very similar issue(http://www.plctalk.net/qanda/showthr. ADS+ERROR+1796), but could not find answer here.

Maybe someone here tried this out and could help me out?

thanks you all in advance

For those who are instrested I managed to fix my problems.

2 Problem [Solved]: silly mistake Beckhoff add route requires PC name and password so entering it removes the problem and route is added

1 Problem [Solved]: dont know why but TC2 64 bit (engineering) does not install good on Win 7 (pro), trying this on W10 mashine worked like a charm

hope this helps someone

did you install as ‘run as admin’?

I run TC2 64-bit on windows 7 (home), no problem.

Hello!
Have you tried to recreate (delete/add) the TwinCAT/AMS-routes? Delete them in both ends, and then create it on the PC/Developer machine-side.

I’m assuming that the TwinCAT status icon goes red on the PLC-side?
Also, to figure out why TwinCAT does this you can always look into the EventViewer. Right-click on TwinCAT status icon «Tools -> Event Viewer».

FYI, you don’t physically need to connect to the PLC if you want to debug it. All Beckhoff PLCs (at least running win7/win10, which your CX5120 does) have remote desktop enabled by default.

Hello,
I am seeing «ads error 1796 (0x704)» during the routing of EK1100 with Twincat3.1.

Username: Administrator and password:1 has been entered but showing the above error code.

__________________
Expectations lead to disappointment. Appreciation leads to satisfaction.

Yes,I did,I have no problem with the local system, since I have the remote system which is in WinCE in config mode all the time.

every time I login to the remote system I receive a message says : «No program on the controller, Download the new program?»
I think maybe the program should be downloaded to the remote system «WinCE», but I don’t know if there is such a way to do that.

The WinCE system doesn’t have that problem before and it was on running mode with its own application running, But after I create my project and I send the new boot project. this status occurs and the twincat starts in config mode.

I appreciate your cooperation.

The message you receive states that no program has been downloaded into the controller.

1. Ensure that you’ve selected the right type of PLC in your PLC configuration (resources tab in PLCControl).

2. Clean and rebuild your PLC program.

3. Save your PLC program.

4. Rescan you PLC project from System Manager.

5. Download again the configuration.

6. Select the right runtime system (PLCControl -> Online -> Choose runtime system).

8. Create the boot project.

You should also check:

1. Ensure you don’t have any page fault as per a bad memory assignment if you are using pointers.

2. Ensure you are not accessing bad memory addresses (out of bounds arrays. )

Good luck with all those, come back with the result.

What I would do:

1. make a complete backup of your CFCard.
2. Delete the Documents and Settings folder.
3. Delete the TwinCAT boot folder contents.
4. put back the cfcard into the CX controller and restart it. Wait for it to create the folders again.
5. reconfigure your IP addresses in your CX.
6. start system manager, create again the route between your computer and the controller.
7. in config mode, and once you are connected SCAN the IO Devices and then SCAN for boxes. ==> this will create the correct IO cards and devices for you.
8. add your plc project, scan it and assign the right PLC variables to the right IOs.
9. try to generate assignments, download the current configuration.
10. in PLCControl log in and create the boot project.
11. in your System manager go to SYSTEM CONFIGURATION ==> BOOT SETTINGS (Target) ==> Select RUN MODE (ENABLE).

Try it again and come back with the results.
