CODESYS Virtual Control for LINUX

espenbo · November 5, 2024, 12:44pm

Hello

I downloade the codesys virtual controll for linux.
I have tride with a user with sudo rigths and root user.

I have tride to follow the online help

I have communication with the PLC and have installed the docker image
Docker_codesyscontrol_virtuallinux_4.12.0.0_amd64.tar.gz

The docker image is running

I have set the port 11740 to be forwarded.
see help page: Establishing a Connection to an Instance

But when I try to connect I can’t connect to codesys on the wago edge computer.

I ssh inn to the computer and look if there could be a fireware.

What can I try next? any tips on something I can try?

Have you deployed it from CODESYS, using the Deploy Control SL ?
You should install and deploy from there (no CLI docker commands are necessary)

By default the container is using host network, so you don’t need to forward any port.

Is it up and running ?

When you have solved your issue consider installing the vendorcheck, in order to use WAGO libraries on the Edge :

I’m trying to go through the entire installation of Codesys on the edge machine again. I’ve written everything step by step. However, I’m not able to establish a connection. Do you have any other tips I could try?

connecting to the plc

Install and Deploy image from codesys

add a new instance

Set to Autostart

start the instance

Runtimelog

Trying to connect.
Can’t find any device when searching

Trying with the IP adress of the wago edge computer

ssh to the edge computer is working

Hi Espen.

I tested and it works. Logged in as root when installing.

Package:

Instance (remember port setting):

The first time you log in a codesys runtime user has to be configured:

(Enter details in the next window after clicking YES.)

Hi @espenbo

Looks like you’re Using VPN?
Maybe the 11740 Port is not forwarded in your VPN Firewall?

I tried the Beta, and also the Releases 4.12 and 4.13 of the Virtual Control and the connection was never a Problem.

Did you tried it with a direct Connection to the Device via LAN?

You can also start the Container with network “host” like @quenorha did.
every NIC you add in the Parameter list will be linked directly into the Container and is not visible in the Host then.
At the first Start with the Virtual Control i locked myself out of the Edge Computer

CODESYSUser · November 18, 2024, 5:33am

Hi,
I would recommend to add a virtual EdgeGateway Instance.
Start this and add a new Gateway in CODESYS …scan the virtual PLC by this new added Gateway.
For licensing it is mandatory to use 4.13.0.0 Version and add the license Server in the Host. (Use the CODESYS Installer to add the License Server Update command to your CODESYS Version)
