For small project, I would like to use my industrial computer as a PLC + Industrial Computer. Like that I can save the cost of one PLC. That why I am using Codesys on Linux. With the nic it is not working. I already set the IP adress with /etc/network/interfaces. Can it comes from there ? looking to "Control Linux SL" docuemntation it should work with rtu.

RS485 doesn't seem very logical to use in VPLC's in my opinion. I also don't know if this is supported.... But for TCP/IP, I think you still need to configure the Nic settings. See the attached png. In my case enp6s0. When changing this setting, restart the VPLC. What is really nice, is that you don't have to configure the IP address setting in Linux. By setting the Nic to a certain IP address in the CODESYS instance configuration, this is automatically done for you. I only tested this with EtherCAT, but I guess this works the same for Modbus TCP/IP.

Hello, Today I am able to test ma industrial computer in my test bench. I am able to do all the configuration throught my VPN, 100% remote. I can see the gateway & the Virtual PLC. Now I would like to do some Modbus TCP Client & Modbus RS485. But I am lost due to docker ! When I go to modbus TCP it only gave me the docker network, but not my eth0 & eth01 When I go to modbus rtu, how can I create the link between Com number & my /dev/ttyRS485 Loic,

It seems you have 2 network interfaces. Did you try eth1? Did you already configure the IP address for this interface in Linux? If yes, then maybe undo this. - or only set eth0 in the Nic configuration without anything else (so no IP address, because this is already set in Linux). For more information about the Nic settings, see (probably already read it?): https://content.helpme-codesys.com/en/CODESYS%20Control/_rtsl_obj_deploy_control_sl_configuration.html PS, if you only want to run CODESYS Control SL, you don't necessarily need the Virtual PLC variant. You could also install and run the CODESYS Control SL Runtime in the Host operating system. This way you should also be able to access the serial port and directly access all ethernet ports. Maybe this is easier?

I made a mistake it is not end0 but eth0. But I have the same error.

Post by struccc on HTML5 Controls - string(>80) values
CODESYS Forge

(Post)
Dear all, does anyone have experience with HTML5 controls recently? CODESYS 3.5.20.30 / Visualization 4.6.0.0 I'd like to create a simple lightweight text editor, with proper multiline handling, cut & paste, scrolling, etc. And it seems to work fine, just have problems with strings longer than 80 bytes.... Declaring a variable sText1 : STRING(8000) and referencing it in the HTML5 Controls corresponding value property works perfectly one way: the code receive the data as a string (See log1)... (Note TypeID 1000...) Also sending back the data (seems to work (See log2) except it doesn't change the value of the bound variable. Probably the issue is with using SendSimpleValue method... Naturally, I could do a workaround, but maybe there is a more standard way to implement this... Please let me know if you have any suggestions.

Post by niallel on CamBuilder and first boundary position not zero
CODESYS Forge
talk
(Post)
Hi, I've read the CamBuilder documentation and it shows to use the left boundary of the first segment as SMCB.BoundImplicit(), so that the transition is as smooth as possible. With this it sets X and Y to 0. My first slave position is not 0 (say for example it's 100), so I would set it with SMCB.Bound(0,100). My question is that when the cam goes back to the start (Periodic := TRUE) , will it blend with the last position (360, 100) if I do this? I imagine it will, but the documentation isn't clear as the information in the Periodic Cams only says to set Smooth Transition in the cam properties - but when I'm defining it with code there isn't an option for Smooth Transition to be set. Hope this makes sense? Many thanks,

I do not have error anymore using nic with eth0 value. But my network it still 172.17.0.3 like the first picture.

Most likely your IP address is set to 172.... because you use a VPN connection to your device. Probably best to use the other Ethernet interface for your modbus communication.

Moin zusammen, ich habe vor die OPC UA-Verbindung dynamisch einzubinden und es auch nach der Codesys-Anleitung probiert. Dabei hatte ich aber das Problem, dass ich zusätzlich zu den Config-Variablen auch noch eine statische URL angeben muss, was dann aber den Sinn der dynamischen Vergabe verfehlt. Hat dazu schon jemand Erfahrungen gesammelt und kann mir vielleicht Tipps geben, was ich noch beachten muss? LG Denis
