Hi everyone, Iβm new to CODESYS and Wago devices, and Iβm trying to set up Modbus RTU communication. I have a Wago PFC200 (8110) and a 750-653 RS485 module, and I want to read data from an energy meter using Modbus RTU. Thanks in advance for your help!

make sure the PLC and the programming PC have IP addresses that are on the same subnet, you'll have to know the default address of the PLC or you may need to connect to it with a special cable and use a software tool to set the IP address.

Hi, I am currently creating a documentation for our library with DocScripting. In the process, I noticed that Visu images are created before the merge and transform, i.e. "screenshots" of the different Visus. Unfortunately, these are not used in the later process (Merge/Transform). Is there a way to set it up so that they are found in the html file?

I have {attribute 'checksumnoinit_override' := '2629838988'} {attribute 'init_related_code' := '5c6efcf8-e0f4-4166-a9fa-17eadd8908df'} VAR_GLOBAL RETAIN PERSISTENT {attribute 'order_in_persistent_editor' := '0'} segmentValue: ARRAY[0..49] OF REAL; {attribute 'order_in_persistent_editor' := '1'} segmentTime: ARRAY[0..49] OF REAL; // Generated instance path of persistent variable PRG.test: INT; // Generated instance path of persistent variable PRG.nw_storage: SysSocket_Implementation.SysSocket_Interfaces.SOCK_ADAPTER_INFORMATION2; END_VAR When I have changed PRG.nw_storage it will not be stored at a power off, but if I do a: sudo systemctl restart codesycontrol and then a power off it will be stored. Is there a way to store persistent variables without a restart of codesyscontrol? Can anyone explain how and when CODESYS store persistent variables?

I use ethernet ip scanner and the connection type is set to multicast. After running the PLC, the ethernet IP will have a connection timeout every 10 seconds. What is the reason for this error?

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.

One thing you could do is create an object with the variable as field with a function and procedure to get the variable (read) and set the variable (write). These are then called from your program and the vizualization.

Resolved this. There is a config file called CodesysControl_User that I had to edit to set the driver to component 5. I deleted the semi colon next to Component.5=CmpEt1000Drv

Another way to resolve this is to set Codesys to use a specific version of the offending library under Placeholders in the Library Manager.

Hi there, I am having a similar problem like you. I have 3 screens connected to one PLC. I have set 3 different URLs for them. But 3 of them are still dependent to each other. How can I make them independently ? Kind regards, Jin.

Solved: update all the software to the latest version, set optional user management, have a symbol configuration, check tasks priorities.

Hello Julian, could you please check in Chrome Password Manager Settings if the option "Offer to save passwords" is set? With this option selected, a pop-up message will then show up asking whether or not to save the password. Choose OK. Hope this helps.

To search for an exact phrase, put it in quotes. Example: "getting started docs"
To exclude a word or phrase, put a dash in front of it. Example: docs -help
To search on specific fields, use these field names instead of a general text search. You can group with AND or OR.
