Post by alex-wall on Network Variables not updating ^{CODESYS Forge talk (Post)}
This worked for me. I had four identical PLC's. Three of them worked just fine with 255.255.255.255 as the broadcasting address but the 4th would not update the variables. Changed it to 192.168.x.255 and everything worked.

Go to Online>Communication Parameters...>Gateway>TCP/IP> Click on "New..." and reestablish your connections with whatever IP address and set up information you have. Bypass whatever is necessary as you may have to redownload to the PLC.

I am having the same trouble. However, if I change the Login Configuration settings to 'Type: Login using the credentials determined at runtime' then the Connection information continues as 'Connection state: Connecting' and 'Error information: OK'. There is no User Management on the source PLC.

Scan from "IP-Configuration" with PC connected to first EtherCAT slave and "EtherCAT" tick box ticked gives slave info. As does ticking the "Emergency" tickbox.

Post by gatto on Backtick identifiers ^{CODESYS Forge talk (Post)}
Hello, I’m in Codesys 3.5.20.40 and I try to declare the variable ´var1´ but I get an error. here : https://content.helpme-codesys.com/en/CODESYS%20Development%20System/_cds_rules.html i read : Backtick identifiers By using backticks, characters can also be used in identifiers that are not normally permitted in identifiers, such as special characters. The acute accent character is used for backticks: ´ (Unicode: U+02CA) The use of backticks is recommended in order to be able to use the same identifiers in CODESYS as in other programming languages or documents, such as circuit diagrams. Any character may be used between two backticks, except line breaks and other backticks. Keywords are also allowed as identifiers between backticks. Examples: ´Variable+9´ ´INT´ The backticks are part of each identifier and therefore var1 and ´var1´ are two different identifiers. Example PROGRAM PLC_PRG VAR var1 : INT; ´var1´: INT; END_VAR var1 := var1 + 1; ´var1´ := 12; Are there any limitations or is something missing in my development environment?

To simplify your problem you shall not select dongle and get dongle errors. Do as shown In some cases you need 2 different licenses depending on the metrics. And yes the system gives not always give proper error messages when you try to reinstall a license

Hi gilad, I cannot tell for sure. But I think it should work on any PLC that is capable of doing motion control. Best regards, Georg
