Post by expertplas on No connection to opc server from codesys opc client ^{CODESYS Forge talk (Post)}
Hello, we have aproblen to connect our CODESYS OPC Client to the OPC Server. We installed the client according the CODESYS manual. We can browse the server and variables can be linked to the PLC. I created a self signed certificate for the CmpOPCUAClent as described. The server has a cerificate also. I copied the certificates to the trusted zone of server and client. But when it comes to data exchange we get an error message. "Communication error in data source OPC UA Library. Error ID : 7001 German : "Kommunikatinsfehler inder Datenquelle OPC UA -Bibiothek. Es wurde kein genauer Fehler angegeben. Fehler ID : 7001" It semms that there is no cerificate exchange. We are working with CODESYS 3.5 SP19 Patch 5. Can anyone here say something about this error or has an idea for a solution? Thanks.

It appears you have some incorrect syntax. Are you able to post a snip of the code where the error occurs?

I have found the solution, the CmpEventMgr version has to correspond with the 3sLicense version.

Post by totorovic on CSVReaderInit returns error : INVALID_HANDLE ^{CODESYS Forge talk (Post)}
We changed the path where the CSV file is. From intern memory of the IPC to a USB key. We still have this error 'INVALID_HANDLE'. We must restart the Codesys runtime to clear it. That is a big problem for us because machine is in production. @eschwellinger What do you mean by "this is a security issue not to read/write in the plc allowed path"

Hey, I am facing the same problem. Basically UA Expert and other programs work fine with the login credentials. But codesys can not use them properly. I can see the server login to it manually but when I download the program and run the datasource never runs... Currently I am facing the same Error ID: 7012 and cant get it running properly.

Post by dhumphries on Rounding error in simple addition ^{CODESYS Forge talk (Post)}
I have discovered a rounding error, either in Codesys or in my understanding of numbers. The attached ladder shows that when the up button is pressed the number increases by 0.1, when the down button is pressed number decreases by 0.1, after several button presses the number isn't equally divisible by 0.1. Have I discovered a bug or am I doing something wrong?
