Same for me. I have problems with UAExpert too. Can't see the Current Value of Enum and can't control. Did some Tests with Python opcua library. Not working with the communication manager so far.

Hello, I encountered this same error. I was able to resolve it by allocating more messages when I open the network driver (ctMessages:= 100). By default it is set to 25.

Hello If you uncheck 'Auto restart Communication', it will try once and never again. You can manually reset the slave if needed : Slave.xReset (or something similar) Or I have a ModbusRTU library if you want to try it.

I am using a new project, with nothing, but when add a simple cam table, and compile, there will be errors. It seems some add-on or library was missing, but there is not any hint. Could you help, please.

I am using TargetVisu in my v3.5 sp20 p6 (64-bit) project. I see no control that will allow me to bind, edit, and display a LREAL variable. Am I missing a library? If it exists, why can't I see it?

Hello, you probably fixed in this meanwile, but I think your problem comes from dependencies of other libraries. I see in the Project column of errors the "caa types extern" and "caa fb factory", that both have dependencies. Try to check there. Regards, Francesco

Hi! Does anyone have an example of ReadNCFile2 with Sentence Modifier? Current examples on CODESYS help page are outdated and have a lot of errors, like "SMC_CNC_LibParams.MAX_SUBPROGRAM_NESTING_DEPTH" calls, which are not present in current version of SMC3_CNC library.

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.
