Post by alez on CANOpen SDO to write VISIBLE STRING ^{CODESYS Forge talk (Post)}
Hello, I am experiencing difficulties in configuring a CANopen device by sending SDOs. In particular I am attempting to write an Object Dictionary that has VISIBLE STRING as the Data Type. When I try to configure the sending of an SDO from Codesys to configure this parameter I am not allowed to enter a string value. In my particular case I am trying to change the Manufacturer Device Name ( Index 0x1008 ). Could it be that Codesys doesn't manage these types of variables?

The green icon with an ! next to the device is concerning. Is the data type correct for the input, you are using a byte input but the description says string. Is there anything useful in the status tab?

Thanks, that's what I thought initially. The point is that I can't select a String type variable. See the attached image

Post by thn-power on How to change OPC NodeId IdentifierType ^{CODESYS Forge talk (Post)}
Hi Yet another OPC UA question. When setting up a OPC server using "Communcation manager" (Symbol set and information model) in Codesys the NodeId is always given as "opaque" type. At least when browsing using UAExpert. Other standard OPC objects use numeric (or string) identifier, but for some reason my variables seems to get opaque/binary type. See attached photo. How can I change this? I can't see that this is a parameter in the CodesysControl.cfg. Can this be specified in the information model nodeset? And is it possible to specify the exact numeric or string NodeId for each instance? And on a related topic, is there a way to export the OPC server nodeId's with variable name so that it can be imported in a OPC Client? The .xml files in the project folder does not seem to contain the NodeId.

Hello, anyone know how to get valiable value using a symbolic string name? For example: - send string to runtime using TCP/IP contains "GVL.TestINT" and get back the value. I need function that will translate the string to symbolic variable. Thank you. Andrea

The new (UTF8) string library is faster and can handle large strings. https://content.helpme-codesys.com/en/CODESYS%20String%20Libraries/_strlib_start_page.html PS, in CODESYS, the maximum string length is not 255 characters. The String functions of the standard library are limited to strings of 255 characters. But you can use other (memory) functions to handle strings larger than 255 characters.

The string_Util_Intern is not the library I referred to. With a CONCAT function (also with the string util library) a search is done for the NULL character. If you concatenate 20000 characters to one string, then the longer the string, the longer it takes to find this NULL character.
