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?

max. string length in Codesys is 255 chars. It's not possible to cram 20,000 things in a string. If you need to send the data to another device, send the whole data[] array (as byte array, without doing anything to it) and extract the information on the other end. As each struct member has a fixed size (81 bytes, as per you declaration), this will be easy. To save some resources, consider declaring string lengths - e.g. if the max possible length for key is 10 chars, declare it key: STRING(10); and it will occupy 11 bytes instead of 81

Nice puzzle for a Saturday afternoon :-). Here my suggestion: VAR sInput : STRING := 'R123'; byChar : BYTE; sOutput : STRING; i: INT; END_VAR sOutput := ''; IF LEN(sInput) = 0 THEN RETURN; END_IF FOR i := 0 TO LEN(sInput) - 1 DO byChar := sInput[i]; sOutput := Concat(sOutput, TO_STRING(byChar)); END_FOR

If a size is not specified, CODESYS allocates 80 characters by default for a string. After 7 seconds, does your Json_string contain all of your 20000 key/values? Or is the result truncated to 80 characters?

Hi Thank you for you reply. Yes I can concatenat longer string. I am using string_Util_Intern libraray for concat. The issue is abot plc performance. It takes 7 second. I am looking to improve time.

you try to convert a WORD with BYTE_TO_HEX directly? Using https://de.helpme-codesys.com/ lead to the SM3_shared lib. There is a function: https://content.helpme-codesys.com/en/libs/SM3_Shared/Current/SM3_Shared/StringFormat/Word_To_HexString.html

Post by rjonker on codesys mqtt publish serialization ^{CODESYS Forge} ^talk ^(Post)
pbPayload is a pointer, which it expects to point at a STRING. If you point it at an address holding a different data type, it will just assume those bytes are part of a string and likely trundle along memory until it finds a null byte (0x00) that would normally signify the end of a string PublishMessage := BOOL_TO_STRING(boolVariable);

@TimvH, Thank you, i think this way i can seperate the complete string to characters. Next part of the topic is converting the characters to an ASCII code. Is there an standerd function in Codesys for this? I alredy searched a few hours for it on the internet. no succes.

Post by timvh on Help with DynamicTextGetTextW ^{CODESYS Forge} ^talk ^(Post)
First of all you need to enable "Use unicodestrings" in the Visualization Manager. This function returns a pointer to a WSTRING (not STRING). To get this wstring value, do something like this: VAR myWstringVariable : WSTRING(255); END_VAR myWstringVariable := myResult^; // this is dereferencing the pointer to the WSTRING.

Post by vstrom on Recipe definition, how to have the Name string in current language? ^{CODESYS Forge} ^talk ^(Post)
I'd like to know if it is possible to have the "Name" field, in the recipe definition, language dependent. Something like to have the possibility to put there a string ID that will be add to the GlobalTextList. In this way it can be translated and when showed in a Visualization screen its value depend on the current language. Thanks.

Hello TCIS_Send needs to be longer than 4 bytes because idata is 28 bytes long. There may be other ways, but I would make a UNION with string/array of bytes. Write your STRING into the AsString part then copy the AsBytes part into TCIS_Send (Elements [3] to [30]) then 252 would be in [31] (I've assumed the idata is always the same length)
