Post by imdatatas on String length issue in GetRecipeNames method ^{CODESYS Forge} ^talk ^(Post)
Hi, If the string length in the GetRecipeNames method is lower than the default value, there will be a problem with the resulting Recipe file names. For example; When the method in the link is called, let's say the defined string length is 19. In this case, the string content is corrupted as in the image. strArr: ARRAY[0..9] OF STRING(19); https://content.helpme-codesys.com/de/libs/Recipe%20Management/Current/pou-RecipeManCommands/GetRecipeNames.html The same problem does not occur when the string definition is made in the default size. strArr: ARRAY[0..9] OF STRING; FYI Regards, Imdat

Post by bertcom on Converting each character to a string into ASCII ^{CODESYS Forge} ^talk ^(Post)
Good afternoon, I have a project where i need to split a string and send it in ascii code to an Domino Printer. Concept: i get an String from an Zebra scanner looking like this : " R002043;5410761402862;Oil Plus 2C Comp.A - Gris Belge;1286193824;" To start is the ";" the seperator. i found some functions to delete the ";" in a string. this is okay but now i want to convert each digit in the string into ascii like this: R=82 0=48 0=48 2=50 0=48 ... This because the printer wants to receive a string like this: <esc>OQ001TE 82 48 48 50 48 ...<eot></eot></esc> Anyone who can help me with setting me on the right track with some advice?

Post by eaglealex on Length of string and Array of bytes ^{CODESYS Forge} ^talk ^(Post)
Hello! I have tried read a file to the string variable. But I faced a problem - there is about 2800 bytes of information in file, but string have a limit 2393 bytes. I made two variables with same address (for automatic convertion) - string[3000] and array of bytes[1..3000]. And I noticed that array of bytes contains all information from file, but string shows only first 2393 bytes. So I have lost information. Is there really such a limitation? Or I have an error in my program and Codesys 2.3 have no limit for such kind of conversation between string and array of bytes? Thank you very much!

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);

Post by mmpl on Array to String ^{CODESYS Forge} ^talk ^(Post)
I would like to create one large JSON string from an array of objects, where each object contains a value. My current approach involves using a for loop and string concatenation, but with 20,000 elements in the array, this method takes almost 7 seconds and negatively affects the PLC scan time. Is there a more efficient way to accomplish this?

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

Thank you for your answer! I know that 0 will be the end of the string. I checked it. There is no 0 in array of bytes. I made screenshots. There is array of bytes, aborted string and the result of my test via online converter.

Post by rmaas on STRING conversions to DWORD ^{CODESYS Forge} ^talk ^(Post)
Hi, The '' characters in Codesys are there only to indicate it is a STRING type. They are not actually added to the string, maybe you are adding them unintentionally in the concat function? You can send your data from Codesys to Hercules to verify... Another option is to send the data as an array of bytes instead of a string, with every byte representing 1 ASCII character. https://www.ascii-code.com/ This way you are 100% sure Codesys is not adding any unwanted characters.

Post by tvm on Timer On Vijeo ^{CODESYS Forge} ^talk ^(Post)
Vijeo doesn't support TIME variables, so the easiest thing to do is convert to a STRING in your program, and use that variable. You could use TimeAsString:= TIME_TO_STRING(TimeVar) to get a string that looks like this: T#5h10m45s200ms

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.

So it's currently mapped to an array of BYTES? Can you create a UNION? TYPE sBytesString : UNION AsBytes: ARRAY[0..127] OF BYTE; AsString: STRING(128); END_UNION END_TYPE Map it to the bytes, read it in the STRING!

Good afternoon. I want to communicate with a Domino Industrial Printer using its Codenet protocol. The printer wants a series of Hexadecimal characters with no spaces or '00' characters. Because of that i chose the option to make the prefix and subfix for my code in a string. I have variable data in another string. With a complete program of a lot of CONCAT functions i eventually get the format of code that the printer accepts ( tested it with the hercules tool). Hercules String : 1B4F513030311B7532626C61636B04 The problem is : Codesys adds automatically 'code' to the code to show it is a string. Codesys string : '1B4F513030311B7532626C61636B04' The printer does not understand this. My idea is to convert the string datatype to an LWORD. I have no idea how to do this. I random types in STRING_TO_DWORD, as return i get 0. That didn't worked. Also on internet the explenations around string converting in codesys are very limited. If there in anyone who can explain me how to do it, i would appreciate it a lot ! Thank you!

I don't fully understand the issue, but if the encoding is a problem you can try testing with WSTRING datatype instead of STRING. https://content.helpme-codesys.com/en/CODESYS%20Development%20System/_cds_datatype_wstring.html

Post by peterned on Array to String ^{CODESYS Forge} ^talk ^(Post)
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

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?

Post by amy123 on JSON Utilities ENUM to STRING ^{CODESYS Forge} ^talk ^(Post)
Hello, Is it possible to get the string returned from the ENUM JSONType? I read that with regular enumerations you can add '{attribute 'to_string'}' and access it. However, this is from the compiled library, so I can not add that attribute. When I try to use TO_STRING(JSONType) it returns the integer as a string. Ex. jsonType :=TO_STRING(pJSONData^._aJSONData[i].eType); gives '8' instead of NONE Thanks!
