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 levih on FbHTTPs_Get how to get data from a website and use it in codesys ^{CODESYS Forge} ^talk ^(Post)
You get an array of DWORD into your receive buffer. You need to process this into usable data, before you can fit it into your DUT. I've made it work using FbWrite_ToIEC_ByRule in stead of Fb_JSON_ParseAndModify. I've attached images of the code. You receive the data into ARRAY[0..1023] OF DWORD. Then you use that array as the input for fbWrite_ToIEC_ByRule. To get the output from this you define a rule to fit the expected data structure including nesting levels. The you feed the rule into FbWrite_ToIEC_ByRule and then you can set the output to be of your DUT type.

I want to send a string to a tics TCP/IP server. I got i working with the Net Base lib. for communication good with this tcis i need to by array of byte I want to include a string in the third position of the array TCIS_Send[1] :=254; //this valus is fix for evry communication TCIS_Send[2] :=80; //this valus is fix for evry communication TCIS_Send[3] := ; here I put my and my string is lik this 5806509-DRAP10#AB#3452302073 TCIS_Send[4] :=252; //this valus is fix for evry communication

Hi, I need to figure out witch indexes of an Array containing the highest and lowest values. Typically search for the 5 lowest values and result the indexnumbers containing the 5 lovest values. is there a library for this, or codeexample?

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

IF you create an ENUM {attribute 'qualified_only'} {attribute 'strict'} TYPE E_IO : ( FIRST := 0, SECOND := 1 ); END_TYPE You should be able to access the array items like: IOCard_OUTPUT[E_IO.FIRST]

Post by rckalex on Changing Trace Variable at Runtime ^{CODESYS Forge} ^talk ^(Post)
Is it possible to change the variable being traced during runtime? I would like to use the CURRENTCLIENTID in combination with an array of real numbers to alter the traced variable in a display window, without needing to create separate visualizations for each variable.

Post by ton on Length of string and Array of bytes ^{CODESYS Forge} ^talk ^(Post)
When you use a string value 0 will be the end terminator. Everything after this will not be in the string. I guess byte 2394 has a value 0.

Does anyone know how to access the ModbusTCPSlave_Diag.ComState without declaring each one by the device name? I attached them to an array but since I may have dozens of devices this is still a bad solution.

Hi. Does anyone know how to fix a problem with losing focus of a variable in FBD editor. Sometimes when trying to edit variable name, array index, etc. in network, editor randomly exits "text edit mode" and variable is replaced by text you were typing.
