I'm not sure, if I understand your description correct. I see  2 differnet use cases: A: Pass the JSON file content, without changing anything Open file, Read content STRING/WSTRING, Close file Send WSTRING via Web_Client_SL library B: Pass the JSON file content, with changing it Open file, Read content STRING/WSTRING, Close file Parse string into JSON object Edit JSON object Create WSTRING from JSON object Send WSTRING via Web_Client_SL library Remarks: When you do not have to change the content of the JSON object, you do not need the JSON library of CoDeSys. Just use the library CXA_FileAsync. It's a wrapper around the CoDeSys function, which are really hard to use. If the file format is STRING, you have to read it as STRING and convert it afterwards to WSTRING If the file format is WSTRING, you have to read it as WSTRING In my tests around 1 year ago, the CoDeSys JSON library was not very stable. I would use it only for very basic stuff but not for complex JSON's. ... View more

You can use the CoDeSys library: SysTask, which provides functions to create, change and get info of tasks. PROGRAM PLC_PRG VAR hTask: SysTask.RTS_IEC_HANDLE; // task handle udiInterval: UDINT; // intervall in micro seconds END_VAR // **** Implementation *** // get handle of current task SysTaskGetCurrent(ADR(hTask)); // get task interval SysTaskGetInterval(hTask, udiInterval);   ...
