I got a solution: tell axios to return a blob instead of a json use FileReader object to convert blob to DataURL jConfig = { headers: { authorization: 'Bearer ' + _sIdmToken }, responseType: 'blob', } jResp = await axios.get(`${sMgr}/packages/${AppsID}/icon`, jConfig) blob2DataURL(jResp.data, setImg, img) function blob2DataURL(blob, callback, img) { let fr = new FileReader() fr.onload = function (e) { callback(e.target.result, img) } fr.readAsDataURL(blob) } function setImg(dataURL, img) { img.src=dataURL }

There is also another possibility, which is especially interesting when it is necessary to convert a lot of numbers into texts. e.g. If the PLC sends status messages as numbers, which should be displayed as text in the active language. PLC sets interger variable iStatus Range of iStatus 0-100 Define localisation variables "Status000" - "Status100" Status000: "Stopped" Status001: "Prepering" Status002: "Running" : Status100: "Done" Define and use function localize (see article Integer-in-hex-notation ) /** * returns the translation for the localization variable whose name is created dynamically * @param {string} sPrefix * @param {int} iValue * @returns translation text defined by inputs * @example // java script console.log(cxt.localize("state", 1)) // returns value of localization var: state001 // usage in iq-text where items[0] is an integer <%= localize("state", items[0].value) %> */ localize(sPrefix, iValue) { return shmi.localize("${" + sPrefix + ("" + iValue).padStart(3, "0") + "}") }

When you connecting with UA Expert I expect, that you use the same security settings. Therefore I expect the problem on Opc UA client side (check docu of the client). I once had problems with establishing a connection with WebIQ UA client, and couldn't find a missconfiguration. At the end I delete the configuration and created it new, and than it worked. I don't think that the problem is on OpcUA server side, but as I mentioned you can try version 1.18 and check the OpcUA diagnostic on datalayer.

We got this working on our PLC by doing a reset and then reloading everything. Uninstalling and re-installing just the app did not work so something else in the data must cause the error.
