I found my problem. The parentIndex from a new object was not connected to the root parent index

Dear reader, I am using the codesys JSON utilities SL, 1.9.0.0 library. And then specifically the FB JSONBuilder. I need to create a main object with at least 2 objects in it. The first object is no problem, but I cannot insert the second object into the main object. See attached my code and the result I get. I am assuming that I am doing something wrong with the parent index but have tried a lot and can't get it done. Kind regards, Rob

Hi, I have an array: aTelemetry: ARRAY[0..65536] OF BYTE; I put data inside this array. the amount of elements filled inside this array can be variable all the time. I want to publish this array via mqtt but if i publish the whole array i get alot of blanc data/white spaces as data. So i only want to send SIZEOF(aTelemetry) without empty elements. suppose I fill the array with 60000 bytes, then I don't want to include the last 5536 Bytes. So the question; is there a function/manner to see how much...

Hello, I have to send alot of data at once. Using a WSTRING higher than 16100 results in codesys not displaying it anymore. Is this assumption correct or is the data just not being send anymore? See picture for clarification

Sorry for the late respone, i was out of office. I have installed the library maneger with the specific liberary in the root of my application see image in attachment. When i browse to the parameter in the library (online and offline) i'm not able to edit the parameter. neither through the library manager or thourgh the plc program (see my initial post). Am I missing something?

Hello, In my application, we want to adjust the maximum packet size we can send to the mqtt broker to 128KB. I found that the current packet size is 4096. See image. I have tried to adjust this parameter, see highlighted part in the other image, but I constantly get an [AccessViolation] from the "CheckPoint" function. see image acces violation. Does somebody has an solution on how to adjust this packetsize? Kind Regards

Try removing the last topic. I succesfully established connection to the AWS broker with no (or another) last will topic

@man2002 did you had any luck so far connecting to the AWS broker?

Hello, I have the right permissions. I uploaded the certificates just as in the tutorial (https://faq.codesys.com/pages/viewpage.action?pageId=119504904). The AWS client FB remains on a TCP_READ_ERROR. It seems that we cannot/should not connect to AWS. This could be due to the certificates. See attachment. Now, if we are to follow the approach in this Codesys documentation with the necessary adjustments following changes to the AWS console, we would be generating a certificate signing request (CSR)...

Hello, We are using the CodeSyS IIOT package. Specifically the AWS IoT Core Client library. Online there is a roadmap what you can follow to connect to AWS, see: https://faq.codesys.com/pages/viewpage.action?pageId=119504904 We followed this roadmap. We entered in the AWS IoT Client the ClientID, Endpoint, port and topics. We uploaded the (3) certificates that AWS broker creates into the core, see attachment. The AWS client FB remains on a TCP_READ_ERROR. It seems that we cannot/should not connect...

Hi, I am using Codesys IIOT library. In our Codesys program, we want to communicate with a mqtt Broker service. This broker lives in Amazon Web Service (AWS). There is a tutorial online from codesys online how to connect to an AWS broker. (LINK: https://faq.codesys.com/pages/viewpage.action?pageId=119504904) In this tutorial, codesys itself creates a certificate to be used by AWS. The problem is AWS wont work with a certificate issued by codesys. Now the question is whether codesys can work with...

I couldn't do step 37 till 42 because the PLC Shell is not working (see attachment). I got the certificate and private/public key send by the guy who made the AWS mqtt server. That certificate should correspond with the AWS Server.

Ill upload attachments again in this post. I followed that guide. At step 67 my program differs. mine wont connect to the broker.

Did you get you get you CodeSyS AWS client connected to the broker? I'm having trouble connecting to the broker. My Client only tells me it's busy, without any errors. I installed certificates inside codesys. any clue?

The AWS IOT Client has Busy = TRUE but it wont connect to the broker, see image. I got a certificate with private key installed in codesys(attachment) which corresponds with the AWS IOT server. What can be the problem im really out of idea's
