Can you post the new code that you have by chance? Also, are you able to send the values of tags dynamically with the RTAC in this JSON format? I'm running into a lot of road blocks with it.

Just adding: sSubscriberdata := ''; Right before your memcopy should fix the extra characters. It is because your are copying 36 characters into a string which can contain more than 36 characters and there is garbage left in the extra characters. Regarding the parsing of json, I usually build a structure that mirrors the json data and use the available methods in the IIoT library to parse the data and fill the structure.

It turns out that you can build JSON structures without ever calling the JSONBuilder function block directly. Instead, create a pointer to JSON.JSONData and invoke the necessary methods on its dereference. The parent object has a parent index of -1 (and an index of 0). EVERY other item (including keys, values, empty arrays and sub-objects) created by the setX methods needs the index to increase by 1. Then use the JSONByteArrayWriter FB to generate your JSON string

To search for an exact phrase, put it in quotes. Example: "getting started docs"
To exclude a word or phrase, put a dash in front of it. Example: docs -help
To search on specific fields, use these field names instead of a general text search. You can group with AND
or OR
.
