Hi Yu-wen Tang! Thanks for sharing this FB for MQTT. It's amazing!! I am trying to increase the size of the array for subscribe topics to 20 (i need about 50 topics but i am testing it with 20) but i am unable to do this. I have edited the loops at suscribe, unsubscribe, suscribedArrivedMsg REGIONS from 9 to 19 to fit the size of the new array. I also have modified the Data types to support 20 items but i am unable to get it work. I got an 16#80C4 error (TSEND_C error) when i tried to suscribe. I am using your S7-1200 FB in a S7-1214DC/DC/DC. Thanks in advance. :) PD. the 10 item version works fine.

Dearf luisromeral, I attach here an example project expanding the subscribe/unsubscribe/suscribedArrivedMsg topics to 50. Due to time limit, I have only done a simple testing connected to a local mosquitto broker without problem. Please test it in detail yourself and modify it if necessary. I should admit that this FB can be optimized but it is not now; therefore when you increase the topics, you should also pay attention to the usage of work memory (attached project almost 60%).
