Update your settings

Hi. when i started adding MQTT to my system i first did it in LAD to make sure it worked, which it did. So now i wanted to convert it to SCL but now im getting:"Error assigning local data in ob 31 - processing will continue (no ob processing)" when i try and run my code. Ive attached images of my working LAD, and how the datablock works, when converted it into SCL this is my test code:
its placed inside of a Cyclicinterrupt with a 10000 cycle time
IF #Initial_Call THEN
"Data_block_1".control.Enable := TRUE; // Start the MQTT client
"Data_block_1".control.Subscribe := TRUE; // Subscribe to the topic
END_IF;
