Hi guys, i am new to all this MQtt business, and i wanted to do some test. So i have Ignition installed on my laptop, and Mqtt fx also installes. I have 2 transmitters - see below
I want to be able to subscribe to the data from Mqtt fx. I have seen thise topic collector , and when scanning, it finds this as a topic
So, when i subscribe i can see the values from Sample Tags.
I was trying to subscribe to the other tags, from My Group MQTT , but i can’t get the topic right.
First, i want to understand how did Mqtt Fx found this topic:
spBv1.0/Group/DDATA/Ignition/SampleTags
I presume it is somewhere defined in the engine, but not sure how to find it.
So, is it following this format?
namespace/group_id/message_type/edge_node_id/[device_id]
And if that is the case, i have tried this for subscribing to the other group:
Namespace = spBv1.0
group_id = My MQTT Group
message_type=DDATA
edge_node_id=Edge Node b5937c
[device_id]=PLC 1
I have based it off the engine folder structure, but it does not see to work
So can someone give me a hint on how these topics are created?
Thanks!
