How to differ producer and cunsumer in cJSM componenet

[Anonymous]

When I was step through this article, how do Talend differ wich component is the producer and wich is the consumer?
In the picture below, the producer and the consumer are the same componenet: cJMS. Just the name is different.


And also, in the configuration part there is no difference. This is interesting me, 'cause if I need to create a producer or a consumer how can I be sure, am I create this or that? 

+ Info:
I'm using Talend Open Studio for ESB 7.1.1.
