PlcSubscriptionEvent extends PlcReadResponse

[Andrey Skorikov]

Hello all,

the interface PlcSubscriptionEvent extends PlcReadResponse, but I am not 
sure whether that is correct: every response has a corresponding 
request, which is obtained by calling getRequest() on the response. 
However, what request shall be returned if getRequest() is called on 
PlcSubscriptionEvent? In my understanding such request does not exist, 
since the subscription request has the corresponsing subscription 
response and not subscription event.
