Example of a selective polling exchange :
WaveCard is configured like described below,
POLLING_ROUTE GROUP_NUMBER
Equipment A address 0x01
Equipment B address
Equipment C address
Equipment D address
Equipment E address
After transmitting the REQ_SEND_POLLING request, the distant equipments react in the following way:
•
Equipment A : responds to the request. PARTICULAR CASE, this module is the
first of table POLLING_ROUTE, and the first polling frame is sent in point-to-point mode;
•
Equipment B : responds to the request (belongs to the interrogated group)
•
Equipment C : responds to the request (belongs to the interrogated group)
•
Equipment D : responds to the request (belongs to the interrogated group)
•
Equipment E : no response (doesn't belong to the interrogated group).
