Page is the Exchange number.
Length is the number of bytes of data in the Exchange. This is calculated from the Exchange offset for the point and the point size.
Period is the time in milliseconds (ms) at which the Exchange must be polled. This is based on the poll rate for the fastest point in the Exchange.
Producer is the name of the Series 90 device that supplies the Exchange data.

Flags contains the flags for the Exchange. Currently supported values are:
Important: If the provider is using multicast addresses then the multicast address needs to be pre-pended to the address "126.96.36.199:2:1". This means that an EGD provider is multicasting to address 188.8.131.52 on exchange 2 and the data begins at offset 1.
