Subscriber Box

The properties that generally relate to the reception of an EAP telegram are defined on the configuration page of a Subscriber (see next illustration). These properties include:

Receiving Options
With the help of the Receiving Options selection you can configure whether all incoming EAP telegrams – i.e. irrespective of the sender – should be received or whether only EAP telegrams from a certain sender should be received. In the latter case the AMS NetID of the desired sender should be entered in the input field behind Publisher NetId.

Multicast Configuration
With the help of the Multicast Configuration option you can specify whether the Multicast address entered should be reported to the configured network interface card. The Multicast address parameterized here must be identical to the Multicast address configured for the sender if the latter's EAP telegrams are to be received (see Multicast in chapter Publisher Box).

Standard Multicast MAC The Beckhoff standard Multicast address 01:01:05:04:00:00 is always reported to the network interface card for a TwinCAT EAP device, even if the Multicast option is not selected.
