ARP

Description 1

Library implements the Address Resolution Protocol.

The following Interfaces have to be implemented: 1. IEthernet: Interface to the Ethernet Adapter. SendARP() shall send the given Ethernet II Frame (CmpSysEthernet.sendethframe()). 2. IARPCallback: The Interface Method RequestCallback() is called as soon as the Request has received the response to its ARP request (requested MAC and IP).

Program Sequence: 1. Call Request.Send() one time (each call generates an ARP Request on the network). 2. Call IEthernetClient.Receive() (= Request.Receive()) until RequestCallback() gets called by the Request FB. If more than one response is expected on a single request, IEthernetClient.Receive() can be called continuously.
