Ok das heißt dann für mich, daß ich mein Programm mit dem ENC fertig schreibe und später auf den 5500er wechsle. Mit dem Bug den 5200er zu verwenden wäre eher kontraproduktiv. Ich harre dann der Pings, die da kommen und bedanke mich bei allen Helfenden und helfen werdenden
To oversimplify it, think of the W5500 chip as a telephone exchange. When you contact (or try to contact) an address you 'dial' a number (IP address) via an arbitrary line (socket) and all replies from that address are martialled to that line (socket). This can be (in processor terms) some time later, so while you are waiting for a reply you can also try to contact another IP address, but you need to use a different line (socket) because the first one is busy waiting for a reply. That means that you can be talking to up to 8 devices at once. Once your first conversation is finished you can hang up (release the socket) and the line (socket) is then available to contact another address.
Sockets can be used for other purposes too (like DHCP for instance) but, as I said, the description is an oversimplification.
