EasyIP: The EasyIP protocol enables the simple exchange of data between controllers. EasyIP is a
UDP-based point-to-point Ethernet protocol that uses port 995. EasyIP controllers can usually
operate as both a client and server. Even controllers that cannot function as a server such as
diagnostic devices or visualisation computers can operate with EasyIP. In theory, any number of
controllers can be connected to an EasyIP network because it does not contain any logical
connections. Only the performance of the hardware determines the number of packages that can
be sent simultaneously or processed by the server.
I
IP address: An IP address is used to address a network as well as an individual slave in the network.
For this the IP address contains the net ID (specifies the address of a network) and the host ID
(specifies the address of an individual station in this network). The numbers in an IP address
which represent the net ID and the host ID are defined by the specification of a so-called "net
mask".
T
TCP/IP: Combination of the protocols TCP and IP, the most-widely used protocol for communication
via Ethernet.
U
UDP: A minimal, connection-free network protocol that has a lower protocol overhead than TCP. This
has the advantage of a faster exchange of data. Due to the lack of a reply, the correct
transmission must be ensured, for example by means of a user program.
