1 The Festo_EasyIP.lib library
1.1 What is EasyIP?
EasyIP is a proprietary Ethernet protocol from Festo. EasyIP allows the simple connection of different
Festo controllers to form a network. 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 devices that cannot function
as a server such as diagnostic devices or visualisation computers can operate with EasyIP. In theory, any
number of devices 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.
EasyIP is implemented as an IEC library. The following table shows which operands are defined in EasyIP
and which can be exchanged via EasyIP in combination with a CoDeSys-based controller.
