C
CoDeSys provided by Festo: CoDeSys stands for Controller Development System and is a
development environment for PLC/IPCs. CoDeSys provided by Festo allows the configuration,
commissioning and programming of different Festo components and devices.
D
DHCP: Dynamic protocol for automatic assignment of IP addresses (Dynamic Host Configuration
Protocol).
E
Ethernet: Physical protocol and network for connecting various devices.
G
Gateway: The IP address of a gateway is necessary if stations from other networks (other net ID) are
to be able to connect with the device. If a gateway is entered, it will be assumed that a connection
to other networks is possible.
I
IP address: An IP address is used to address a network as well as an individual station 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
"netmask".
M
MAC address (MAC-ID): Fixed assigned address clearly marked for Ethernet device (Media Access
Control).
N
Netmask: The netmask for IP addresses defines the bytes used for addressing the stations (host ID)
by means of "0" as a placeholder. A 1 as placeholder defines the bytes which the contain the
network address (Net-ID).
R
Router: Device for establishing networks. The router is responsible for passing on data, which is not
intended for one's own segment, to another segment or to the next router.
S
Switch: Various network ranges can be separated by means of a so-called switch. A switch analyses
the data packages and passes them on only to the slaves addressed. This increases the data
throughput of the network. Formerly hubs simply passed on the data packages, but nowadays
switches are used. An Ethernet network therefore has a real-time facility.
T
Target Support Package (TSP): All of the configuration and expansion files that are required to make
a specific controller (target system) usable for the CoDeSys provided by Festo programming
environment are combined in a Target Support Package.
TCP/IP: Combination of the protocols TCP and IP, the most widely used protocol for communication
via Ethernet.
