ILS Workbench configuration
Configuration in the ILS Workbench of the cooperation partners ILS Technology LLC. Here,
ILS Workbench configuration means only the configuration data loaded on the CP and
required by the → ERPC application.
Industrial Ethernet
LAN system complying with IEEE 802.3 (ISO 8802-2)
IP
Internet Protocol
A network protocol widely used in computer networks. It represents the network layer of the
OSI model for TCP/IP-based networks. The IP protocol alone is connectionless and not
permitted. The most important information is the unique IP address.
The blocks of data are sent to the destination computer independently. IP does not negotiate
anything with the destination computer. There is no end-to-end error check.
Frames can arrive in a different order from the order they were sent in. TCP is responsible
for putting them together in the correct order.
IP access control list
Access control list for IP access protection in Ethernet
Connections are only possible to communications partners whose IP address is listed in the
IP-ACL.
IP access protection
Access protection based on IP addresses. This makes it possible to restrict access to the
device (for example a communications processor) via defined IP address ranges or single IP
addresses.
IP address
An IP address consists of a numeric code made up of four numbers from 0 to 255 (for
example 192.168.0.55). It is the numeric address of a particular computer in the network /
Internet.
ISO-on-TCP
Communication connection of the transport layer (layer 4 communication complying with
ISO) mapped to TCP.
Messages can be exchanged bi-directionally on an ISO-on-TCP connection. TCP provides
data stream sequence communication without segmenting data in messages. ISO on the
other hand is message-oriented. With ISO-on-TCP, this mechanism is mapped on TCP. This
is described in RFC1006 (Request For Comment).
