Communication and connection

There are various additional modules
available to connect the controller to the
IT infrastructure.
19.1

Profibus DP module

PROFIBUS DP (Decentralised Periphery)
for control of sensors and actuators by a
central control in production engineering.
Here in particular the many standard diag‐
nostic options also come to the fore. Fur‐
ther deployment areas are the connection
'distributed intelligence' , i.e. the net‐
of
working of a number of controls to each
other (similar to PROFIBUS FMS). Data
rates of up to 12 Mbit/s over twisted pair
and/or fibre optic cables are possible.
19.2

Module for Modbus RTU

Modbus RTU (RTU:
[Remote Terminal Unit] ) transmits the
data in binary format. This ensures a good
data throughput, however the data can not
be directly evaluated by humans, rather it
must first be converted to a readable
format.
19.3

LAN module

'Local Area Network' , shortened to
A
'LAN' , is a computer network. The phys‐
'LAN' is limited without
ical extent of a
additional measures to 500 m and is gen‐
erally used for home networks or small
companies.
Communication and connection
19.4

WLAN module

Wireless Local Area Network (WLAN)
refers to a local radio network and nor‐
mally refers to a standard of the
IEEE-802.11 family. In some countries
(e.g. USA, Great Britain, Canada, Nether‐
lands, Spain, France, Italy) the term Wi-Fi
is widely applied to this narrower concept.
