9. Plug again the wired connectors.
ð Now you can bring your system back into operation.
The installation guidelines contain information about the interference free deployment of a
PLC system. There is the description of the ways, interference may occur in your PLC,
how you can make sure the electromagnetic compatibility (EMC), and how you manage
the isolation.
Electromagnetic compatibility (EMC) means the ability of an electrical device, to function
error free in an electromagnetic environment without being interfered respectively without
interfering the environment.
The components of VIPA are developed for the deployment in industrial environments
and meets high demands on the EMC. Nevertheless you should project an EMC planning
before installing the components and take conceivable interference causes into account.
Electromagnetic interferences may interfere your control via different ways:
n Electromagnetic fields (RF coupling)
Magnetic fields with power frequency
n
Bus system
n
n Power supply
n Protected earth conductor
Depending on the spreading medium (lead bound or lead free) and the distance to the
interference cause, interferences to your control occur by means of different coupling
mechanisms.
There are:
n galvanic coupling
n capacitive coupling
n inductive coupling
n radiant coupling
