LON
General
LON nodes can be flexibly networked by one or several transmission media,
such as for instance a twisted pair of conductors ("Twisted Pair"), the 230V
power supply or radio and freely communicate among each other. Modifica-
tions and maintenance work such as extensions using high capacity tools and
components by now available on the market, are possible at any time and
while the system is in operation.
As such, LON offers a consistent and particularly economical and fast solution
for simple and more complex automation tasks.
4.1 General Safty Information!
Warning!
Prerequisite for the observance of the intended use of the hardware and/or
software is compliance with the generally accepted technical rules and stan-
dards. The user must observe the safety and accident prevention regulations
applicable for the individual application. Here special emphasis must be placed
on measures intended to protect from indirect electrical shock.
Beyond the regulations generally applicable, further rules might become rele-
vant pursuant to the actual application, such as safety or elevator systems.
Where automation solutions are realised with the hardware and/or software
which in the event of a malfunction could cause injury or major material dam-
age, the user has to take suitable external and independent measures to ensure a
safe operation of the system even in fault situations.
Such measures could, for instance include the use of forcibly opened safety
limit switches which lead to a controlled or uncontrolled disconnection of the
energy supply to machine drives.
