power supply system. The supply voltage must be
between 12 and 30 V
S Error messages should only be acknowledged once
the cause of the error is removed and no further
danger exists.
S Automation equipment and devices must be designed
in such a way that adequate protection or locking
against unintentional actuation is provided (e.g. ac­
cess checks, password protection, etc.).
S For those devices operating in networks, safety pre­
cautions must be taken both in terms of hardware and
software, so that a line break or other interruptions to
signal transmission do not cause undefined states or
loss of data in the automation device.
