Power supply failure on
station with NET-ID 1 If the power supply of the station with NET-ID 1 fails during
operation or a factory reset is carried out on this station, the
other NET stations can no longer be notified of the
associated operating mode change. This also applies if the
standard and safety circuit diagram stop due to a class A
fault (see Behaviour of easySafety after a fault,
a
page 624).
NET stations with NET-ID 2 - 8 on which REMOTE RUN is
activated therefore stay in RUN mode until the missing sign
of life is detected. The time until the missing sign of life is
detected depends on the baud rate and is from 180 - 9000
ms (
a
section “Diagnostics” , page 544). Up to this time,
a NET station 2 - 8 operates with the data previously
received via the NET.
The further behaviour of the NET stations 2 - 8 depends on
whether REMOTE IO is also activated as well as REMOTE
RUN:
• NET station 2 - 8 with activated REMOTE RUN
This type of NET station sets the data received via the NET to
zero. It retains its operating state and sets the diagnostics bit
ID1 to 1 (see following safety measure).
• NET stations 2 - 8 with activated REMOTE RUN and
REMOTE IO that function as input/output devices, i.e.
without their own circuit diagram (does not apply for
easySafety)
This type of NET station sets the data received via the NET to
zero. It switches to the STOP mode if the device display is
showing the Status menu. The device follows NET station 1
when it switches to RUN mode.
Safety measure: On every NET station with a program,
monitor the diagnostics bits ID.. in order to detect a missing
NET station as quickly as possible (
a section
“Diagnostics” , page 544).
h The easySafety device can only be operated on the NET as
a station with a circuit diagram.
