The table below shows the mode of operation and the impact on I/O port No. 0
Mode of operation Description I/O port #0
Active low In case of alarm or warning, which arises
in case any of the alarm thresholds has
been reached or due to an internal error
the I/O port becomes low.
Output, active low
Active high
(Default = factory
setting)
In case of alarm or warning, which arises
in case any of the alarm thresholds has
been reached or due to an internal error
the I/O port becomes high.
Output, active high
Nominal master
(irreversible)
In case of alarm or warning, which arises
in case any of the alarm thresholds has
been reached or due to an internal error
the I/O port becomes high. In case the
alarm condition disappears, the
transmitter will remain in the alarm state
until it is reset manually. This mode is
implemented to prevent a frequent
switching into active/stand-by mode of
two redundant transmitters.
Output, active high
This port should be connected
to the corresponding I/O port
#0 of the redundant transmitter
which is set into redundant
slave mode.
Nominal master
(fallback)
In case of alarm or warning, which arises
in case any of the alarm thresholds has
been reached or due to an internal error
the I/O port becomes high.
In case the alarm condition disappears,
the transmitter will go back into normal
operation, which will set the connected
redundant slave mode into stand-by
operation.
Output, active high
This port should be connected
to the corresponding I/O port
#0 of the redundant transmitter
which is set into redundant
slave mode.
Redundant slave In case that the input port is low, the
transmitter will go into stand-by operation.
In case that the I/O port #0 (input) will
become high, the transmitter will go into
normal (nominal) mode.
Input, active high
This port should be connected
to the corresponding I/O port
#0 of the redundant transmitter
which is set into redundant
master mode.
Note:
Note: The redundancy mask determines which alarms or warnings trigger the I/O port #0 in
output mode. This is described in the chapter 6.5.11.
