returns
Err
,
Hi
or
Lo
value. This parameter has the following options:
•
no change
- means that at the time of an alarm state there is no change on the
output,
•
immed. OFF
- means that in times of an alarm state the device immediately
switches the output to low state,
•
immed. ON
- means that in times of an alarm state the device immediately
switches the output to high state,
•
timed OFF
- means that in times of an alarm state the device switches the
output to low state after a time delay set in the
Timing
parameter block,
•
timed ON
- means that in times of an alarm state the device switches the output
to low state after a time delay set in the
Timing
parameter block,
–
Levels
block parameter - these parameters allow the user to set the range of
changes of the output depending on the input signal, discussed below in this
Chapter
,
–
Timing
parameter block - these parameters allow the user to set the delay time
change the output state and minimum duration of the output state, discussed below
in this
Chapter
,
Levels
parameter block (see
Fig.
7.87
,
Fig.
7.88
and
Fig.
7.89
)
These parameters depend on the
Mode
parameter. The options are:
–
Level
- this parameter defines the source signal level at which the output switches
the state (from low to high state or from high to low state), occurs for the mode:
•
above level
- above the level we get a high state at the output,
•
below level
- below the level we get a high state at the output,
–
Lower level and Upper level
- these parameters define the range at which a switch
the output state (from low to high state or vice versa from high to low state), occurs
for the mode:
•
inside range
- if the input data is within the defined range at the output we get
a high state,
•
outside range
- if the input data is outside the defined range at the output we
get a high state,
–
Hysteresis
– this parameter defines the offset for a switch state on the output,
Timing
parameter block (see
Fig.
7.92
)
The parameters of this block include:
–
ON delay
– it is the time that must pass from the time of a switch request to
the actual switch from low state to high state (see
Fig.
7.90
),
–
OFF delay
- it is the time that must pass from the time of a switch request to
the actual switch from high state to low state (see
Fig.
7.90
),
–
Min.ON time
- the minimum duration of a high state (if the output switches to high
state the low state will occur not faster than
Minimum ON time
),see
Fig.
7.91
,
–
Min.OFF time
- the minimum duration of a low state (if the output switches to low
state the high state will occur not faster than
Minimum OFF time
),see
Fig.
7.91
,
Note!
If the external output is active (see the parameter
Output active=yes
in the
Chapter 7.15.3.2. Modbus MASTER - Device channels parameter block
) for
Mode=disabled
the device sends the '0' value to a Slave device.
