M10 MultiController
nvi_xDO_AlrmStop is 1, then the DO object is locked regardless of the value
of nvi_xDO_AlrmStop.
Locking Release Level
Object locking release level. The value of this parameter defines the limit
level for value field of nvi_xDO_AlrmStop variable, lower values releasing the
object from standstill. To enable locking with value field, the state field of
nvi_xDO_AlrmStop variable needs to be zero (0).
0...200
Invert
This parameter inverts the state of the output network variable and the
physical state of the object.
Yes
No
NOTE! Object locking with nvi_xDO_AlrmStop variable functions also when
the object is inverted. The state of the nvi_xDO_AlrmStop variable still needs
to be zero for the object locking to work.
Trigger Level
(Value.State)
The value field of nvi_xDO_Switch1/2 variable can be used to control the
physical digital output by configuring this parameter with a desired trigger
value, higher values changing the physical digital output into ON-state and
lower into OFF-state. If the state field of this parameter is set to zero, then the
object will be ON when the state of an nvi_xDO_Switch1/2 variable is 0 and
OFF when the state is 1, and vice versa.
Value 0…255
State 0…1
E.g. 200.01 =
Value: 200,
State: 1
Example: If the Trigger Level (value.state) parameter is set to 11.00, the DO
will be in ON state whenever the value of an nvi_xDO_Switch1/2 is greater
than 5.5, or the state of an nvi_xDO_Switch1/2 is 0. The object will be in OFF
state when the value is less or equal to 5.5 and the state is 1.
(AlarmStop ON)
nvo_xDO_Switch
value.active
The influence of the object’s locking functionality on the output network
variable. The value of this parameter is the value shown in nvo_xDO_Switch
(state is 0) variable when the object is locked and this parameter is active (1).
Value 0…200
Active 0…1
When this parameter is not active (0), the value of nvo_xDO_Switch follows
that of the nvi_xDO_Switch1/2 variable (with a state of 0 if the object is
locked).
Example: If this parameter is set to 32.01 and the object is locked, then
nvo_xDO_Switch will be 16.0 0.
4.4
PWM-Control (Normal)
This function is mostly used in PWM-based heating and cooling control such as floor heating systems
and cooling systems. The output capacity of the system is adjusted by altering the time the object is in
ON-state during a configured duty cycle time.
For example, a 40% output capacity is achieved with a 100 second duty cycle by keeping the object
40 seconds in ON-state and 60 seconds in OFF-state.
