L-INX User Manual 180 LOYTEC
Version 4.0 LOYTEC electronics GmbH
Note: Due to the static input NV which is required for a CEA-709 alarm client point, adding
alarm clients will change the static interface of the device.
The new static input NVs representing the alarm clients on the local device need to be
bound to the alarm outputs of the remote device. A CEA-709 device normally delivers
alarms through an output NV of type SNVT_alarm_2 located in the node object of the
device, therefore the new input NV on the local device must be bound to the alarm output
NV of the remote devices node object. All required information is transmitted over the
alarm input NV, so it is possible to later bind the alarm client to any other alarm server
without rescanning the network.
Note: If connected via LNS, the binding to the nvoAlarm2 NV is made automatically by the
configuration software in the download process.
6.16 Math Objects
6.16.1 Create a Math Object
Math objects are advanced application objects that can execute mathematical operations on
data points. A math object takes a number of input data points (variables v
1
, v
2
, …, v
n
) and
calculates a result value according to a specified formula. When configuring a math object,
the input data points, output data points and the formula must be configured by the user.
Input data points can be configured with a change-of-value condition, to trigger the math
calculation only if the value changes more than a certain delta.
To Create a Math Object
1. Under the Global Objects folder, select the Math Object sub-folder.
2. Right-click and select New Math Object … from the context menu.
3. In the Create New Math Object dialog, enter a name and optionally a description for
the math object.
4. Attach input data points by clicking the Add Input DP button.
5. In the data point selector dialog, select the input data points and click OK. The data
points appear as v1, v2, etc.
6. If the data point shall trigger the math calculation only after a certain change-of-value,
enter a value into the COV delta column.
7. Select the input data point and click Add Variable to push the variable on the
evaluation stack.
