necessary to operate the device with some network management tools that do not
support the ECS.
Default Pollcycle for External NVs
: When using external NVs, this poll cycle is set as
a default for input data points. The poll cycle can be edited individually in the
properties view of the data point manager.
Use state-member of SNVT_switch as
: This setting defines how the state member of
the SNVT_switch shall be mapped to a data point. Depending on how the data point
shall be used, it can be binary or multi-state. The multi-state setting allows setting the
UNSET state explicitly. As a binary point the UNSET state is implicitly chosen, if the
value is invalid.
Omit unused child data points of UNVT/UCPT structures
: This setting defines, that
if set, also unsued sub-data points of user-defined structure types are not downloaded
onto the device. This option can reduce the total amount of data points in the
configuration. As a default it is not enabled to allow full structure information after an
upload to the PC even if the user does not have the original resource files installed.
Configuration Download
: This group box contains self-configuration settings for the
CEA-709 ports. This is necessary if the device shall be used without being
commissioned by a network management tool. Set the check mark and enter the
CEA-709 domain and subnet/node information. If operated in self-configured mode,
the CEA-709 network can be scanned using the network scan (see Section 6.7.4) and
external NVs can be used on the device. Note, that the domain must match the nodes‘
domain on the network and the subnet/node address must not be used by another
device.

6.3.4 AST Settings
For CEA-709 devices, the use of alarming, scheduling, and trending (AST) features requires
additional resources (functional objects and NVs). This changes the static interface. Since
the number of used resources also influences the performance, the CEA-709 AST tab allows
configuring those resources for the project. In this tab, the required number of scheduler
units that may be instantiated and their capacity may be configured (how many time/value
entries, value templates, bytes per value template, etc.). It contains the following options
and settings, which are relevant to calendar and scheduler functionality of the device:
Enable Calendar Object:
This checkbox enables a L

M
ARK
compliant calendar
object on the device. It is automatically enabled together with local schedulers, since
the two are always used together.
