LOYTEC L-Gate - Real-Time Keeper Object; Calendar Object; Scheduler Object; Clients Object

L-Gate User Manual 144 LOYTEC
Version 3.2 LOYTEC electronics GmbH
• nciEarthPos (SNVT_earth_pos): This configuration property can be used to set the
earth position of the L-Gate. It has been implemented as an NV to make other devices
send that configuration to the L-Gate over the network (e.g., from a GPS device).
7.2.4 Real-Time Keeper Object
When the scheduler objects are enabled in the project settings, the L-Gate includes the
standard L
ONMARK real-time keeper object. The Real-Time Keeper Object is used to
synchronize the system time of multiple LonMark compliant devices.
The object has the following network variables:
• nvoTimeDate (SNVT_time_stamp): Propagates the devices current system time and
date (local time). It is typically bound to the nviTimeSet input network variable of the
node objects of the LonMark compliant devices, which are synchronized with the
system time of the L-Gate. The update rate of the nvoTimeDate can be configured
using the configuration property SCPTupdateRate (default every 60 seconds).
7.2.5 Calendar Object
When the scheduler objects are enabled in the project settings, the L-Gate includes the
standard L
ONMARK calendar object.
7.2.6 Scheduler Object
When the scheduler objects are enabled in the project settings, the L-Gate includes the
configured number of standard L
ONMARK scheduler objects.
7.2.7 Clients Object
When the remote AST object feature is enabled in the project settings, the L-Gate includes
a proprietary object, which is a container for network variables required to implement the
remote object features.
For remote schedulers and calendars, nviSchedLink and nviCalLink NVs are created. For
alarm clients nviAlarm_2 NVs are created.
7.2.8 Gateway Objects
The L-Gate contains eight proprietary Gateway objects. These are containers for all NVs,
which are configured on the L-Gate’s CEA-709 port. They are intended for grouping NVs.
When static NVs are created, they can be assigned to any of the eight gateway blocks.
When creating dynamic NVs in the LNS-based tool, the NVs should be added to the
gateway blocks.
7.3 BACnet Interface
7.3.1 Device Object
The BACnet interface provides one device object as shown in Table 10.
