point manager will connect to one of these scheduler objects. There may be more
scheduler objects available on the device than are actually used at a certain time. It is a
good idea to have some spare scheduler objects ready, in case another scheduler is
needed.
• Number of daily schedules: This is the maximum number of schedules supported by
each scheduler object. This number must at least be 7, since a scheduler always needs
to provide one schedule for each day of the week (default weekly schedule). For each
special day defined by the calendar or embedded exception day, an additional daily
schedule is required to support it.
• Entries in Time/Value table: This is the total number of entries in each scheduler
defining a value template that should apply on a specific day starting at a specific time
(the time table).
• Number of value templates: This is the maximum number of value templates
supported by each scheduler.
• Data size per value template: This specifies the buffer size reserved to hold the data
for each value template. More data points or bigger data structures require a bigger
value buffer.
• Max. number of data point maps: Specifies the maximum number of individual data
points that this scheduler is able to control.

As can be seen from the above list, it is not easy to configure a LONMARK scheduler object.
There are many technical parameters which need to be set and which require some
knowledge of how these scheduler objects work internally. Therefore, the configuration
software provides the following mechanisms to help in choosing the right settings:
• Resources required by the current project: The absolute minimum settings required
by the current project are shown in a table at the left side of the window. This data may
be used to fill in the values at the right side, but some additional resources should be
planned to allow for configuration changes which need more resources.
• Auto-Set: This button may be used to let the configuration software decide on the best
settings to use, based on the current project. Since the current projects resource usage
is taken as a starting point, all schedulers and calendar patterns in the project should
first be configured as required before this button is used.
