9.6.2 Use of network communications filters
Overview
It is recommended to use the available comms filters to minimize the network
communications data traffic of commands as well as events to that which is necessary. This
is done to optimize the use of the bandwidth and buffer sizes, which are limited by physical
constraints. The panel can buffer a total of 484 events (including points, zones, system
status). Once this buffer is full information is no longer passed to Maestro and panel events
that are inter-panel I/O mapped will also not be sent. In the case of viewing ‘Disables’ some
of the buffer space may be occupied by other events that occurred since the last reset,
including reset status events from remote panels, if they were configured to send them.
In particular the “Disabled/Enabled” status of points and zones is now passed to Maestro
primarily by General Status data blocks (controlled by the General Status Filter), and no
longer depends on the Disabled Event telegrams, which bypasses the restriction in event
buffer size and contents.
The General Status data block is sent automatically by the panel to Maestro 20 seconds
after a single change in its disablements, (or once 20 seconds after the last of a series of
disablements). It is also requested by Maestro automatically on startup, after a reset, during
a fascia view or manually on request by the operator by selecting “refresh”, or “current
status” (from Maestro Comms or Maestro Panel Controls-Right click).
Fetch Disables Control
The Fetch Disables command filter setting can be toggled by selecting key 4, in the KEYS
options. This filter enables/disables the Fetch Disables command to the individual remote
panels when the View Disables button is pressed on the local (receiving) panel. It
simultaneously allows/disallows the Common Disable LED from reflecting the disables of the
same remote panels.
The Comms Test message is also enabled/disabled by this filter. This is used by panels at
bootup to request the disable status of the remote panels. It must be enabled to a Maestro
station.
Disable Events
The Disabled Event filter (which existed on earlier versions) may be set separately at the
sender panel (as before) to allow or prevent volunteering disabled events to remote
panels/Maestro. It is now recommended that the disabled events filter be set to NOT send to
Maestro, and only to panels if they definitely require it.
Where a panel is undergoing commissioning / configuration changes and has large numbers
of disables, it is recommended that either the disables commands and disabled events are
disallowed, or the whole panel is “ignored” using the Panel Comms Enable/Disable feature.
General Status Events
The Gen.Status filter setting works similarly by pressing key 4 in EVENT options. This should
be used for enabling a Status data message from a panel to a Maestro, and disabling it to all
remote panels, which do not require it.
