Configuring an Ember+ Provider
"System -> Definition -> Parameter = Local Providers"
An Ember+ Provider publishes parameters so that they may be controlled by an external consuming device.
Up to five Ember+ providers can be defined in the "System -> Definition -> Parameter = Local Providers"
branch of the 'Tree Definition' window. The Provider number (1 to 5) will be referenced by other elements. For
example, from an
Ember+ GPIO
each external device.
Select "System -> Definition" in 'Tree Definition' and the Ember+ tab to access the "Local Providers"
options:
Parameter
Local Port Number
Task Priorities
Enable Subscript Reports This option determines whether the Ember+ Provider will announce value changes to
crystal User Manual
or
Source
element. This allows you to change what can be accessed from
Local Providers – reference name for the element.
Enter a port number. This must match the Port Number of the Ember+ consumer:
·
If the consumer is configured using the ON-AIR Designer, then enter the
Number
defined in the consumer's configuration.
·
If the consuming device is another system type (V_pro8, Orban, etc.), then you will need to
find out the Ember+ control port number from the relevant documentation.
This option can be used to raise the priority of the Ember+ Provider, when compared to DMS
and network communications (such as GNET). The default setting of normal is
recommended, as changing the priorities may affect the overall system performance. The
options are:
·
normal = the Ember+ provider has low priority. Interference of different functions is
minimal. When executed, Ember+ functions may be delayed.
·
high = the Ember+ provider is prioritised above DMS. Ember+ functions are executed
faster. There may be delays to DMS functions like VisTool metering updates or VisTool
control.
·
highest = the Ember+ provider is prioritised above DMS and TCP/IP link communication:
AIF, KPF, GNET, etc. In addition to the effects described above (for high), the setting of
crosspoints via GNET may be delayed.
connected consumers. When ticked, values are announced (required for bi-idirectional
Ember+ Source
Replication). When not ticked, values are not announced; this can be used to
reduce the volume of network traffic.
