Multicast Connection Options
Minimum RPI
Use the default of 0.2 ms.
Maximum RPI
Use the default of 536870.9 ms.
Provide Default RPI to Consumer for Out-of-Range
Requests
Click the check box to allow a producing tag to
provide an RPI to a consuming tag whenever a
consuming tag has an RPI that is outside the
range of the producing tag. The consumer then
connects with the RPI provided by the producer if
set up for this functionality.
If the check box is cleared, the producing
controller will not return to the consumer an RPI
value that is within the producer’s RPI range.
Default RPI
Type a value that the producer will provide to the
consumer when the consumer’s RPI falls outside
the range of the producer’s RPI settings. The
above check box must be checked for the
producer to provide the default.
3. Click OK.
The Produced Tag Connections dialog box appears.
4. Click OK.
Important:
The RPI Limits configuration, which is disabled when online, must be within:
•
Minimum RPI: 0.196 ms.
•
Maximum RPI: 536870.911 ms.
•
Default RPI: configurable within the minimum/maximum range.
•
1769-L2x and 1769-L3x controllers: see
RPI limitations and negotiated default
for
additional instructions.
The RPI limits apply only to multicast connections on unscheduled networks. This functionality is
not supported on the ControlNet network.
Unicast connection options
Unicast connections are point-to-point connections between a producing
controller and consuming controller; no multiple connections. You do not have to
enter a minimum or maximum RPI range or default value for this type of
connection.
The Allow Unicast Consumer Connections check box at the bottom of the
Advanced Options dialog box defaults with a check mark. Click OK to complete
setting up the producing tag.
