application may override the unsupported packet interval with a supported packet
interval. When this occurs, the new ‘effective’ value is displayed separately next to
the unsupported value that was entered.
Similar to other controllers, the 1769-L2
x and 1769-L3x controllers will verify
that the RPI of incoming connections are within the produced tag settings. If the
consuming tag’s RPI falls outside the configured range, a producing controller will
reject the incoming RPI and then provide an RPI (default) to the consuming
controller.
Important:
The producing and consuming controllers must be set up to allow the consumed tags to use an
RPI provided by the producer. See
RPI limitations and negotiated default
for procedures to set up the producer and consumer tags to accept a
negotiated default RPI.
For the 1769-L2
x and 1769-L3x controllers, the Effective Minimum RPI, when
present, is used to determine the fastest packet interval allowed by the tag. When
the Effective Default RPI is present, it is the largest packet interval (slowest rate)
at which negotiated connections will be produced for the tag.
The effective RPI limit values are presented with a flag on the Advanced Options
dialog box to indicate that RPI limits are set to values other than what you
entered.
