Rockwell Automation Logix5000 Controllers Produced and Consumed Tags Programming Manual - Manual (Page 28)

Chapter 1 Produce and Consume a Tag
Scenario 4
The RPI is outside the range of the producing controller’s RPI Limits. A default
RPI is set up for the producing controller. The consumer is set up to accept the
RPI provided by the producer.
Version 17 and earlier: The RPI requested by the consumed tag is not within the
range of the producer. The connection is rejected and a 0112 error is reported that
the connection failed. You must re-enter an RPI that is within the range
configured on the produced tag. If a version 17 consumer is trying to connect with
a version 18 producer and the RPI is outside the range of the producer, a 0112
error reports the connection failed.
Version 18 and later: The RPI requested by the consumed tag is not within the
RPI limitation range of the producer. The producer is configured to provide an
RPI default. The producer sends the default RPI to the consumer. The consumer
is set up to accept the RPI provided by the producer. The connection is successful
and the multicast connection accepts the new RPI of 5 ms.
All controllers, with the exception of the CompactLogix 1769-L2 x and 1769-L3x
controllers, produce data in packet intervals ranging from 0.196…536870.911 ms.
The 1769-L2
x and 1769-L3x controllers produce only in packet intervals of 2, 4,
8, 16, 32, 64, 128, 256, 512, or 1024 ms.
You are not confined to entering these exact values when configuring an RPI
limitation range and default RPI for the 1769-L2
x and 1769-L3x controllers.
However, if an unsupported packet interval is entered, then the Logix Designer
