When it comes to embedded modules connected across a backplane, the I/O is managed based on the RPI rates specified in the configuration. The minimum RPI for each module is 1ms, but this can vary depending on the number of modules and the presence of any specialty modules. It is crucial to adjust the RPI as the number of modules increases to prevent faults and overruns. According to Rockwell's recommendations, the RPI should be set at 2ms for 1 to 2 digital modules, 4ms for 3 to 4 digital modules, and 8ms for 5 to 6 digital modules. Additionally, analog and specialty modules require an additional 20ms per module. Adjusting the RPI rates accordingly is essential for optimal performance and system stability.

The data transfer rate for the CompactLogix PLC model 1769-L24ER-QB1B is not explicitly mentioned in the product specifications, but in general, the CompactLogix family data transfer is closely linked to the Ethernet/IP communication speed, which can reach up to 10/100 Mbps. The actual transfer rate can vary based on the complexity of your program, number of I/O and communication devices on your network. I recommend reaching out to Allen-Bradley or a Rockwell Automation rep for a more specific answer tailored to your usage conditions.
