Main

Block Transfer Statistics
screen.
Use this command to display the configuration and statistics of the backplane
data transfer operations between the module and the processor. The information

the processor and the module.
Tip:
To determine the number of blocks transferred each second, mark the numbers displayed at a
specific time. Then some seconds later activate the command again. Subtract the previous
numbers from the current numbers and divide by the quantity of seconds passed between the two
readings.
