6.4.3 Ethernet Performance
Ethernet performance on the MVI56E-MCMR module can affect the operation of
the MCMR application ports in the following ways.
 Accessing the web interface (refreshing the page, downloading files, and so
on) may affect MCMR performance
 High Ethernet traffic may impact MCMR performance (consider CIPconnect
(page 94) for these applications and disconnect the module Ethernet port
from the network).
