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).
