Chapter 5 Predict System Performance
Explicit Messaging
The RSView® and PanelView Plus messages are explicit messages. Reserve 10% of
the bandwidth of the EtherNet/IP communication module for explicit
messaging.
Explicit messaging throughput is also dependent upon network availability and
target availability. Therefore, reserving 10% of the total bandwidth does not
guarantee throughput.
Next determine if each EtherNet/IP communication module has enough
bandwidth to handle the implicit messaging.

1756-EN3TR The pps for these modules depends on the
module’s series and firmware revision.
The modules support this pps:
• Series A, firmware revision 2.x or earlier
= 10,000 pps
• Series A or later, firmware revision 3.6 or
later= 25,000 pps
For more information on the pps supported
by these modules, see
Table 12 on page 66 .
One of the following:
• Series A, firmware revision 2.x or earlier
= 1000 pps
• Series A or later, firmware revision 3.6 or
later= 2500 pps
