a.
• RPI: Select the desired update rate. A commonly-used RPI is 20.0 ms.
Very low RPIs may flood the network and reduce network reliability.
• Input size: This is the size of the data being produced by the RMC. In
this example, we’ll send 10 registers from the Indirect Data Map, plus
one Sync register. Each RMC register is 32 bits, or 4 bytes, for a total
of 44 bytes.
• Input mode: Most EtherNet/IP applications do not share the data
produced by the RMC and, therefore, the Input mode should be set to
Point to Point to reduce network traffic, but this can be set to Multicast
if required.
• Output size: This is the size of the data being consumed by the RMC.
In this example, we’ll consume 11 registers by the Indirect Data Map,
plus one Sync register. Each RMC register is 32 bits, or 4 bytes, for a
total of 48 bytes.
Click OK when done.

8. Download the configuration to the PLC.
a. On the PLC menu, click Connect.
b. On the PLC menu, click Transfer Project to PLC.
The above steps will register EtherNet/IP I/O connections for each RMC with the
Schneider Electric Ethernet communication module and create derived variables in the
Schneider Electric PLC representing the data for each RMC. The following screen shot
