• Refresh
Pressing this button will read all counters from the module. This operation takes place immediately
and only happens once each time the button is pressed. This button is not available if the Continuous
Update checkbox is checked.
• Clear
Pressing this button will clear all counters in the module. This is often useful to see the affect of a
change to the system. For example, suppose you change your controlling PLC's ladder logic and
want to see its affect on the transfer rate. You may want to first start the ladder logic and then clear
the statistics to avoid confusing old data with the new.

Each counter is described below:
General
Note: Each of these counters is limited at 4,294,967,296, and if it reaches this value, then it will
wrap back to zero and resume counting from there. This generally will only occur on the Total
Bytes Received and Total Bytes Sent counters.
• Total Bytes Received
This is the count of all bytes in all packets received by the RMC whether directed to either the
RMC's MAC address or the broadcast MAC address (FF FF FF FF FF FF). Packets discarded
due to the Rx Errors described below are excluded from this count, but all other packets are
included, even if discarded for other reasons. NOTE: When this counter reaches 4,294,967,296, it
will wrap back to zero.
• Total Valid Directed Pkts Rcvd
This is the count of all packets received by the RMC that were directed to the RMC's MAC
address, and were processed. This does not include packets received but discarded due to
protocol errors such as invalid protocol, IP address, or destination TCP/UDP port.
• Total Valid Broadcast Pkts Rcvd
This is the count of all packets received by the RMC that were directed to the broadcast MAC
address, and were processed.
• Total Discarded Directed Pkts
This is the count of all packets received by the RMC that were directed to the RMC's MAC
address, but were discarded due to invalid protocol, IP address, or TCP/UDP port.
• Total Discarded Broadcast Pkts
This is the count of all packets received by the RMC that were directed to the broadcast MAC
address, but were discarded due to invalid protocol, IP address, or TCP/UDP port.
• Total Bytes Sent
This is the count of bytes sent by the RMC over the Ethernet. NOTE: When this counter reaches
4,294,967,296, it will wrap back to zero.
• Total Directed Pkts Sent
This is the count of packets the RMC sent to a specific MAC address. This is typically done by the
RMC only in response to a request from another device.
