19. Display the packet logs (Figure 10-15):
a. Click the Monitor checkbox.
b. Select a value from the Log Size drop-down list.
c. Verify that communication traffic flows between the RMC and XMV. Arrows on the log point
in two directions to indicate requests and responses between the RMC and the XMV.
Figure 10-15: XMV Interface Communications Packet Logs
IMPORTANT NOTE: A packet log that displays requests from the RMC but not from the XMV, could
indicate a baud rate mismatch, or an unpowered or damaged XMV.
When
multiple XMVs connect to the RMC and the packet log displays correct communication
exchange for some XMVs but not for others, verify
connection with the non-
responsive XMVs. If the
configuration is correct, the XMVs might be unpowered or damaged.
IMPOR
TANT NOTE: If all serial ports in the MOXA
®
module are in use, four communication
applications should be added and configured. Use one application for each port. For example,
Figu
re 10-16 shows an RMC with four XMV Interface applications configured for each of the serial
ports on a four
-port MOXA
®
module. In this example, ports 1 and 4 connect to a single XMV. Ports
2 and 3 connect to multiple XMVs
