9.2.2 Comm/FC Logger
The Comm/FC Logger (Figure 9.4) captures Modbus requests and responses to/from the DCS
and MOVs (channel A & B). Additionally, the Logger screen shows configuration changes related
to channel A and/or B, Ethernet, and DCS port activity, as well as individual function codes. The
channels can be selected individually to filter activity being displayed.
NOTE: The Comm/FC logger is designed for local diagnostic purposes only. While the Comm/FC
logger is active, communication from the DCS/host device to the Master Station III is subject to
reduced performance.

9.2.3 Polling Statistics
The Polling Statistics screen (Figure 9.5) allows the user to view the polling history of each activated
MOV on the network. This diagnostic feature reveals the total number of polls, errors encountered,
and error rate (%) during a user-defined time frame.
