This page shows current information for open TCP connections on port 502: b Messaging Statistics: this field contains the total number of sent and received messages on port 502. These values are not reset when the port 502 connection is closed. Therefore, the values indicate the number of messages that have been sent or received since the module was started. b Active Connections: this field shows the connections that are active when the Messaging page is refreshed. QoS (quality of service) page This page displays information about the QoS service. This service is configured in EcoStruxure Control Expert (1) . When QoS is enabled, the module adds a differentiated services code point (DSCP) tag to each Ethernet packet it transmits, thereby indicating the priority of that packet. Network Time Service page This page displays information about the NTP service. This service is configured in EcoStruxure Control Expert (1) . The Network Time Service synchronizes computer clocks over the Internet for the purposes of event recording (sequencing events), event synchronization (triggering simultaneous events), or alarm and I/O synchronization (time-stamping alarms). Field Description Service Status Running The NTP service is correctly configured and running
