CEL doesn't record events when loss of connection to RTU

Hello,

I've had some problems with getting events from an RTU when the RTU loses connection. The connected RTU stores the change of events when it looses connection to it's OPC gateway, zenon connects to the OPC gateway as an OPC DA client and reads the status of a point as per the screenshot attached. if I unplug the RTU's ethernet port, the RTU stores the changes of status of the IO and uppon to recconection to the gateway it "discharges" it's event log while it lost connection to the OPC gateway. I've noticed that Zenon ignores all the changes that were done while disconnected as per the attached screenshot. Is there any speacial setting that needs to be done to deal with this?
