This is the interface from the Siemens Power TG EMS system. The problem is with the saving of Alarm and Event text messages. There are instances when the data files are produced out of order. When data is sent out of order the interface seems to go into arcnoreplace mode and our data is lost.
To store Alarm and Event messages, the duplicate record check is turned off so there is no way to overwrite data, therefore the arcnoreplace is a meaningless protection. Data will never be over written.
