When events are read as a PLC Tag, they are returned as a String in the format <timestamp in seconds><channel>E<event code>. In case of an error, to retry the reading of an event, users must read the backup buffer. For more information, please check the Last Event of the Backup Buffer PLC Tag and the Last Events of the Backup Buffer Block Tag. Data type of the Value property is a String. The Timestamp property of this Block Tag contains the timestamp returned by a device, which corresponds to the first field of the String from the Value property.
