3.5.3.1 Tag group name
Specify a valid name for the tag group element. The name has to be unique among its
siblings and may not contain white spaces or non-alphanumeric characters. The only
exception is the underscore character "_".
3.5.3.2 Time stamp address for all tags in the group
Reading values, the OPC Server sends OPC Client application information on the value,
quality, and time stamp of a tag item.
The tag's time stamp will be set to the PC time when the tag value was read from the
PLC. Instead of using the PC time for the time stamp, the time stamp can be specified
by a DATE_AND_TIME variable in the PLC program. If you enter the address of a PLC's
DATE_AND_TIME variable, the OPC Server will read the time stamp value from the PLC.
The following diagram illustrates this process.
