Data Menu 19
This drop down list box allows you to select any of the active topics. A preceding ‘*’
indicates that at least one item in this topic has an error while a preceding ‘#’ indicates
bad status.
This field displays the current configured update interval of the topic. This value
changes whenever the value is poked via I/O. The displayed value is the
UPDATEINTERVAL item value.
This field displays the current update interval of the slowest item of the topic. This
value is measured for each poll cycle and each received cyclic service indication. If this
value drastically differs from the desired update interval the communication media is not
fast enough to satisfy the load. The displayed value is the MAXINTERVAL item
value.
Note Both values: update interval and longest interval are accessible via I/O. You can
create an WindowView performance meter by displaying these values graphically for
each topic. If I/O access is enabled, you can even tune the bus performance
conveniently from WindowView.
This line shows the available PDU size for this topic. The larger the value, the more
data can be send in one message.
This field displays the number of active items and the number of items with errors (in
parenthesis). If you check this box, only items with errors will be displayed in the item
data list box.
The item list box adapts to the size of the dialog box. So you can resize it for your
personal needs. The server will save the size and position.
