Object type Phenomenon
Word Part
The part screen set in the object is not shown.
But if communication is set with other object in the same part screen, it can be
shown by that object.
Animation Animation is not shown.
Bar Graph
Graph is not shown. When designating the background image, image is shown as
it is.
Pie Graph
Graph is not shown. When designating the background image, image is shown as
it is.
Meter Graph
Graph is not shown. When designating the background image, image is shown as
it is.
Closed Graph
Graph is not shown. When designating the background image, image is shown as
it is.
Trend Graph
X, Y axis is shown normally but trend axis is not normally shown.
When designating the background image, image is shown as it is.
History Alarm Viewer
Change doesn’t occur. When communication is abnormal, alarm occurs because it
can’t know the status of alarm target device. But previous alarm data shows up as
it is.
Data list Value is not shown. Lattice of viewing data list of object is shown as it is.
Logging Viewer
Change doesn’t occur. When communication is normal, the recorded log data is
shown normally. But, log data is shown as # when communication is abnormal.
Navigator
Change doesn’t occur. Because it shows the group of alarm already developed,
though communication is abnormal, if it has alarm data already developed, it
shows the name of group where each alarm is included.
Question
The number indication object value is shown as # or ~
Phenomenon
The number indication object value is shown as # or ~.
(Same phenomenon occurs at the number input device, viewing data list, and viewing logging)
<Cause>
(1) This happens when digit is not correct or type is not BCD.
<Solution>
(1) When the number to be expressed exceeds the number set in the object, # is expressed. In case of this,
set the digit largely and after download again, execute program again.
(2) When the numeric display object is expressed as BCD type, the data whose type is not BCD is
expressed as ~. In case of this, adjust device value as BCD type.
(3) This phenomenon occurs at the data list object, numeric input, numeric display device, and logging
viewer.
