Mobius
Chrom 20 System with Flexware

If a Phase time of 2 seconds and a Rate time of 10 seconds are assigned, then once collection
starts, data will be collected at 2 seconds, 12 seconds, 22 seconds, 32 seconds and every 10
seconds thereafter.
Note
A total of 80 tag names can be assigned to a collection group. The
Historical Collect program uses less CPU time to process one group containing
80 tag names than it does to process eight different groups with ten tag names
per group.
In the Phase field, enter the number of seconds by which the collection will be staggered.
Select the "..." to display a list of available phase values.
The Phase value choices are in two second increments from 0 to 58 seconds. The Phase field
defaults to 0 seconds for the first group added in Historical Assign, and then increments by two
seconds for each additional group added.
Note
The Phase value entered must always be smaller than the Rate value.
Select a Phase value from the list and then select OK. The selected phase value is entered in the
Phase field in the Group Configuration dialog box.
5. Select Tag Names
In the Tag name field in the Group Configuration dialog box, enter the tag name you want to
add to the collection group.
To choose from a list of tag names for the selected node click the ".." button. The standard Field
Select dialog box displays with a list of tag names and fields for the node.
To quickly search through the tag list for a specific tag, enter the beginning letters for a tag in
the Filter field. For example, if "A*" is entered, then the Filter button is selected, a list of tags
beginning with "A" is displayed.
To quickly search through the fields for a tag, select the tag, and then follow the same
procedure as in Step 2. For Historical Assign, all the tags have the same field: F_CV
When the tag and field have been selected select the OK button in the Field Select dialog box.
The tag you chose to trend is shown in the Tag name field in the Group Configuration dialog
box.
Click the Add button to add the tag to the list of Tag names.
Note
Only floating point fields (F_) can be trended.
