After choosing Add or Insert Entry a dialog box will open
where you can define the variable name for the entry. The
Add Entry dialog is shown in Figure 7.
Figure 7. Process Historian: Add Entry Dialog.
You only need to enter the name of the variable for each
entry. The description of the variable will automatically be
imported by the editor from the I/O, shared variable or system
variable definitions.
A variable entry must be defined as an I/O word variable (AI,
AO, TI, DIW or DOW), a shared register, a shared floating
point register, or a system register. If you enter the name of a
local variable or a discrete variable for a variable entry, you
will get an error when you compile the function block.
After you have used the Add Entry and Insert Entry
commands, your variable entries will be listed in the Process
Historian Window like those shown in Figure 8.
