Create Logic in the New Ladder Editor Chapter 7
When you add an instruction to your logic, all outputs of this
instruction are added to the Tag Database automatically. Choose
Tools > Show Tag Database to open the window. In the Tag
Database, you may modify the alias names of the new tags, edit
forcing options (if the device supports forcing), select data types, and
select fault options.
When you add an instruction to your logic, a tag name is
automatically assigned (its default alias name), following the naming
rules: [InstructionName_Index], where Index is numeric and
automatically increases by 1 when you add a new instruction of the
same type to your logic. If you delete an instruction from your logic,
this Index number becomes available for new instructions (of the
same type) that you add to your logic.
Output tag names are assigned as follows: [Instruction name.Output
Name]. For example, Timer_1.DN refers to the output for Timer 1.
