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.
