Default (standard) mappings

Standard mappings are mappings that can be automatically set up by the simulation manager in one step. An automatic mapping offered for symbols that are available both in the original PLC and in the simulation PLC (with the same data type) is created by calling the main menu item 'Create Default Mappings' from the 'Edit' menu (see Figure 1).

This functionality iterates over all Symbols within the original PLC projects and tries to bind it to simulation symbols of the same symbolic name / access path, same data type but reversed location (reversed %I / %Q). If an applicable simulation symbol exist, an local (IO-Mapping) or remote Mapping (via Realtime Network Variables) will be created within the simulation settings.

Standard mappings are very useful when used in conjunction with the Create Simulation project feature. This feature ensures that the symbolic names and access paths within the simulation project are easily connectable to the original PLC project for the user and automatic program support by ensuring identical naming conventions.

In Figure 2 the navigator window has the original Symbol 'bRun' selected. The 'Simulation Targets View' on the right hand side shows the possible connections within the assigned simulation PLC project. The Default Mapping for this symbol is 'MAIN.bRun' and is marked with green text.

If the default connections are generated, the original symbol MAIN.bRun will be bound to the simulation symbol 'MAIN.bRun' for the simulation profile (see Figure 3). Simulated Symbols will be marked with the red 'S' within its icon to show that a simulation setting is assigned.
