{Introduction}
This article discusses the procedure for setting up a configuration for a cell with multiple robots. Creating and editing a configuration for a multi-robot cell is the same procedure as for a single-robot cell, except that a tooling mounting would need to be added for each robot.
Prerequisites

The following procedure assumes that a cell is already created and multiple robots
...
Open cell editor (Main menu > New > Robot cell)
Decide where the base frame (world) will be in the cell.

Creating a configuration
Creating and editing a configuration for a multi-robot cell is the same procedure as for a single-robot cell, except that a tooling mounting would need to be added for each robotare already loaded in it.
Create a configuration
Open the cell in the cell editor.
In the Cell tree, select the cell.
In the Cell Settings pane on the right, next to Configuration repository, select the [+]
button to add a new configuration. 
Select the Edit button to edit configuration settingsoptions.
For the first robot, set Tooling mounting options.
Tooling mounting frame: Select the tooling mounting frame for that specific robot.
Default tooling: Optional. Select the default tooling for the robot. Note that the same tooling cannot be used by different robots.
Default user frame: Optional. You can apply a default user frame to a given robot.
Select Add tooling mounting.
Set Tooling mounting options for the second robot.
Repeat steps 5 6 and 6 7 for any additional robots.
Set a Path mounting frame and Default home position (optional) as you would for a single-robot configuration. Also set other common options, as needed.
When you are finished making changes to the configuration, click OK.
You can create more than one configuration. A configuration can have as few as one robot, and as many robots as are in the cell. For example, for a multi-robot cell. For example, you could create one configuration with only one robot active and the other robots idle. Then, you could create a second configuration with all robots active. When programming a part, you could then easily select the configuration needed.
