Data Exchange with ModuleInterface

Overview

If you want to exchange data with the robot, there are several ways to accomplish this.

The most efficient way is via ModuleInterface.

Add a variable to ModuleInterface:

Step	Action
1	Open the ModuleInterface. 1 STANDARD_INTERFACE 2 USER_INTERFACE 3 Textual view 4 Tabular view The ModuleInterface provides two sections: STANDARD_INTERFACE (1) and USER_INTERFACE (2).
2	Add variables in the: Textual view (3) or Tabular view (4)
3	If you add VAR_INPUT, VAR_OUTPUT or VAR_INPUT_OUTPUT you must update the call of the robot.
4	If you use the Code Generation Option for Non Template Robots, the call of the robot is updated automatically.

Step	Action
1	Right-click the Robot ... -Series object to add, for example, a method.
2	You can use the method to set/get data of the robot.

Step	Action
1	Add a global variable to use it inside and outside of the robot.
2	As Data type you can use the standard data types (BOOL, LREAL, ...) or user-defined data types (for example ST_MyStruct).

Variables, which have been defined in methods are volatile and are reinitialized with each call of the method.

If you need nonvolatile variables to save data, you must define the variables in the ModuleInterface.
