Association of user variables to physical inputs/outputs

It is possible to associate user variables (variables that are used in part programs) to physical inputs or outputs of the D410-2 control unit.

In Table 1, you find all the digital inputs and outputs of the D410-2 control unit that can be used to send or receive signals from outside.

Table 1: List of physical inputs/outputs that can be used on the D410-2

In addition to these Boolean inputs/outputs, there are three other inputs that can be associated to variables. These inputs are of LREAL type and must be associated to variables of the same type.

Table 2: List of LREAL inputs

The inputs "Actual measuring sensor position" and "Actual force value" are inputs that are already connected to the measuring sensor and the force sensor respectively. The "Actual axis position" input is not a physical input, but an internal value of the control unit.

When associated to a variable, these three values can be read from the part-program.

Create the association of a variable to a physical input/output

Before a user variable can be associated to an input or output of the D410-2 control unit, this user variable must be created (see the chapter "Declaration of user variables").

As soon as the variable is created, please follow the steps below to associate this variable to a physical input/output of the D410-2.

1.In the project tree, open the "Hardware" tab and double-click on the "D410" tab. The window below opens.

Figure 1: Window for associating variables to inputs/outputs of the D410-2

2.Select the input or output of the D410-2 to be associated to the user variable. To do this, click in the "CheckBox" of this physical input/output. (see figure 2 below).

Figure 2: Selection of input 2 (DI2)

3.Use the drop-down list to select the variable to be associated to this input/output.

Figure 3: Selecting the variable to be associated

4.For the association to be effective, load the project into the D410-2 control unit .
