converts the NV into IEC61131 compliant data types, is located in the folder
From_CEA709_Types
. Technology Converters to set up NVs based on IEC61131
data types are grouped in the folder
To_CEA709_Types
.
Figure 60 shows the three possibilities how to use NVs within an IEC61131 program.
Figure 60: Usage of NVs
If a structured NV comprises enumerations types, these enumerations are not split up by the

8.4.4 IEC61131 Program Cycle Time
IEC61131 programs are performed in a periodical manner. IEC61131 tasks are used do
control the execution of an IEC61131 program. As shown in Figure 57 several default tasks
are defined within the template project. Right click on the clock symbol and select properties
to change the cycle time of the task.
As described in section 8.4 a program instance is required to execute the IEC61131 program.
The cycle time of the IEC61131 program is controlled by the task assigned to the program
instance. In order to change the cycle time right click on the program instance and select
properties. In the upcoming window the task assignment for the selected program type can
be changed, see Figure 61.

Please take care when defining names for the tasks. The names displayed in the project view
are symbolic names, they do not correspond to the settings for the cycle time, even if the
L-INX template project use the configured cycle time as task name.
