6.4. Device Variables
The process data of the Signal Tower (as PDOs in the Slave Terminal) is assigned to the
Controller's device variables. The device variables are automatically named from a
combination of the device names and the port names.
The following show the device variables and data types to which the process data of the
Signal Tower is assigned.
In this guide, the operating mode of the Signal Tower is set to Simple Mode (default) for the
process data assignment of the Signal Tower.
Additional Information
With Sysmac Studio, two methods can be used to specify an array for a data type.
After specifying, (1) is converted to (2), and the data type is always displayed as (2).
(1) BOOL[16] / (2) ARRAY[0..15] OF BOOL
In this guide, the data type is simplified by displaying BOOL[16].
