6.4. Device Variables
The I/O data (process data) for Photoelectric Sensor are allocated to the Controller's device
variables as PDO communications data. The device variables are named automatically from a
combination of the device names and the port names.
The device variables and the data types are shown below.
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 document, the data type is simplified by displaying BOOL[16].
(The example above means a BOOL data type with sixteen array elements.)
