Figure 6 - Generate Events for Binary Input Object
Click Add to select, or create a binary variable from the variable selector screen for the Binary
Input Object.
There are two methods to create Binary Input Object. You can create the object as a BOOL data
type or as an UINT data type. The UINT data type represents similar to a BOOL array of 16 bits
and this representation is similar to the BOOL array used in MicroLogix™ 1400 controllers.
The setting in the image above shows that the different class events can be triggered when
the BOOL variable is triggered. When using the UINT variable, any of the bits in the UINT will
trigger the respective class event.
