4.5.5 Shunt Discrete Input/Output Usage
Ballard Technology’s BTIDriver API provides functions to read and write the
discretes. The parameter dionum in the API functions (BTICard_ExtDIORd and
BTICard_ExtDIOWr) specifies which discrete to read or write.
Table 4.6 below shows the correlation between dionum and its hardware refer-
ence designator (i.e., ADIOn).
