4.6.4.2 DC Input Operation
The General I/O Port provides sixteen 24 Vdc inputs.
There are two groups of eight inputs: group A = input 1
through output 8, group B = input 9 through output 16.
Each group can be configured as sourcing or sinking.
Connect the DCSS pin (DCSS1 for Group A, DCSS2
for Group B) to IO24C for a sourcing configuration.
Connect the DCSS pin (DCSS1 for Group A, DCSS2
for Group B) to +24 Vdc for a sinking configuration. An
example of connecting input devices in both a sink and
source configuration is shown in
Figure 4-6 .
In addition, the first input of each Group (Input 1 of
Group A, and input 9 of Group B), can be programmed
to provide a processor interrupt on either a low-to-high
or high-to-low transition.
For more information on DC input operation, refer to
Section A.2 on page 171 of Appendix A .
