Figure 5-7
Proper response of channel 1 input bits when channel 0 output bits
are set to bit pattern A
13. In the Digital Input Panel under Input bits observe the bit pattern. Figure 5-7 shows the
proper response. (Here, bits which are on are shown in grey. They will be green on the actual
display.)
• If the observed input bit patterns are not the same as shown in Figure 5-7 , the digital
I/O is not functioning properly. Stop here, and return to the problem isolation step that
asked you to perform the General-purpose digital I/O hardware test.
• If the input bit patterns are the same as shown in Figure 5-7 , continue with step 14.
14. In the Digital Input Panel under Channels , click on channel 2 as shown in Figure 5-8 .

15. In the Digital Input Panel under Input bits observe the bit pattern. Figure 5-8 shows the
proper response.
• If the observed input bit patterns are not the same as shown in Figure 5-8 , the digital

• If the input bit patterns are the same as shown in Figure 5-8 , continue with step 16.
16. In the Digital Output Panel under Channels
, click on channel
