8. Click Manual Mapping . In the CHPID Groups tab, observe any intersect warnings that were found during automatic mapping and decide whether they are acceptable (see Figure 4-37). The example returned the “C” intersect. This warning indicates that multiple definitions exist on the same I/O card.

You can now display the results of the channel mapping. You can also sort the report in various ways. For example, you can see how the CHPID Mapping Tool ranked control units. 

Complete the following steps to check and set values for items, such as OSC CHPIDs and FCTC CHPIDs, to ensure that the CHPID Mapping Tool allocates these CHPIDs with high CHID availability: 

1. Click CU Priorities . By default, this pane is in the center at the top of the window. 

2. In the CU Priorities pane, search in the CU Number column for the control units for which you want to set a priority. 

3. Enter a priority number for the CU in the Priority column for each row. The CHPID Mapping Tool makes more related changes in the CHPID Groups panes.
