Rotating Default Display
Figure 11.8 demonstrates the correspondence between changing display point
states (e.g., DP2 and DP4) and enabled display point labels (DP2_1/DP2_0
and DP4_1/DP4_0, respectively). The display time is equal to global setting
SCROLD for each screen.
The display point example settings are:
DP2 = LB1 (local bit LB1)
DP4 = IN101 (optoisolated input IN101)
Local bit LB1 is used as a recloser enable/disable. Optoisolated input IN101 is
used as a circuit breaker status input (a 52a circuit breaker auxiliary contact is
connected to input IN101; see Optoisolated Inputs on page 7.3).
