Inputs, Outputs, Timers, and Other Control Logic
Rotating Default Display (Only on Models With LCD)
This results in the continual display of text setting DP5_1 on the front-panel
display:
This can also be realized with the following settings:
DP5 = 0 (set directly to logical 0)
DP5_1 = (“blank”)
DP5_0 = LINE 1204 (displays when DP5 = logical 0)
This results in the continual display of text setting DP5_0 on the front-panel
display:
Active Setting
Group Switching
Considerations
The SELOGIC control equation display point settings DPn (n = 1–16) are
available separately in each setting group. The corresponding text settings
DPn_1 and DPn_0 are made only once and used in all setting groups.
Refer to Figure 7.30 and the following discussion of an example setting group
switching discussion.
Setting Group 1 Is the Active Setting Group
When setting Group 1 is the active setting group, optoisolated input IN102
operates as a reclose enable/disable switch with the following settings:
SEL
OGIC control equation settings:
79DTL = !IN102 + ... [= NOT(IN102) + ...; drive-to-lockout setting]
DP1 = IN102
Text settings:
DP1_1 = 79 ENABLED (displayed when DP1 = logical 1)
DP1_0 = 79 DISABLED (displayed when DP1 = logical 0)
Reclosing Relay Enabled
In Figure 7.30, optoisolated input IN102 is energized to enable the reclosing
relay, resulting in:
DP1 = IN102 = logical 1
This results in the display of corresponding text setting DP1_1 on the front-
panel display:
LINE 1204
LINE 1204
79 ENABLED
