PLLS motor preferences

Use the
Motor preference
tab on the
PLLS Properties
dialog box to configure preferences for the motors included in a group for Process Lead Lag Standby Motor Group (PLLS) instructions.
Motors start in order of preference from 1 to 30.
TIP: When configured, motor priorities override motor preferences.
To configure motor preferences for PLLS instructions
  1. On the instruction in the routine, perform one of these actions:
    • On the Ladder or FBD instruction, select .
    • In the Structured Text editor, right-click the tag name and select

      .
  2. Under
    Advanced
    , select the
    Motor preference
    tab.
  3. In the
    New
    box for each motor, enter a preference number. The motor with preference 1 starts first, followed by 2, and so on. The existing preference value for each motor appears in the
    Current
    box. If the Cfg_CnfrmReqd parameter equals 1, a confirmation message appears that asks you to confirm the updated setting. If the setting requires a signature, this will enforce security from the HMI and disable the setting from the Logix Designer dialog.
