PINTLK interlocks

Use the
Advanced 0-15
and
Advanced 16-31
tabs on the
Process Interlocks (PINTLK) Properties
dialog box to configure interlocks for PINTLK instructions.
To Configure interlocks for Process Interlocks (PINTLK) 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
      Configure <tag name>
      .
  2. Select the
    Advanced 0-15
    or
    Advanced 16-31
    tab.
  3. Configure these settings for each interlock:
    • Interlock name
      . Enter a name for the interlock. The name appears on the
      General
      tab for monitoring.
    • OK state
      . Select the box to set 0 or 1 as the OK to run state for the interlock.
    • Can bypass
      . Select the checkbox to allow bypassing of the interlock. When in a Not OK state, an operator can bypass this interlock.
    • Enable bypass
      . Select the checkbox to bypass the interlock.
    • Must reset
      . Select the checkbox to force the interlock to remain latched until reset.
    • Stop only
      . Select this checkbox to configure the interlock to stop, but not trip, the motor.
    • Type
      . Select the type for the interlock. Configure types on the
      HMI > Type
      tab.
      NOTE: You cannot change an interlock Type if Inp_LatchDefeat = 0. You can edit an interlock Type setting only when Inp_LatchDefeat = 1.
      Some interlock types override the
      Can bypass
      ,
      Enable bypass
      , and
      Must reset
      settings. This table lists the settings that cannot be changed for each type. The impact of the type selection is based on the position in the type list (0 thru 7); the type name is not a factor in the restrictions. For example, a Type 0 Safety interlock cannot be configured as bypassable and requires a reset (cannot be configured to not be latched). A Type 6 General interlock can be configured as bypassable and can be configured as latched or unlatched.
      The
      Does NOT affect availability
      column refers to an interlock’s ability to affect the Sts_Available parameter for a device, indicating that the device is available or unavailable for control. For example, a Type 0 Safety interlock cannot affect Sts_Available for a motor, but a Type 1 Protective interlock can.
