How does the program know when a keypad entry is complete?

When a keypad entry is complete, there are special SBs that go to logic 1 for one system scan.

If there is more than one Variable on display, there is an HMI Var Keypad Entry Complete SB for each Variable.

The SBs are:

  • SB 30 - HMI Keypad entries complete

  • SB 31 - HMI Var 1 Keypad entry completed

  • SB 32 - HMI Var 2 Keypad entry completed

  • SB 33 - HMI Var 3 Keypad entry completed

  • SB 34 - HMI Var 4 Keypad entry completed

You can use these special SBs in your Ladder project or Jump conditions to move from Display to Display when keypad entry is complete.
