Using Button Input Bits (B)
Using Button Input Bits
• The buttons can also be used as "hidden keys" for software resets of counters or
holding bit present values.
Note
• When a button is pressed, e.g., to make a menu selection, the operation defined for
the button in the ladder program as a button switch (B) will also be executed. This
may cause unexpected results, such as an output turning ON/OFF. Be sure to test
the program completely.
• The ESC+OK Buttons are used to switch menu displays. We recommend not using
these as button switches (B).
