Using Button Input Bits (B) Section 3-14
Using Button Input Bits
• The buttons can also be used as “hidden keys” for software resets of counters or
holding bit present values.
Press the DEL+ALT Buttons simultaneously
during operation to reset the counter C2
present value to 0 and the holding bit H5 to
OFF.
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).
