LOGO! TD function keys
The LOGO! TD has four function keys that you can use in your circuit program. You program
these keys in the same way as other inputs. Like the cursor keys, you can press these keys
when LOGO! is in RUN mode to affect the behavior of the circuit program, and to save
switches and inputs. They are identified as F1, F2, F3, and F4.
Levels
Voltage levels are designated hi and lo. A constant "1" = hi or "0" = lo status at the block can
be set by means of a permanent voltage level or constant value hi or lo.
