Text Display function keys
The Text Display 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 IDEC SmartRelay 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.
Open connectors
Unused block connectors can be identified with an x.
