3.1.2 Cursor keys
Up to four cursor keys are available to you. Cursor keys are programmed for the circuit
program in the same ways as other inputs. Cursor keys can save switches and inputs, and
allow operator control of the circuit program.
3.1.3 Outputs
Output blocks represent the output terminals of xLogic. You can use up to 254 outputs. In
your block configuration, you can assign an output block a new terminal, provided this
terminal is not already used in your circuit program.
The output always carries the signal of the previous program cycle. This value doe not
change within the current program cycle.
3.1.4 Permanent logical levels HI and LO
Set the block input to logical hi (hi = high) to set it permanently to logical '1' or 'H' state.
Set the block input to logical lo (lo = low) to set it permanently to logical '0' or 'L' state.
3.1.5 Shift register bits
xLogic provides the shift register bits S1 to S8, which are assigned the read-only attribute
in the circuit program. The content of shift register bits can only be modified by means of
the Shift register special function
