(4)
The number of steps required for one instruction differs
depending on the type of instruction. Also, even with the same
instruction, the number of steps occupied varies depending on
whether digit designation is used in the operand, a constant or a
register is used in a double-length operand, etc (1-10 steps/1
instruction).
Also, basically step numbers are not required for vertical connection
lines and horizontal connection lines.
(5)
In a instruction which has multiple inputs, a vertical connection
line cannot be placed immediately before an input. In this case,
insert a dummy contact (such as the NO contact of special relay
S004F which is always ON) immediately before the input.
Example)
The above arrangement is not required for the lowest input of multiple
inputs.
