3-2-2 General-purpose input (DI0 to DI7)
These general-purpose inputs are available to users for handling data input in a program.
These inputs are usually connected to sensors or switches. These inputs can also be directly con-
nected to a PLC output circuit.
As a special function during execution of an ABS-PT or INC-PT point movement command, these
general- purpose inputs can be used to specify the point numbers and movement speed.
The number of general-purpose input (DI) points used to specify the point numbers and speed differs
depending on whether SERVICE mode is enabled or disabled and also on the PRM7 (I/O point
movement command speed parameter) setting.
For example, when PRM7 is 100 in normal mode (SERVICE mode disabled), the point numbers
should be input in binary code with DI0 to DI7 to specify P0 to P255 as shown in the table below.
If PRM7 is 0 in normal mode (SERVICE mode disabled), then point numbers should be input with
DI0 to DI5 in binary code to specify P0 to P63 as shown in the table below. The movement speed is
specified as 100% when both DI6 and DI7 are off. In other cases, it is set to the speed specified by the
parameter. (See "5-2 Parameter Description".) Also see the tables below for more details.

* DI7 functions as the SERVICE mode input when the SERVICE mode function is enabled.
In this case, DI0 to DI6 can be used as the general-purpose inputs.
