3-2 Input Signal Description
3-2-2 General-purpose input (DI0 to DI15)
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, DI0 to
DI9 can be used to specify the point numbers and DI10 and DI11 to specify the movement speed.
As the table below shows, the point numbers should be input with DI0 to DI9 in binary code, to
specify P0 to P999. The movement speed is specified as 100% when DI10 and DI11 are off. In other
cases, it is set to the speed specified by the parameter. (See "5-2 Parameter Description".)
