10.2.9 Program No. selection input
The general-purpose input port designated as the program selection input with the mode setting
can be used as the program selection 2
0
to 2
2
input. (Refer to section 13.2.5.)
In the external point designation mode (when the expansion input-output unit is not mounted), the
general-purpose input port can be used as point table designation selection 2
0
to 2
3
. (Refer to
the explanation of External point designation mode in section 8.)
(1) For sequential mode

This input allows the program to be jumped to the required tag No. step by a 3-bit input signal
from the external controller (programmable controller, digital switch, etc.). (Tag. No. 1 to 8)

This input is valid only during execution of the PSEL command.

is OFF during PSEL execution.
The step for which tag No. "004" is input will be jumped to.
(2) For palletizing mode

This input is the palletizing program No. selection input.

This input is valid only when the start signal is input.

The input signal and selection program No. are as follow.
1 ... ON 0 ... OFF

(3) For external point designation mode

This input is the point table designation input (when the expansion input/output unit is not
mounted).
The value obtained by subtracting 1 from the designed point table No. is converted to a binary
number, and 1 is set as ON and 0 is set as OFF to this input port.
[Example] For point table No.006:
6 - 1 = 5 (decimal) = 0101 (binary)
